Hi Guys i'm kinda desperate right now, I have an Ultra Sparc II with Solaris 8 but suddenly it start rebooting again and again by himself, after initialize memmory and starts booting, once the server displays the hostname it says that the server is coming down. and reboot all over again.

Any guess Will help.

Thanks.

Mikel.

My first guess would be that either the initdefault setting is wrong in /etc/inittab, or that there's a cron or at job doing it. I heard once that someone tried to use a cron job to reboot their machine, but the reboot caused the job not to finish successfully, so it kept rebooting.

If you can get into single user mode, you can check inittab and disable crond and atd.

Thanks Mcavic i type stop + A and then sync after that the server reboot again but i've got something like

/dev/rdsk/c0t0d0s0 FREE BLK COUNT(S) WRONG IN SUPERBLK (SALVAGED)

So it looks like it's a partition thing i don't know what to do does fsck fix that? and if yes what parameters do i need to type in fsck to fix it

Thanks again.

I'm not very familiar with Solaris, but that error is a result of an improper shutdown (or possibly a media error). A standard fsck on the partition should prompt you to fix any errors that it finds. I think the "salvaged" means that it did fix it. To fsck the root partition, though, you might be better off booting from a rescue disk if possible.

Thanks again but i have no recovery disk so i'm going to try to fix it, before i need to reinstall solaris.

In SCO Unix, you can run fsck on your current root partition (in single user mode), and if it fixes any errors it'll display a message telling you to power off immediately to preserve the fixes that it made. Solaris may be the same way.

The thing is that after the system does the sync and displays the error i type stop +A and at the ok promt type fsck but i get a:

fsck?

ok

from my solaris, so this means that i'm not able to run fsck?

thanks.
