LEDs stuck at 553, 552, 551

[luis basto]

There has been a number of reports on boot problems resulting in
LEDs 553, 552, and 551. The following steps may help save you some time.


LED 553 - causes: / or /tmp too full; inittab got corrupted

1) Go into install/maintenance mode by booting from boot diskette
   or tape with the key in service position
   Note: If using diskettes, all three (boot, console, install/maint)
         must be loaded

2) Select option five on menu for install/maintenance. You'll get prompt.

3) Type '/etc/continue hdisk0'. This will take a minute or so to run.

4) Type Ctrl-D to exit current shell                

5) umount /dev/hd2                                     
   umount /dev/hd3                                     

6) chroot /mnt /bin/ksh                            

7) mount /dev/hd2 /usr                                  
   mount /dev/hd3 /tmp                                  

8) bosboot -a
   shutdown -Fr

   Remember to move key back to normal position.

This procedure also works if LEDs were stuck at 201 while booting.


If your / or /tmp were too full, delete something to recover space. Usually
smit.log and smit.script on / are enough to get the system back to normal.

If your inittab is corrupted it may sometimes be easier just typing
it back in unless you have saved a handy copy on diskette. Here's a
basic inittab file for starters.

: @(#)inittab	1.22  com/cfg/etc,3.1,9021 4/6/90 17:18:07
init:2:initdefault:
brc::sysinit:/etc/brc >/dev/console 2>&1 # Phase 2 of system boot
rc:2:wait:/etc/rc > /dev/console 2>&1    # Multi-User checks

rctcpip:2:wait:/etc/rc.tcpip > /dev/console 2>&1 # Start TCP/IP daemons
rcnfs:2:wait:/etc/rc.nfs > /dev/console 2>&1     # Start NFS Daemons

LED 552 - causes: multiple; cannot varyon root volume group

1) Go into install/maintenance mode by booting from boot diskette
   or tape with the key in service position
   Note: If using diskettes, all three (boot, console, install/maint)
         must be loaded

2) Select option five on menu for install/maintenance. You'll get prompt.

3) Type '/etc/continue hdisk0'. This will take a minute or so to run.

4) If no error messages, then 
       savebase
       sync;sync
       shutdown -Fr

5) If error messages, then
       /etc/aix/logform  /dev/hd8
       shutdown -Fr

   Remember to move key back to normal position.

LED 551 - causes: unknown; cannot varyon root volume group

Sorry, this is under investigation. Re-install system.
