Is the disk already replaced?

Basic steps are

- pvchange -a n ...

- swap disk

- ioscan

- vgcfgrestore ...

- vgchange ...

- lvlnboot -R

Hello Torsten,

Thank you for your reply. This system does not have LVM online replacement (OLR) functionality available so in this case i can not use this option. Is there any other idea for this ?

If the disk is NO_HW in ioscan, just skip the lvchange step and pull the disk.

Ioscan shows it as claimed:

ioscan -fnC disk
Class I H/W Path Driver S/W State H/W Type Description
===========================================================================
disk 0 1/0/0/3/0.6.0 sdisk CLAIMED DEVICE HP 36.4GST336753LC
/dev/dsk/c0t6d0 /dev/rdsk/c0t6d0

Try

vgchange -a y vg00

and check again with vgdisplay.

OR

with you want to replace the disk, replace it now, since it is UNAVAILABLE in vgdisplay

Hello

vgchange -a y fails –a option is not recognized, as the LVM OLR feature is not installed.

if i remove the disk , may it couse the panic on the system ? since it shows as claimed on ioscan
