Hi,
Basically the server was down faulty hdisk0,corrupt hdisk1(Mirror of hdisk0)

Can get into Maintenance mode and run power on then not able to interrupt boot process ignore any key pressed to interrupt boot process carries on
to try to load software etc.

Get error code on display : IPLVARYON ERROR 0552.

Any help would be appreciated.

From the admin guide. Read it. It is your friend.

LED 552, 554, and 556 - Super block corrupted and corrupted customized ODM
database

Repeat steps 1 through 2 for LEDs 551, 555, and 557.

If fsck indicates that block 8 is corrupted, the super block for the file system is
corrupted and needs to be repaired. Enter the command:
dd count=1 bs=4k skip=31 seek=1 if=/dev/hdn of=/dev/hdn
where n is the number of the file system.

Rebuild your JFS log by using the command:
/usr/sbin/logform /dev/hd8

If this solves the problem, stop here; otherwise, continue with step 5.

Your ODM database is corrupted. Restart your system and follow the procedure
given in 4.4.2, �Accessing a system that will not boot� on page 105 to access rootvg
with choice 2 on the Volume Group Information screen.

Mount the root and usr file systems as follows:
mount /dev/hd4 /mnt
mount /usr

Copy the system configuration to a back up directory:
mkdir /mnt/etc/objrepos/backup
cp /mnt/etc/objrepos/Cu* /mnt/etc/objrepos/backup

Copy the configuration from the RAM file system as follows:
cp /etc/objrepos/Cu* /mnt/etc/objrepos

Unmount all file systems by using the umount all command.

Determine the boot disk by using the lslv -m hd5 command.

Save the clean ODM to the boot logical volume by using the command:
savebase -d/dev/hdiskn
where n is the disk number of the disk containing boot logical volume.

Reboot, if the system does not come up, and reinstall BOS.
