This post will describe how to create a bootable backup of the rootvg to another hdisk using the command alt_disk_copy. The command execution will be performed in 2 phases which are described below. The phase 1 and 3 are used in this example. There is also a possibility to use the phase 2 with alt_disk_copy where you can run your own customization sripts against the rootvg copy. For more information aks your good friend google.

Phase 1- Creates the altinst_rootvg VG, alt_ LV’s, /alt_inst file systems and restores rootvg to hdisk1.

                  Disk to backup to.
 # alt_disk_copy -d hdisk1 -P1
