Boot to led 223

Question:

Env:
  AIX 3.2.5
  RISC 7015-R24
  2.2gb disk

Desc:
  Customer's system is booted to a led 223, after the customer
  did a shutdown -F, then powered the system off for
  a little while.

Action:
  1.  Booted from a mksysb tape.
  2.  getrootfs hdisk0 
        It did not find hdisk0 at all
  3.  Called Hard Ware support (800) 426-7378
      The customer had a sticksion problem, which the CE fixed.
      When the customer rebooted the system it hung on led 555

  5.  Booted from a mksysb tape.
  6.  getrootfs hdisk0 sh
      hdisk0 now shows in a removed state with the rootvg
      We need to run the lchangepv command to include it back
      with rootvg.  Most likely it ended in this state when the
      sticksion problem occurred.  Since the system could not
      access the drive the system set the drive in a removed 
      state.

  7.  Since the lchangepv command is not part of the ram filesystem
      we will need to restore it from the mksysb tape.

      a.  tctl -f /dev/rmt0 rewind
      b.  tctl -f /dev/rmt0.1 fsf 1
      c.  restbyname -xvqf /dev/rmt0.1 ./tapeblksz
      d.  cat tapeblksz
            value is 1024
      e.  /etc/methods/chggen -l rmt0 -a block_size=1024
      f.  tctl -f /dev/rmt0 rewind
      g.  tctl -f /dev/rmt0.1 fsf 3
      h.  pax -rnvf /dev/rmt0 -pmop ./usr/sbin/lchangepv

   8. lqueryvg -Atp hdisk0
      Get vgid  (under the logical part)
      00002144E06D20DA
      Get pvid  (under phsysical)  First one)
      000021442AC090 (I think)
   
  9.  lchangepv -g vgid -p pvid -r2
  10.  exit
  11.  bosboot -ad /dev/hdisk0
  12.  turn key to normal mode and reboot

System booted to normal mode

Next Action:
  Closing with customer approval
