After adding an external SCSI controller, cartridge tape, and 600m disk, then doing the 3003 update, my system is not happy. It fails to boot with '551' on the LED. I got some hints from my SE about why this is happening, but unfortunately the last resort - rebuilding the system - is not an option, because the thing won't even boot from tape. I am about to start loading diagnostics from floppy, but I thought that by the time that happens, somebody else might be able to give me more clues. Please. rob -- -------------------------------------------------------------------------------- "Unix has its weak points, but its file system is not one of them." -Chris Torek rob rob@dinner.asrc.albany.edu or rds95@leah.albany.edu I have no idea what the uucp path to me is.

Please. > An associate passed me the following information: + The following are related LED read-outs concerning the first phase + of IPL. + 551 - rootvg is being varied on (phase 1 of IPL) + 552 - varyon of rootvg failed + 553 - IPL phase 1 completed + Although LED 551 means that the system is in phase 1 of IPL and LED + 552 is the one that actually reports a problem while in this phase, + sometimes the system only reports LED 551 then hangs up before it ever + gets to display the 552 message. Therefore, an LED 551 or 552 means + that the system is unable to varyon the rootvg because it was + corrupted. + LED 552 means that the varyon of root volume group has failed and + it is suspected that the file systems may be corrupted and the system + is not sending the appropriate signals to the init command. Defect + Support suggested doing the following: + 1.a) Boot off diskette/tape in service position. + b) Run "/etc/continue hkisk0". + c) If errors occurs, something is corrupted. + d) Run "/etc/aix/logform /dev/hd8" and then reboot the system in + the normal mode. + e) If you get the message "/dev/hd8 not found", then go on to 2. + 2.a) Disconnect the system battery and turn off the power for about + 20-30 minutes, then reboot the system. This can clear out the + problem caused by corrupted NVRAM. + 3.a) If neither suggestions worked, you need to have the system + reinstalled. Hope this helps.
