.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is designed to provide a way for users to access and control the
|
|
.Fx
|
|
CAM subsystem.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility
|
|
can cause a loss of data and/or system crashes if used improperly.
|
|
Even
|
|
expert users are encouraged to exercise caution when using this command.
|
|
Novice users should stay away from this utility.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility has a number of primary functions, many of which support an optional
|
|
device identifier.
|
|
A device identifier can take one of three forms:
|
|
.Bl -tag -width 14n
|
|
.It deviceUNIT
|
|
Specify a device name and unit number combination, like "da5" or "cd3".
|
|
.It bus:target
|
|
Specify a bus number and target id.
|
|
The bus number can be determined from
|
|
the output of
|
|
.Dq camcontrol devlist .
|
|
The lun defaults to 0.
|
|
.It bus:target:lun
|
|
Specify the bus, target and lun for a device.
|
|
(e.g.\& 1:2:0)
|
|
.El
|
|
.Pp
|
|
The device identifier, if it is specified,
|
|
.Em must
|
|
come immediately after the function name, and before any generic or
|
|
function-specific arguments.
|
|
Note that the
|
|
.Fl n
|
|
and
|
|
.Fl u
|
|
arguments described below will override any device name or unit number
|
|
specified beforehand.
|
|
The
|
|
.Fl n
|
|
and
|
|
.Fl u
|
|
arguments will
|
|
.Em not
|
|
override a specified bus:target or bus:target:lun, however.
|
|
.Pp
|
|
Most of the
|
|
.Nm
|
|
primary functions support these generic arguments:
|
|
.Bl -tag -width 14n
|
|
.It Fl C Ar count
|
|
SCSI command retry count.
|
|
In order for this to work, error recovery
|
|
.Pq Fl E
|
|
must be turned on.
|
|
.It Fl E
|
|
Instruct the kernel to perform generic SCSI error recovery for the given
|
|
command.
|
|
This is needed in order for the retry count
|
|
.Pq Fl C
|
|
to be honored.
|
|
Other than retrying commands, the generic error recovery in
|
|
the code will generally attempt to spin up drives that are not spinning.
|
|
It may take some other actions, depending upon the sense code returned from
|
|
the command.
|
|
.It Fl n Ar dev_name
|
|
Specify the device type to operate on, e.g.\& "da", "cd".
|
|
.It Fl t Ar timeout
|
|
SCSI command timeout in seconds.
|
|
This overrides the default timeout for
|
|
any given command.
|
|
.It Fl u Ar unit_number
|
|
Specify the device unit number, e.g.\& "1", "5".
|
|
.It Fl v
|
|
Be verbose, print out sense information for failed SCSI commands.
|
|
.El
|
|
.Pp
|
|
Primary command functions:
|
|
.Bl -tag -width periphlist
|
|
.It Ic devlist
|
|
List all physical devices (logical units) attached to the CAM subsystem.
|
|
This also includes a list of peripheral drivers attached to each device.
|
|
With the
|
|
.Fl v
|
|
argument, SCSI bus number, adapter name and unit numbers are printed as
|
|
well.
|
|
On the other hand, with the
|
|
.Fl b
|
|
argument, only the bus adapter, and unit information will be printed, and
|
|
device information will be omitted.
|
|
.It Ic periphlist
|
|
List all peripheral drivers attached to a given physical device (logical
|
|
unit).
|
|
.It Ic tur
|
|
Send the SCSI test unit ready (0x00) command to the given device.
|
|
The
|
|
.Nm
|
|
utility will report whether the device is ready or not.
|
|
.It Ic inquiry
|
|
Send a SCSI inquiry command (0x12) to a device.
|
|
By default,
|
|
.Nm
|
|
will print out the standard inquiry data, device serial number, and
|
|
transfer rate information.
|
|
The user can specify that only certain types of
|
|
inquiry data be printed:
|
|
.Bl -tag -width 4n
|
|
.It Fl D
|
|
Get the standard inquiry data.
|
|
.It Fl S
|
|
Print out the serial number.
|
|
If this flag is the only one specified,
|
|
.Nm
|
|
will not print out "Serial Number" before the value returned by the drive.
|
|
This is to aid in script writing.
|
|
.It Fl R
|
|
Print out transfer rate information.
|
|
.El
|
|
.It Ic identify
|
|
Send a ATA identify command (0xec) to a device.
|
|
.It Ic reportluns
|
|
Send the SCSI REPORT LUNS (0xA0) command to the given device.
|
|
By default,
|
|
.Nm
|
|
will print out the list of logical units (LUNs) supported by the target device.
|
|
There are a couple of options to modify the output:
|
|
.Bl -tag -width 14n
|
|
.It Fl c
|
|
Just print out a count of LUNs, not the actual LUN numbers.
|
|
.It Fl l
|
|
Just print out the LUNs, and do not print out the count.
|
|
.It Fl r Ar reporttype
|
|
Specify the type of report to request from the target:
|
|
.Bl -tag -width 012345678
|
|
.It default
|
|
Return the default report.
|
|
This is the
|
|
.Nm
|
|
default.
|
|
Most targets will support this report if they support the REPORT LUNS
|
|
command.
|
|
.It wellknown
|
|
Return only well known LUNs.
|
|
.It all
|
|
Return all available LUNs.
|
|
.El
|
|
.El
|
|
.Pp
|
|
.Nm
|
|
will try to print out LUN numbers in a reasonable format.
|
|
It can understand the peripheral, flat, LUN and extended LUN formats.
|
|
.It Ic readcap
|
|
Send the SCSI READ CAPACITY command to the given device and display
|
|
the results.
|
|
If the device is larger than 2TB, the SCSI READ CAPACITY (16) service
|
|
action will be sent to obtain the full size of the device.
|
|
By default,
|
|
.Nm
|
|
will print out the last logical block of the device, and the blocksize of
|
|
the device in bytes.
|
|
To modify the output format, use the following options:
|
|
.Bl -tag -width 5n
|
|
.It Fl b
|
|
Just print out the blocksize, not the last block or device size.
|
|
This cannot be used with
|
|
.Fl N
|
|
or
|
|
.Fl s .
|
|
.It Fl h
|
|
Print out the device size in human readable (base 2, 1K == 1024) format.
|
|
This implies
|
|
.Fl N
|
|
and cannot be used with
|
|
.Fl q
|
|
or
|
|
.Fl b .
|
|
.It Fl H
|
|
Print out the device size in human readable (base 10, 1K == 1000) format.
|
|
.It Fl N
|
|
Print out the number of blocks in the device instead of the last logical
|
|
block.
|
|
.It Fl q
|
|
Quiet, print out the numbers only (separated by a comma if
|
|
.Fl b
|
|
or
|
|
.Fl s
|
|
are not specified).
|
|
.It Fl s
|
|
Print out the last logical block or the size of the device only, and omit
|
|
the blocksize.
|
|
.El
|
|
.It Ic start
|
|
Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
|
|
start bit set.
|
|
.It Ic stop
|
|
Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
|
|
start bit cleared.
|
|
.It Ic load
|
|
Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
|
|
start bit set and the load/eject bit set.
|
|
.It Ic eject
|
|
Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
|
|
start bit cleared and the load/eject bit set.
|
|
.It Ic rescan
|
|
Tell the kernel to scan all busses in the system (with the
|
|
.Ar all
|
|
argument), the given bus (XPT_SCAN_BUS), or bus:target:lun
|
|
(XPT_SCAN_LUN) for new devices or devices that have gone away.
|
|
The user
|
|
may specify a scan of all busses, a single bus, or a lun.
|
|
Scanning all luns
|
|
on a target is not supported.
|
|
.It Ic reset
|
|
Tell the kernel to reset all busses in the system (with the
|
|
.Ar all
|
|
argument) or the given bus (XPT_RESET_BUS) by issuing a SCSI bus
|
|
reset for that bus, or to reset the given bus:target:lun
|
|
(XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after
|
|
connecting to that device.
|
|
Note that this can have a destructive impact
|
|
on the system.
|
|
.It Ic defects
|
|
Send the SCSI READ DEFECT DATA (10) command (0x37) to the given device, and
|
|
print out any combination of: the total number of defects, the primary
|
|
defect list (PLIST), and the grown defect list (GLIST).
|
|
.Bl -tag -width 11n
|
|
.It Fl f Ar format
|
|
The three format options are:
|
|
.Em block ,
|
|
to print out the list as logical blocks,
|
|
.Em bfi ,
|
|
to print out the list in bytes from index format, and
|
|
.Em phys ,
|
|
to print out the list in physical sector format.
|
|
The format argument is
|
|
required.
|
|
Most drives support the physical sector format.
|
|
Some drives
|
|
support the logical block format.
|
|
Many drives, if they do not support the
|
|
requested format, return the data in an alternate format, along with sense
|
|
information indicating that the requested data format is not supported.
|
|
The
|
|
.Nm
|
|
utility
|
|
attempts to detect this, and print out whatever format the drive returns.
|
|
If the drive uses a non-standard sense code to report that it does not
|
|
support the requested format,
|
|
.Nm
|
|
will probably see the error as a failure to complete the request.
|
|
.It Fl G
|
|
Print out the grown defect list.
|
|
This is a list of bad blocks that have
|
|
been remapped since the disk left the factory.
|
|
.It Fl P
|
|
Print out the primary defect list.
|
|
.El
|
|
.Pp
|
|
If neither
|
|
.Fl P
|
|
nor
|
|
.Fl G
|
|
is specified,
|
|
.Nm
|
|
will print out the number of defects given in the READ DEFECT DATA header
|
|
returned from the drive.
|
|
Some drives will report 0 defects if neither the primary or grown defect
|
|
lists are requested.
|
|
.It Ic modepage
|
|
Allows the user to display and optionally edit a SCSI mode page.
|
|
The mode
|
|
page formats are located in
|
|
.Pa /usr/share/misc/scsi_modes .
|
|
This can be overridden by specifying a different file in the
|
|
.Ev SCSI_MODES
|
|
environment variable.
|
|
The
|
|
.Ic modepage
|
|
command takes several arguments:

|
.Nm
|
|
uses to display mode page values.
|
|
The editor will be invoked if
|
|
.Nm
|
|
detects that standard input is terminal.
|
|
.It Fl l
|
|
Lists all available mode pages.
|
|
.It Fl m Ar mode_page
|

.El
|
|
.It Ic cmd
|
|
Allows the user to send an arbitrary ATA or SCSI CDB to any device.
|
|
The
|
|
.Ic cmd
|
|
function requires the
|
|
.Fl c
|
|
argument to specify SCSI CDB or the
|
|
.Fl a
|
|
argument to specify ATA Command Block registers values.
|
|
Other arguments are optional, depending on
|
|
the command type.
|
|
The command and data specification syntax is documented
|
|
in
|
|
.Xr cam_cdbparse 3 .
|
|
NOTE: If the CDB specified causes data to be transferred to or from the
|
|
SCSI device in question, you MUST specify either
|
|
.Fl i
|
|
or
|
|
.Fl o .
|
|
.Bl -tag -width 17n
|
|
.It Fl a Ar cmd Op args
|

features, lba_low, lba_mid, lba_high, device, lba_low_exp, lba_mid_exp.
|
|
lba_high_exp, features_exp, sector_count, sector_count_exp).
|
|
.It Fl c Ar cmd Op args
|
|
This specifies the SCSI CDB.
|
|
SCSI CDBs may be 6, 10, 12 or 16 bytes.
|
|
.It Fl d
|
|
Specifies DMA protocol to be used for ATA command.
|
|
.It Fl f
|
|
Specifies FPDMA (NCQ) protocol to be used for ATA command.
|
|
.It Fl i Ar len Ar fmt
|
|
This specifies the amount of data to read, and how it should be displayed.
|
|
If the format is
|
|
.Sq - ,
|
|
.Ar len
|
|
bytes of data will be read from the device and written to standard output.
|
|
.It Fl o Ar len Ar fmt Op args
|
|
This specifies the amount of data to be written to a device, and the data
|
|
that is to be written.
|
|
If the format is
|
|
.Sq - ,
|
|
.Ar len
|
|
bytes of data will be read from standard input and written to the device.
|
|
.It Fl r Ar fmt
|
|
This specifies that 11 result ATA Command Block registers should be displayed
|
|
(status, error, lba_low, lba_mid, lba_high, device, lba_low_exp, lba_mid_exp,
|
|
lba_high_exp, sector_count, sector_count_exp), and how.
|
|
If the format is
|
|
.Sq - ,
|
|
11 result registers will be written to standard output in hex.
|
|
.El
|
|
.It Ic smpcmd
|
|
Allows the user to send an arbitrary Serial
|
|
Management Protocol (SMP) command to a device.
|
|
The
|
|
.Ic smpcmd
|
|
function requires the
|
|
.Fl r
|
|
argument to specify the SMP request to be sent, and the
|
|
.Fl R
|
|
argument to specify the format of the SMP response.
|
|
The syntax for the SMP request and response arguments is documented in
|
|
.Xr cam_cdbparse 3 .
|
|
.Pp
|
|
Note that SAS adapters that support SMP passthrough (at least the currently
|
|
known adapters) do not accept CRC bytes from the user in the request and do
|
|
not pass CRC bytes back to the user in the response.
|
|
Therefore users should not include the CRC bytes in the length of the
|
|
request and not expect CRC bytes to be returned in the response.
|
|
.Bl -tag -width 17n
|
|
.It Fl r Ar len Ar fmt Op args
|
|
This specifies the size of the SMP request, without the CRC bytes, and the
|
|
SMP request format.
|
|
If the format is
|
|
.Sq - ,
|
|
.Ar len
|
|
bytes of data will be read from standard input and written as the SMP
|
|
request.
|
|
.It Fl R Ar len Ar fmt Op args
|
|
This specifies the size of the buffer allocated for the SMP response, and
|
|
the SMP response format.
|
|
If the format is
|
|
.Sq - ,
|
|
.Ar len
|
|
bytes of data will be allocated for the response and the response will be
|
|
written to standard output.
|
|
.El
|
|
.It Ic smprg
|
|
Allows the user to send the Serial Management Protocol (SMP) Report General
|
|
command to a device.
|
|
.Nm
|
|
will display the data returned by the Report General command.
|
|
If the SMP target supports the long response format, the additional data
|
|
will be requested and displayed automatically.
|
|
.Bl -tag -width 8n
|
|
.It Fl l
|
|
Request the long response format only.
|
|
Not all SMP targets support the long response format.
|
|
This option causes
|
|
.Nm
|
|
to skip sending the initial report general request without the long bit set
|
|
and only issue a report general request with the long bit set.
|
|
.El
|
|
.It Ic smppc
|
|
Allows the user to issue the Serial Management Protocol (SMP) PHY Control
|
|
command to a device.
|
|
This function should be used with some caution, as it can render devices
|
|
inaccessible, and could potentially cause data corruption as well.
|
|
The
|
|
.Fl p
|
|
argument is required to specify the PHY to operate on.
|
|
.Bl -tag -width 17n
|
|
.It Fl p Ar phy
|
|
Specify the PHY to operate on.
|
|
This argument is required.
|
|
.It Fl l
|
|
Request the long request/response format.
|
|
Not all SMP targets support the long response format.
|
|
For the PHY Control command, this currently only affects whether the
|
|
request length is set to a value other than 0.
|
|
.It Fl o Ar operation
|
|
Specify a PHY control operation.
|
|
Only one
|
|
.Fl o
|
|
operation may be specified.
|
|
The operation may be specified numerically (in decimal, hexadecimal, or octal)
|
|
or one of the following operation names may be specified:
|
|
.Bl -tag -width 16n
|
|
.It nop
|
|
No operation.
|
|
It is not necessary to specify this argument.
|
|
.It linkreset
|
|
Send the LINK RESET command to the phy.
|
|
.It hardreset
|
|
Send the HARD RESET command to the phy.
|
|
.It disable
|
|
Send the DISABLE command to the phy.
|
|
Note that the LINK RESET or HARD RESET commands should re-enable the phy.
|
|
.It clearerrlog
|
|
Send the CLEAR ERROR LOG command.
|
|
This clears the error log counters for the specified phy.
|
|
.It clearaffiliation
|
|
Send the CLEAR AFFILIATION command.
|
|
This clears the affiliation from the STP initiator port with the same SAS
|
|
address as the SMP initiator that requests the clear operation.
|
|
.It sataportsel
|
|
Send the TRANSMIT SATA PORT SELECTION SIGNAL command to the phy.
|
|
This will cause a SATA port selector to use the given phy as its active phy
|
|
and make the other phy inactive.
|
|
.It clearitnl
|
|
Send the CLEAR STP I_T NEXUS LOSS command to the PHY.
|
|
.It setdevname
|
|
Send the SET ATTACHED DEVICE NAME command to the PHY.
|
|
This requires the
|
|
.Fl d
|
|
argument to specify the device name.
|
|
.El
|
|
.It Fl d Ar name
|
|
Specify the attached device name.
|
|
This option is needed with the
|
|
.Fl o Ar setdevname
|
|
phy operation.
|
|
The name is a 64-bit number, and can be specified in decimal, hexadecimal
|
|
or octal format.
|
|
.It Fl m Ar rate
|
|
Set the minimum physical link rate for the phy.
|
|
This is a numeric argument.

Turn on the long response format for the underlying SMP commands used for
|
|
this command.
|
|
.El
|
|
.It Ic debug
|
|
Turn on CAM debugging printfs in the kernel.
|
|
This requires options CAMDEBUG
|
|
in your kernel config file.
|
|
WARNING: enabling debugging printfs currently
|
|
causes an EXTREME number of kernel printfs.
|
|
You may have difficulty
|
|
turning off the debugging printfs once they start, since the kernel will be
|
|
busy printing messages and unable to service other requests quickly.
|
|
The
|
|
.Ic debug
|
|
function takes a number of arguments:
|
|
.Bl -tag -width 18n
|
|
.It Fl I
|
|
Enable CAM_DEBUG_INFO printfs.
|
|
.It Fl P
|

|
Enable CAM_DEBUG_SUBTRACE printfs.
|
|
.It Fl X
|
|
Enable CAM_DEBUG_XPT printfs.
|
|
.It Fl c
|
|
Enable CAM_DEBUG_CDB printfs.
|
|
This will cause the kernel to print out the
|
|
SCSI CDBs sent to the specified device(s).
|
|
.It Fl p
|
|
Enable CAM_DEBUG_PROBE printfs.
|
|
.It all
|
|
Enable debugging for all devices.
|
|
.It off
|
|
Turn off debugging for all devices
|
|
.It bus Ns Op :target Ns Op :lun
|
|
Turn on debugging for the given bus, target or lun.
|
|
If the lun or target
|
|
and lun are not specified, they are wildcarded.
|
|
(i.e., just specifying a
|
|
bus turns on debugging printfs for all devices on that bus.)
|
|
.El
|
|
.It Ic tags
|
|
Show or set the number of "tagged openings" or simultaneous transactions
|
|
we attempt to queue to a particular device.
|
|
By default, the
|
|
.Ic tags
|
|
command, with no command-specific arguments (i.e., only generic arguments)
|
|
prints out the "soft" maximum number of transactions that can be queued to
|
|
the device in question.
|
|
For more detailed information, use the
|
|
.Fl v
|
|
argument described below.
|
|
.Bl -tag -width 7n
|
|
.It Fl N Ar tags
|
|
Set the number of tags for the given device.
|
|
This must be between the
|
|
minimum and maximum number set in the kernel quirk table.
|
|
The default for
|
|
most devices that support tagged queueing is a minimum of 2 and a maximum
|
|
of 255.
|
|
The minimum and maximum values for a given device may be
|
|
determined by using the
|
|
.Fl v
|
|
switch.
|
|
The meaning of the
|
|
.Fl v
|
|
switch for this
|
|
.Nm
|
|
subcommand is described below.
|
|
.It Fl q
|
|
Be quiet, and do not report the number of tags.
|
|
This is generally used when
|
|
setting the number of tags.
|
|
.It Fl v
|
|
The verbose flag has special functionality for the
|
|
.Em tags
|
|
argument.
|
|
It causes
|
|
.Nm
|
|
to print out the tagged queueing related fields of the XPT_GDEV_TYPE CCB:
|
|
.Bl -tag -width 13n
|
|
.It dev_openings
|
|
This is the amount of capacity for transactions queued to a given device.
|
|
.It dev_active
|
|
This is the number of transactions currently queued to a device.
|
|
.It devq_openings
|
|
This is the kernel queue space for transactions.
|
|
This count usually mirrors
|
|
dev_openings except during error recovery operations when
|
|
the device queue is frozen (device is not allowed to receive
|
|
commands), the number of dev_openings is reduced, or transaction
|
|
replay is occurring.
|
|
.It devq_queued
|
|
This is the number of transactions waiting in the kernel queue for capacity
|
|
on the device.
|
|
This number is usually zero unless error recovery is in
|
|
progress.
|
|
.It held
|
|
The held count is the number of CCBs held by peripheral drivers that have
|
|
either just been completed or are about to be released to the transport
|
|
layer for service by a device.
|
|
Held CCBs reserve capacity on a given
|
|
device.
|
|
.It mintags
|
|
This is the current "hard" minimum number of transactions that can be
|
|
queued to a device at once.
|
|
The
|
|
.Ar dev_openings
|
|
value above cannot go below this number.
|
|
The default value for
|
|
.Ar mintags
|
|
is 2, although it may be set higher or lower for various devices.
|
|
.It maxtags
|
|
This is the "hard" maximum number of transactions that can be queued to a
|
|
device at one time.
|
|
The
|
|
.Ar dev_openings
|
|
value cannot go above this number.
|
|
The default value for
|
|
.Ar maxtags
|
|
is 255, although it may be set higher or lower for various devices.
|
|
.El
|
|
.El
|
|
.It Ic negotiate
|
|
Show or negotiate various communication parameters.
|
|
Some controllers may
|
|
not support setting or changing some of these values.
|
|
For instance, the
|
|
Adaptec 174x controllers do not support changing a device's sync rate or
|
|
offset.
|
|
The
|
|
.Nm
|
|
utility
|
|
will not attempt to set the parameter if the controller indicates that it
|
|
does not support setting the parameter.
|
|
To find out what the controller
|
|
supports, use the
|
|
.Fl v
|
|
flag.
|
|
The meaning of the
|
|
.Fl v
|
|
flag for the
|
|
.Ic negotiate
|
|
command is described below.
|
|
Also, some controller drivers do not support
|
|
setting negotiation parameters, even if the underlying controller supports
|
|
negotiation changes.
|
|
Some controllers, such as the Advansys wide
|
|
controllers, support enabling and disabling synchronous negotiation for
|
|
a device, but do not support setting the synchronous negotiation rate.
|
|
.Bl -tag -width 17n
|
|
.It Fl a
|
|
Attempt to make the negotiation settings take effect immediately by sending
|
|
a Test Unit Ready command to the device.
|
|
.It Fl c
|
|
Show or set current negotiation settings.
|
|
This is the default.
|
|
.It Fl D Ar enable|disable
|
|
Enable or disable disconnection.
|
|
.It Fl M Ar mode
|
|
Set ATA mode.
|
|
.It Fl O Ar offset
|
|
Set the command delay offset.
|
|
.It Fl q
|
|
Be quiet, do not print anything.
|
|
This is generally useful when you want to
|
|
set a parameter, but do not want any status information.
|
|
.It Fl R Ar syncrate
|
|
Change the synchronization rate for a device.
|
|
The sync rate is a floating
|
|
point value specified in MHz.
|
|
So, for instance,
|
|
.Sq 20.000
|
|
is a legal value, as is
|
|
.Sq 20 .
|
|
.It Fl T Ar enable|disable
|
|
Enable or disable tagged queueing for a device.
|
|
.It Fl U
|
|
Show or set user negotiation settings.
|
|
The default is to show or set
|
|
current negotiation settings.
|
|
.It Fl v
|
|
The verbose switch has special meaning for the
|
|
.Ic negotiate
|
|
subcommand.
|
|
It causes
|
|
.Nm
|
|
to print out the contents of a Path Inquiry (XPT_PATH_INQ) CCB sent to the
|
|
controller driver.
|
|
.It Fl W Ar bus_width
|
|
Specify the bus width to negotiate with a device.
|
|
The bus width is
|
|
specified in bits.
|
|
The only useful values to specify are 8, 16, and 32
|
|
bits.
|
|
The controller must support the bus width in question in order for
|
|
the setting to take effect.
|
|
.El
|
|
.Pp
|
|
In general, sync rate and offset settings will not take effect for a
|
|
device until a command has been sent to the device.
|
|
The
|
|
.Fl a
|
|
switch above will automatically send a Test Unit Ready to the device so
|
|
negotiation parameters will take effect.
|
|
.It Ic format
|
|
Issue the
|
|
.Tn SCSI
|
|
FORMAT UNIT command to the named device.
|
|
.Pp
|
|
.Em WARNING! WARNING! WARNING!
|
|
.Pp
|
|
Low level formatting a disk will destroy ALL data on the disk.
|
|
Use
|
|
extreme caution when issuing this command.
|
|
Many users low-level format
|
|
disks that do not really need to be low-level formatted.
|
|
There are
|
|
relatively few scenarios that call for low-level formatting a disk.
|
|
One reason for
|
|
low-level formatting a disk is to initialize the disk after changing
|
|
its physical sector size.
|
|
Another reason for low-level formatting a disk
|
|
is to revive the disk if you are getting "medium format corrupted" errors
|
|
from the disk in response to read and write requests.
|
|
.Pp
|
|
Some disks take longer than others to format.
|
|
Users should specify a
|
|
timeout long enough to allow the format to complete.
|
|
The default format
|
|
timeout is 3 hours, which should be long enough for most disks.
|
|
Some hard
|
|
disks will complete a format operation in a very short period of time
|
|
(on the order of 5 minutes or less).
|
|
This is often because the drive
|
|
does not really support the FORMAT UNIT command -- it just accepts the
|
|
command, waits a few minutes and then returns it.
|
|
.Pp
|
|
The
|
|
.Sq format
|
|
subcommand takes several arguments that modify its default behavior.
|
|
The
|
|
.Fl q
|
|
and
|
|
.Fl y
|
|
arguments can be useful for scripts.
|
|
.Bl -tag -width 6n
|
|
.It Fl q
|
|
Be quiet, do not print any status messages.
|
|
This option will not disable
|
|
the questions, however.
|
|
To disable questions, use the
|
|
.Fl y
|
|
argument, below.
|
|
.It Fl r
|
|
Run in
|
|
.Dq report only
|
|
mode.
|
|
This will report status on a format that is already running on the drive.
|
|
.It Fl w
|
|
Issue a non-immediate format command.
|
|
By default,
|
|
.Nm
|
|
issues the FORMAT UNIT command with the immediate bit set.
|
|
This tells the
|
|
device to immediately return the format command, before the format has
|
|
actually completed.
|
|
Then,
|
|
.Nm
|
|
gathers
|
|
.Tn SCSI
|
|
sense information from the device every second to determine how far along
|
|
in the format process it is.
|
|
If the
|
|
.Fl w
|
|
argument is specified,
|
|
.Nm
|
|
will issue a non-immediate format command, and will be unable to print any
|
|
information to let the user know what percentage of the disk has been
|
|
formatted.
|
|
.It Fl y
|
|
Do not ask any questions.

.It Fl w
|
|
Issue a non-immediate sanitize command.
|
|
By default,
|
|
.Nm
|
|
issues the SANITIZE command with the immediate bit set.
|
|
This tells the

.Sh BUGS
|
|
The code that parses the generic command line arguments does not know that
|
|
some of the subcommands take multiple arguments.
|
|
So if, for instance, you
|
|
tried something like this:
|
|
.Bd -literal -offset indent
|
|
camcontrol cmd -n da -u 1 -c "00 00 00 00 00 v" 0x00 -v
|
|
.Ed
|
|
.Pp
|
|
The sense information from the test unit ready command would not get
|
|
printed out, since the first
|
|
.Xr getopt 3
|
|
call in
|
|
.Nm
|
|
bails out when it sees the second argument to
|
|
.Fl c
|
|
(0x00),
|
|
above.
|
|
Fixing this behavior would take some gross code, or changes to the
|
|
.Xr getopt 3
|
|
interface.
|
|
The best way to circumvent this problem is to always make sure
|
|
to specify generic
|
|
.Nm
|
|
arguments before any command-specific arguments.
|
