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_at_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.
