/*
|
|
* There are several ways to enumerate physical disks. Unfortunately,
|
|
* none of them are truly complete, so we have to build a union of all of
|
|
* them. Specifically:
|
|
*
|
|
* - IOC2 : This gives us a list of volumes, and by walking the volumes we
|
|
* can enumerate all of the drives attached to volumes including
|
|
* online drives and failed drives.
|
|
* - IOC3 : This gives us a list of all online physical drives including
|
|
* drives that are not part of a volume nor a spare drive. It
|
|
* does not include any failed drives.
|
|
* - IOC5 : This gives us a list of all spare drives including failed
|
|
* spares.
|
|
*
|
|
* The specific edge cases are that 1) a failed volume member can only be
|
|
* found via IOC2, 2) a drive that is neither a volume member nor a spare
|
|
* can only be found via IOC3, and 3) a failed spare can only be found via
|
|
* IOC5.
|
|
*
|
|
* To handle this, walk all of the three lists and use the following
|
|
* routine to add each drive encountered. It quietly succeeds if the
|
|
* drive is already present in the list. It also sorts the list as it
|
|
* inserts new drives.
