check unused disk

[Fauziah Mahdan]

Hi all, I have 2 disk for my hpux 11.23
How do I know which disk has been used and which disk is still free.
From ioscan -fnC disk
1) dvdrom
2) disk1 /dev/dsk/c0t0d0 /dev/rdsk/c0t0d0 73G
3) disk2 /dev/dsk/c2t0d0 /dev/rdsk/c2todo 73G

From command strings /etc/lvmtab
/dev/vg00
/dev/dsk/c2t1d0s2

Pls help
Fauziah

Yes by looking at the lvmtab file you should see this..It looks like in your case you are not using LVM but anyway disk connected to conroller 2 is already used which is /dev/dsk/c2t0d0
The free disk is /dev/dsk/c0t0d0

Hi Fauziah,

It's kind a odd seeing data you give..
The disk on lvmtab does not exist on you ioscan?? Or do you put wrong info?

regards,
Sandy

Hi,

your ioscan information may be wrong. As per your lvmtab information the disk which is connected to the second controller /dev/dsk/c2t1d0 is used and /dev/dsk/c0t0d0 is free

From your ioscan and lvmtab: /dev/dsk/c2t0d0 is not used. You can double check it with SAM. In SAM /dev/dsk/c2t0d0 should be marked as unused.
