Hello,
I have a AS2000 running 4.0g PK3, 512 MB memory, 2 300Mhz CPU's
Last week I had this system crash. During the initial nightly backup one
of the tape drives gave a error (something about R/W errors or lost
contact with the tape)
There are 2 backup processes running at the same time, and have been for
years. Each backup goes to different tapes.
The bigger backup completely fine. The smaller one (about 2 GB) did not
complete.
I had the operator try to remove the special files in /dev for that tape
and then recreate them.
The recreate failed due to errors (device not found)
I tried to scan the Scsi bus with scu show edt
but it also gave device not found
When the big backup was done I had the operator reboot the system. It
failed at this point.
vm_swap_init vm_swapon for /dev/rz0g device failed.
The next step was to start the second processor and then rescan the bus
to get things working into multiuser mode.
I couldn't boot into single user mode.
After a few hours trying to get things working basically I reformated
the swap space on rz0g and the /tmp directory on rz0h.
I also put in a new hard drive into the system, restored the /root
filesystem and the /usr filesystem.
Then things went fine.
Monday the system wasn't ready either. Every sunday is an automatic
reboot. That was my fault. I had a error in my fstab file.
Last night I (and hardware tech from HP) put in my secondary scsi
controller, (one of the items I had taken out last week. the screw
holding it was broke and the card was not in the pci slot at all, it is
a wonder that it worked)
When I tried to reboot the system would not boot. It was missing the
osf_boot file.
This morning one of my advfs domains wasn't mounted. There wasn't
anything on it (the programmers just use it for nightly processing) so
after trying verify and advscan it would not mount.
I recreated it and the fileset and then mounted it.
Any idea what to look for??
Have I been hacked??
What do I need to do?
Many thanks.
