Subject: Problems after power off! Help!

   Hi Sun Managers!

   I have a problem: Yesterday, power went off in our building and a
Sparc Server 2 with Solaris 2.3 that we have was not protected by a
no-break, so it went off. Today, when i try to boot it, it just stops after
issuing the message "starting syslog services". It just stays there! I went
to my computer and i was able to do a telnet to that computer, but it seems
that something with a strange process is happening: I took a look at
/etc/rc2.d and saw that the file that issues that message (syslog ...)
was S74syslog. The next file to be executed by the boot process is
S75cron. I did a sh S75cron and got no response. It just stayed there
without any messages. The first thing that file executes is a ps, so i
did a ps -ef in the computer. No answear at all. Then i tried a ps -fu
root. Still no answear. I did a vmstat 3 and got the following:

 procs memory page disk faults cpu

   As you can see, something very strange is going on! Nobody, but me, is in
that computer. How come it says that CPU has idle time of 0? What do yo
think about the sy column? I need this server for NFS, but it seems like
pcnfsd is not running, since i cannot mount filesystems to my pc's. I got
this same problem in the past with an IPX with solaris 2.3, and i had to
reinstall Solaris since i needed that computer at the moment. Any ideas?
I'll summarize.

Thanks a lot!

I took a look at my system very closely, rebooting several times with
the -r option, and, giving myself up, i finally attached the cdrom to
my server in order to reinstall the system, but i gived it a last
chance: I did boot -rs with the cdrom attached. At that moment, i saw an
error on the console: "Cannot read bd.off link". I took a look at some
other of my servers and saw that /dev/bd.off should be a link to
/dev/term/b. In my crashed system, it was pointing to nothing! I deleted
the link and recreated it. That was it. Now, would someone be so generous
as to tell me what the .... does /dev/bd.off is used for?

Thanks!
