/*
|
|
* Solaris is somewhat picky about how many heads and sectors per track you
|
|
* have defined in mode pages 3 and 4. These values seem to cause Solaris
|
|
* to get the capacity more or less right when you run the format tool.
|
|
* They still have problems when dealing with devices larger than 1TB,
|
|
* but there isn't anything we can do about that.
|
|
*
|
|
* For smaller LUN sizes, this ends up causing the number of cylinders to
|
|
* work out to 0. Solaris actually recognizes that and comes up with its
|
|
* own bogus geometry to fit the actual capacity of the drive. They really
|
|
* should just give up on geometry and stick to the read capacity
|
|
* information alone for modern disk drives.
|
|
*
|
|
* One thing worth mentioning about Solaris' mkfs command is that it
|
|
* doesn't like sectors per track values larger than 256. 512 seems to
|
|
* work okay for format, but causes problems when you try to make a
|
|
* filesystem.
|
|
*
|
|
* Another caveat about these values: the product of these two values
|
|
* really should be a power of 2. This is because of the simplistic
|
|
* shift-based calculation that we have to use on the i386 platform to
|
|
* calculate the number of cylinders here. (If you use a divide, you end
|
|
* up calling __udivdi3(), which is a hardware FP call on the PC. On the
|
|
* XScale, it is done in software, so you can do that from inside the
|
|
* kernel.)
|
|
*
|
|
* So for the current values (256 S/T, 128 H), we get 32768, which works
|
|
* very nicely for calculating cylinders.
|
|
*
|
|
* If you want to change these values so that their product is no longer a
|
|
* power of 2, re-visit the calculation in ctl_init_page_index(). You may
|
|
* need to make it a bit more complicated to get the number of cylinders
|
|
* right.
