Error description

  • Problem Description:
    REPAIR STGPOOL may not repair all extents in directory-container
    pools, despite claiming to have done so. After running REPAIR
    STGPOOL to repair damaged data in a directory container storage
    pool, the data remains unrestorable. In addition, QUERY DAMAGED
    will not show any damaged extents, files, nodes or containers in
    the pool.
    
    Customer/L2 Diagnostics:
    Search the activity log to determine if REPAIR STGPOOL was run.
    Use the following db2 query on the source server to find out if
    damaged extents remain in the pool:
    
    select 1 from tsmdb1.sd_chunk_locations sdcl inner join
    tsmdb1.sd_replicated_chunks sdrc on (sdcl.poolid=sdrc.poolid and
    sdcl.chunkid=sdrc.chunkid) where sdcl.poolid=XXXX and
    sdrc.chunktype=0 and bitand(sdcl.flags,1)=1 fetch first row only
    for ur
    
    select 1 from tsmdb1.sd_non_dedup_locations sdndl inner join
    tsmdb1.sd_replicated_chunks sdrc on (sdndl.poolid=sdrc.poolid
    and sdndl.chunkid=sdrc.chunkid) where sdndl.poolid=XXXX and and
    sdrc.chunktype=1 and bitand(sdndl.flags,1)=1 fetch first row
    only for ur
    
    These queries will identify if there are still extents that are
    damaged, although they protected to a target server. Run these
    queries for each directory-container pool on the source server
    that has had Protect Stgpool run, and this issue is suspected.
    Use SHOW SDPOOL and and make note of the poolids for each
    suspected pool. Replace "XXXX" in the queries with this number
    and repeat for each pool individually. If either query results
    in a return of 1 record, this APAR is in effect for that pool.

    * RECOMMENDATION:                                              *
    * Apply fixing level when available. After applying fixing     *
    * level, run REPAIR STGPOOL twice. The first time REPAIR       *
    * STGPOOL is run, it will make a one time repair of database   *
    * entries that will allow the second repair to succeed. It     *
    * will appear to do nothing, yet it will report that it ended  *
    * in SUCCESS. This problem is projected to be fixed in 7.1.6.  *
    * Note that this is subject to change at the discretion of     *
    * IBM.                                                         *
