25 Jul 13 Replacing a bad vxvm boot disk. HP-UX 11.23 PA-RISC

So you lose a boot disk on a vxvm booted system. You hot replace the disk, but now you need to make sure the software mirror is good.

 

Lets say for example its rootdisk02

If the disk stayed alive and did not power down you can run vxbrk_rootmirror and cleanly replace the disk.

What do do if the disk powered down?

/opt/VRTS/bin/vxdiskunsetup -C rootdisk02

vxrecover -g rootdg -sb

You more than likely end up with a disk named like this that is totally useless:

rootdg.26724.31359

vxdg destroy rootdg.26724.31359  (on rootdisk02)

 

Remove the incomplete mirror copy

 

/etc/vx/bin/vxbrk_rootmir -v rootdisk02

 

And mirror it back ,

/opt/VRTS/bin/vxrootmir -v -g rootdg rootdisk02
