/dev/vg02/group was not matched with any Physical Volumes

[Juquin_3]

Hi everybody ,

I can't see all the data disks (a Nike technology discs with LUN) on my server ,
I try to make vgchange -a y /dev/vg02 =>does not exist in the /etc/lvmtab !!

I try to make vgextend /dev/vg02 /dev/dsk/c0t0d0 => /dev/vg02 does not exist in teh /etc/lvmtab

I try to move /etc/lvmtab into /etc/lvmtab/old and tape #vgscan -av =>the volume group /dev/vg02/group was not matched with any physical volumes

I reboot my server , I tape #search =>the system does recognize data discs !!

Does someone have a solution ?

Thanks a lot

Are you sure that the disks are assigned to you server in the storage device?

What do you see in "ioscan -ifnCdisk" ?

Check if all disks in ioscan output match some vg. I think that disks that hold the vg02 are no longer exist in the system and you have only /dev/vg02/ directory with files that does not match the hardware.

Steps:
ioscan -fnCdisk
pvdisplay -v /dev/dsk/cXtXdX

ioscan -fnC disk =>nothing is display !!

pvdisplay -v /dev/dsk/c0t0d0 =>Cannot display physical volume

I can't all the disks !!

If i break to boot and tape >search => i see only disks system (VG00) not the data !!

I'd check all the cables are attached to the storage.

[John McWilliams_1]

Are the disks on local storage on on a SAN ?
CHeck the cables but also check the power to the disk cabinet. Do you have green lights on the front of the disks.
If on a SAN also check that the zoning is correct on the fibre switch, and that the disks are set up on the san to enable the server to see them.

After verifying the cables/fibres are correct, then ensure the required driver(s) are installed... for LVM command to work.. u have to be able to see it with ioscan.
