Hi Amar ,

Use this command to check the disks , which are part and not part of vg , i,e which disks are exisitng in the system,

# ioscan -fnC disk

[ You can see all the disk internal as well as external ]

# diskinfo -v /dev/dsk/cxtydz
( It will show the details of that disk)

Hope this will help you,

Cheers,
Raj.

ioscan -funCdisk

[Rick Garland · Accepted solution]

ioscan -fnCdisk


This will list the disks the system sees. Should be CLAIMED.

Careful, this does not account for MC ServiceGuard.

[Raj D.]

As Rick said , the status should be CLAIMED. For all operational disk it has to be CLAIMED.
If the status is NO_HW , that means the disk is not present or not recognized by the system in the systm.

Cheers,

Hi

execute strings /etc/lvmtab
From there u can get information about all the disks incurrently imported VG. If u hae exported any vg, /etc/lvmtab will also be missing these disks.

execute ioscan -fnC disk..This will show u all the disks that are accessible to the server.

Regards
CS

Hello Amar,

As the others have stated ioscan -fnC disk will display all of the disks

This includes all of the alternate paths, if you are using dual paths to the disks

One way to determine which disks are PV links is to do vgdisplay -v /dev/vg04

The disk portion of the ouptput will tell you if a disk has an alternate path.
