Move the alter disk from one system to another.

In AIX® 5.3, the alt_disk_install command is replaced by the alt_disk_copy, alt_disk_mksysb, and alt_rootvg_op commands.

Move the alter disk from one system to another.
- alt_rootvg_op command to copy rootvg.
- diag ; task selection ; Hot Plug Task ; PCI ; Remove
- Move the disk to New system.
- Boot from SMS menu.

# alt_disk_copy -BOd hdiskx

The -B option tells alt_disk_copy not to change the bootlist to this new copy of rootvg, the -O option will remove devices from your customized ODM database.

##################

From the alt_disk_copy man page:

-O
Performs a device reset on the target altinst_rootvg. This causes
the alternate disk install to not retain any user-defined device
configurations. This flag is useful if the target disk or disks
become the rootvg of a different system (such as in the case of
logical partitioning or system disk swap).

When the disks containing this altinst_rootvg are moved to another host and then booted from, AIX will run cfgmgr and probe for any hardware, adding ODM information at that time.
