p630 not booting stuck at AIX is starting

[hellsbells]

Has anyone ever come across a problem with AIX not booting.

I had a problem with a SAN and there was a filesystem mounted via fibre. I have exported the vg and the odm no longer knows a thing about the vg, however, the server will not boot.

I have tried all manner of things - from recreating the boot image (bosboot -ad etc), booting from both hdisk0 and hdisk1, removing the fibre cable from the internal card, and installing an IBM fix which was thought to be relevant IY57153. None of these worked.

Does anyone have any experience of this or can you give me any guidance as to what else I should try?

Many thanks

What's the status of the LED?

 

[hellsbells]

It is running AIX 5.2 and the LED says AIX is starting

The console screen is simply stuck at closing stdin and stdout.........

Are thee any errors in errpt or if you run diagnostics do any errors show up . Are there any errors referencing the fibre card.

Was there any other disks connected to the Fibre card apart from the VG you exported .

IF you go to the shell from OS Cd or diagnsotics CD can you mount all filesystems successfully ?

 

[hellsbells]

Yes - when you go into maintenance mode you can import rootvg and mount all filesystems successfully.

There were adapter errors in errpt, but there are no other filesystems which are mounted on the SAN disks.

There are no other errors in errpt other than the adapter errors. I was wondering whether I should actually physically remove the adapter from the server.

Are you able to go in maintenance mode?

Disconnect all external Fibre cables and try again.

[hellsbells]

Yes - already tried this - there are currently no fibre cables attached whatsoever.

 

[aixnag]

While in maintenance mode,
do check on bosboot and bootlist.
Disconnect external Fibre calbes. Run diagnostics to confirm the adapter errors.
If you are authorized to remove the card, why not, remove them and test it.

Have you got anything in the startup scripts which makes a connection to a remote server i.e. NFS running , if so disable it

 

[hellsbells]

I have now removed the fibre adapter - this still did not work.

I have also checked and there is nothing in /etc/inittab relating to any nfs services.

I am really stuck now...........!

 

[MoreFeo]

Have you checked /etc/filesystems? If there's any nfs filesystem check that there's no 'hard' option. If any, change it to 'soft'.

 

[hellsbells]

All I have in /etc/filesystems are locally mounted filesystems which are included in the rootvg - ie:

/
/home
/usr
/var
/tmp
/proc
/opt
/cdrom
/u01
/u02

None of these are nfs mounts.

 

[DSMARWAY]

when your server boots , what if any is the value on the LCD display before you get the message AIX starting

The last one is 9117...........

Take a look at this doc

Unix *is* user friendly. It's just selective about who its friends are.

hi ,


o.k checked the service guide for p630 ( following is from the pdf , it may be worth a try ..., long shot )




9117 Start system IPL program See note 1 on page 167.



Notes:
1. If the system fails to progress after this checkpoint is put in the display, do the following:
a. Activate the service processor pinhole reset switch on the system’s operator panel.
b. If the hang repeats, check with service support to see if there is a firmware update that fixes the
problem.
c. If not, or the update does not fix the problem, replace the CEC backplane, location: U0.1-P1.
d. If this procedure does not fix the problem, call service support.
2. If the system fails to progress after this checkpoint is put in the operator display, do the following:

when in maint mode before mounting rootvg did you fsck the lv then do s /usr/sbin/logform /dev/hd8 answer y
mount rootvg, verify hd id on boot disk (lslv -m hd5) if correct do bosboot -ad /dev/ipldevice then check bootlist, sync;sync;sync;shutdown -Fr
