Replacing mirror root drive

[bagek]

I have a rp5470 running 11.23. one of the root drives has failed. has anything changed since the doc "when good drives go bad" came out? here is what is what i did years ago

Replace failing drive online then . 

  # vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t0d0
  # mkboot /dev/rdsk/c2t0d0
  # mkboot -a  "hpux(;0)/stand/vmunix"  /dev/rdsk/c2t0d0

  # vgchange -a y /dev/vg00

  # vgsync /dev/vg00 

this works on my test rp7410 box running 11.11

Thanks

I see no reason to shut the system down.

You should be able to replace the drive, then start at the vgcfgrestore step and proceed.

If you patched your system within the last 5 or 6 years you should have the command

# pvchange -a n ...

available. So you can do a real online replacement according to the manual.

Replace failing drive online then . 

  # vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t0d0
  # mkboot /dev/rdsk/c2t0d0
  # mkboot -a  "hpux(;0)/stand/vmunix"  /dev/rdsk/c2t0d0

  # vgchange -a y /dev/vg00

  # vgsync /dev/vg00 

this works on my test rp7410 box running 11.11

should i be using this? i found it on an HP blog. ehat's the difference? thanks. 

#vgcfgrestore -n vg00 /dev/rdsk/c2t0d0 

#pvchange -a /dev/dsk/c2t0d0

#vchange -a y dev/dsk/c2t0d0

#mkboot /dev/rdsk/c2t0d0

#mkboot /-a "hpux" /dev/rdsk/c2t0d0

You should use this, nothing else:

Without doing "pvchange -a n ..." the command "vgcfgrestore ..." will fail!
