Missing size

STANLY_1 — Wed, 29 Jan 2003 05:39:47 GMT

Hai all

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

it could be that there was a volume attached that is not currently.

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.

Hi,

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

If your still worried about the size difference of the volume groups, post the output of this:

# vgdisplay -v

From what I can see, there is no obvious problem other than the physical extent size of the disks are slightly different.
