Hi gurus,
I was happily scripting a couple of weeks ago and came across something
that produced a message similar to this (off the top of my head)
Warning: The label contents does not match the geometry reported by the
physical device.
Now I can not remember the command I ran, but I want to use it in another
script. I was busy writing a script to report on raw disk sizes as seen by
Solaris (not Veritas), and I was playing with commands like
format, prtvtoc, fmthard
I've been searching the web and sunsolve, but I can't find out what it is I
did. Makes me want to "script" to record everything I do... !
The situation I have is that sometimes when the storage administrators
allocate a whole bunch of LUNs I do not check each individually, and
sometimes I don't realise I am not seeing the full LUN (eg if the first
sector of an expanded LUN was previously the first sector of a smaller
LUN). I am trying to write a script which will tell me where I may be
using LUNs without getting access to the whole full size of the LUN.
moreover, I have tried to write something to compare the output of fdisk -g
with that of fdisk -G, but I always get the following message:
# fdisk -g /dev/rdsk/c3t11d4s2
* Label geometry for device /dev/rdsk/c3t11d4s2
* PCYL NCYL ACYL BCYL NHEAD NSECT SECSIZ
39516 39516 2 0 15 96 512
# fdisk -G /dev/rdsk/c3t11d4s2
/dev/rdsk/c3t11d4s2: Cannot get physical disk geometry.
devinfo appears totally useless, and on Solaris 2.6 I get for -g and -G
both:
Disk does not support fixed disk partition table
Any ideas/suggestions ?
Thanx,
_Johan
