Missing size
We are facing a pblm with one D220(HP-UX 11.00) which is having 2 * 2 GB disks.
While comparing the LV sizes and the free size in VGs some space is missing
somewhere.when we do a vgscan it is checking for a disk which is not present.
I took over recently and not sure whether some disk was there or not.Following are the details.
lv1 stand /dev/dsk/c0t8d0 21
lv2 /dev/dsk/c0t8d0 64
lv3 / /dev/dsk/c0t8d0 35
lv4 /tmp /dev/dsk/c0t8d0 16 -- total pe 425
lv6 /opt /dev/dsk/c0t8d0 60
lv7 /usr /dev/dsk/c0t8d0 104
lv8 /var /dev/dsk/c0t8d0 125
lv10 3rdparty /dev/dsk/c0t5d0 50
lv11 mscomc /dev/dsk/c0t5d0 188
lv12 tmp/abcd /dev/dsk/c0t8d0 3 - total pe 246
lv14 tmp/tmpdir /dev/dsk/c0t5d0 5
- Physical volumes ---
PV Name /dev/dsk/c0t5d0
PV Status available
Total PE 508
Free PE 4
PV Name /dev/dsk/c0t8d0
PV Status available
Total PE 507
Free PE 2
#vgscan -a -v
Creating "/etc/lvmtab".
Couldn't stat physical volume "/dev/dsk/c1t2d0":
Invalid argument
/dev/vg00
/dev/dsk/c0t5d0
/dev/dsk/c0t8d0
Scan of Physical Volumes Complete

Re: Missing size
Try this:
# ioscan -fnC disk
This will identify exactly what the system sees in the way of disks.
If your unsure, post the ioscan output.

Re: Missing size
Everything is fine. The reason 'vgscan' complained, is that it tried to do something with your CD ROM drive. The device is
disk 2 8/16/5.2.0 sdisk CLAIMED DEVICE TOSHIBA CD-ROM XM-5401TA
/dev/dsk/c1t2d0 /dev/rdsk/c1t2d0
Don't worry
Cheers
Michael

Re: Missing size
# vgdisplay -v
From what I can see, there is no obvious problem other than the physical extent size of the disks are slightly different.
