Re: vgcfgrestore - unable to restore config bec. of PV size???
But when this new disk was plugged into the system, we still see that it is less than the disk sizes of the other disks currently installed. Here's a diskinfo o/p for your reference (c6t0d0 is the replaced disk)
SCSI describe of /dev/rdsk/c6t0d0:
vendor: SEAGATE
product id: ST336753LC
type: direct access
size: 35566479 Kbytes
bytes per sector: 512
---------------------------------------------
SCSI describe of /dev/rdsk/c4t8d0:
vendor: HP 36.4G
product id: ST336753LC
type: direct access
size: 35566480 Kbytes
bytes per sector: 512

It is odd that c6t0d0 is seagate and c4t8d0 is hp. I admit to have never seen this.
I'd check my firmware on everything including the PDC. I'm thinking the new disk is the latest and greatest and you're old somewhere in the GSP, PDC, ...

Even though the mfr is Seagate with the exact same Seagate product number, the vendor ID is the giveaway that it is not the same disk. There are a large number of reasons for the variations, none of which make it easy for sysadmins. You can always replace the disk with a bigger one but the reverse won't work.
So diskinfo is your friend -- hopefully you have this info before you have to replace the disk. Always replace with the same vendor ID and product ID. Sometimes, this information is printed on the drive...sometimes not.

SolutionI have one question for you, here the problem is becuase this guy is using vgcfgrestore and disks are in PVG.
size if disk is just 1KB less....
so what would happen if he removes disks from PVG temporary.....add it with normal LVM command..........put back in PVG and sync it.
It should work right ??
Lemme know if my understanding is correct.

remove the disk entry from PVG from /etc/lvmpvg add disk as explained by Bill and then put the entry back in PVG file.
