x86 server not booting

hello,

We had a power outtage and took down our 2 Sun x2100 server, running S10 x86 06/06.

one of them,when poweron, it stopped with "panic no entry point in kernel/amd64/unix.
The other one requested to run svcadm clear system/boot-archive, but after ran that command, it can't boot into multi-user mode, is the brub gets corrupted?

reboot server can not bring it back on line.

Any help is greatly appreciated,

SOunds like you may need to repair the boot MBR or partition.

Can you use a repair CD TO JUST FIX BOOT RECORD? PROGRAM ?

Have you contacted SUN ?


I hope this helps !

You the Solaris Software CD (first disk) to boot up to single user mode.

run fsck to all filesystem  (raw device please)
eg:

fsck -y /dev/rdsk/c0t0d0s0

PS: For Solaris x86, the device name looks like
      /dev/rdsk/c0d0s0
do the same thing to both box.

If you still have problem, try to use the CD to boot uo to single usr mode, and repair the boot record

eg
do "installboot" to /dev/rdsk/c0d0s0

installbot /usr/platform/`uname -i`/lib/fs/ufs/bootblk  /dev/rdsk/c0d0s0

I exactly ran into this problem yesterday.

Boot into the failsafe mode and I'm sure you will be promted  withe a YES/NO question about the inconsistent cache on the boot-archive. Select Yes to fix the problem.

If it fails, proceeed into the failsafe mode and mount root_vol to /a , then run

#/sbin/bootadm update-archive -vR /a

This should help.

Ring sun and make them to look at

boot with the cd and run in single user mode. and follow the procedure to fix the bootblk

if not there is a Diagnostic cd  for x2100 which you can run to check for any hardware failure(like disk)

paste the excat error you encouterr while you running the fsck or repairing the bootblk


hope this helps
