I dont have either a tape drive or a DVD Writer attached to the AIX box. Can you let me know the possibilities of making an mksysb in a bootable media? This is required as we have a requirement to upgrade the OS.
With neither tape or DVD you cannot create bootable mksysb. However you could create a mksysb on an NFS attached disk which although not bootable would enable a restore if the upgrade fails. This would invole loading the O/S on ROOTVG and restoring the mksysb image afterwards.
If you have another machine, you could configure that as a nim server and keep the mksysb there to re-image the server.
Or if it is just for the upgrade, you could break the rootvg mirror and do an alt_disk_copy to update the free disk with the latest OS and boot through it.
