AdvFS problems

I'm having problems on a fileserver, Digital Unix 4.0E on an
Alphaserver 2100. Started Sunday in the early morning hours, happened
again twice Monday night/Tuesday morning. Many errors similar to the
following:

  vmunix: AdvFS I/O error:
  vmunix: Volume: /dev/rz16c
  vmunix: Tag: 0xfffffffa.0000
  vmunix: Page: 8404
  vmunix: Block: 147088
  vmunix: Block count: 16
  vmunix: Type of operation: Read
  vmunix: Error: 5

The volume, page and block vary but repeat; all are error 5 and nearly
all the operations are read. The three volumes are members of the
same domain (but all domains effectively become inaccessible).

Is this likely a disk hardware problem? Perhaps the domain needs to
be rebuilt? Any advice welcome.
