Error description

  • After upgrading the Spectrum Protect server application version
    to 8.1.8.x from previous 8.1.x, the following type of errors
    are encountered after running " protect storagepool <local
    container pool> type=replserver "
    
    
    
    
    
    Date/Time Message
    
    
    ----------------------------------------------------------
    08/13/2019 06:53:54 ANR2088E An I/O error occurred while reading
    container /xxx/xxxxxx.dcf in storage pool
    08/13/2019 06:54:49 ANR2088E An I/O error occurred while reading
    container /xxx/xxxxxx.dcf in storage pool
    
    Checking those containers shows that all of them are in a
    pending state and were last written to a few minutes before the
    ANR2088E messages are issued
    
    The containers are successfully purged from the storage pool
    after the Reuse Delay has passed.
    
    The trace also shows the above and the dsmffdc.log shows the
    below :
    
    [ FFDC_GENERAL_SERVER_ERROR ]: (sdcntr.c:15501) Container moved
    under us, state = 3.
    
    
    Spectrum Protect Versions Affected:    Spectrum Protect server
    v8.1.x on all platforms
    
    
    
    Customer/L2 Diagnostics (If Applicable):
    
    The problem can happen if the source container pool is protected
    to both local copy container pool and remote replication server.
    In this case, the same container may be selected by both auto
    defragment and protection at the same time, which cause the I/O
    error later.
    
    Customer may run into  this APAR if below SQL returns more than
    one row:
    
    db2 "select * from tsmdb1.sd_replicated_stgpools where
    poolId=<source container pool Id>".
