Error description

  • During a backup or archive, a bus reset I/O error like the
    following may be detected:
    
    ANR8302E I/O error on drive DRVXX (/dev/IBMtapexx) with volume
     AXXXXX (OP=WRITE, Error Number=5, CC=0, rc = 2867, KEY= 06,
     ASC=29, ASCQ= 00, SENSE=71.00.06.00.00.00.00.58.00.00.00.00.
     29.00.F5.0A.C0.F0, Description=An undetermined error has
     occurred). Refer to the IBM Spectrum Protect documentation on
     I/O error code  descriptions.
    
    Here what the sense data means:
    Key= 06   "Unit Attention"
    ASC=29 , ASCQ=00  "Power-on, reset, bus reset"
    
    In such a situation, the write operation should stop and the
    affected volume should be marked as READONLY, but that does not
    happen here.
    
    
    Tivoli Storage Manager and IBM Spectrum Protect Versions
     Affected:  6.3 , 7.1  and 8.1 on Linux platform.

Local fix

  • - To remove any possible bad data, run "AUDIT VOLUME <volname>
      FIX=YES"  for all the volumes affected by the ANR8302E error.
    - Then backup the data again if the "AUDIT VOLUME" detected bad
      files.
