Assume you have a software two-disk (hdisk0 and hdisk1) mirror of rootvg, and further assume that you are going to backup exec 2012 server 2000 agent do a ML (or application upgrade, assuming it is installed in rootvg) upgrade on this system.
# bootlist -m normal -o hdisk0 blvhd5 hdisk1 blvhd5 For this demonstration, that's it: mission accomplished.
The entries should start with the /.If the fix worked on (old_rootvg) hdisk0, then run with the new ML version.The basic format is: alt_rootvg_op -X cloned rootvg to destroy # alt_rootvg_op -X altinst_rootvg Bootlist is set to the boot disk: hdisk0 Next, avg tuneup 2011 trial extend rootvg to bring hdisk1, and then mirror up the disk: # extendvg -f rootvg hdisk1 # mirrorvg rootvg hdisk chvg: The.But what if the upgrade fails?
# bootlist -m normal hdisk0 Confirm the change of the bootlist: # bootlist -m normal -o hdisk0 blvhd5 Next, install the ML upgrade, then reboot.
Simply supply hdisk1 as a parameter to the command.
I will demonstrate one way this can be done to clone the disk and after a successful upgrade will bring the disk back into rootvg and re-mirror.
The alt command can also provide a path to a migration of a rootvg disk to another hardware.
