Advanced File system problem - Help appreciated

  Hello,
   OS = Tru64 4.0E

   I get the following error when I execute
   root#:/var/adm>showfdmn -k data_domain 
showfdmn: unable to get info for domain 'data_domain'
showfdmn: error = I/O error

    I see the following error in /var/adm/messages file 
    for this domain:

    Apr 22 18:04:59 psa014 vmunix: AdvFS I/O error:

   dikslabel -r rz1 works without error:

    can I use verify command for this problem? (verify data_domain#data?)
