Hello,
My original message is attached bellow. I thought I had a problem on
a SCSI controller but actually it was an error on a disk. Many people
suggested me that the disk was bad and that I had to replace it but the
real problem was a single bad block on the /usr partition. I booted on
single user mode, I used scu(8) utility:
/sbin/scu -f /dev/rdisk/dsk1g
to find the bad blocks (verify scu command) and then reassign that
blocks (reassign scu command). Then I verified again and no blocks were
bad. Then I restarted and everything now is fine (well perhaps the
reassigned block will provoke a future problem but minor I would think).
I owe this solution to Alan Rollow <alan@desdra.cxo.cpqcorp.net>
but I thanks to all the people that replied me quickly and gently:

Hello Managers,
Due to a power failure an alphaserver 4100 with tru64 unix 5.1 is
not booting anymore. When it arrives to the moment of mounting /usr
(this is an advfs filesystem in the usr_domain) it displays a lot of
messages of error, including these ones:
cam_logger: SCSI event packet
cam_logger: bus 1 target 0 lun 0
...
...
DEC RZ1CB-CA (C) DECLYJ0
Active CCB a time of error
CCB request completed with an error
Error, abnormal or exception
MEDIUM ERROR: unrecoverable
...
...
PANIC ADVFS filesystem...
...
Well, I would like to know if these is actually a hardware problem?
AFAIK RZ1CB-CA is a SCSI controller, is this correct? can I fix it or
should I replace it?
Any help will be very appreciated.
