ia64dsk: The disk for dev_t d00009b appears to have grown since the partition table was written.

We are seeing a message about a disk to have grown since the partition table was written.

We had a storage migration using an HP MPX200 router

09b appears to have grown since the partition table was written.
ia64dsk: The disk for dev_t d00009b appears to have grown since the partition table was written.

To identify the disk, check /dev

root@hp-ux:~ # ls -ltraR /dev | grep 009b
crw-r—– 1 bin sys 13 0x00009b Feb 12 14:29 disk30
brw-r—– 1 bin sys 1 0x00009b Feb 12 14:29 disk30

According to idisk, we need to use -G option but it is not documented on the manual page

root@hp-ux:~ # idisk -p /dev/rdisk/disk30
idisk version: 1.44

NOTE: This disk appears to have grown since the partition
table was written. Use idisk with the -G option to
extend the usable space to fill the disk.

There should be a difference in cylinders and blocks between the two disks that is causing this message
