Error description

  • In a replication environment, there are scenarios where orphaned
    chunks are created in container type storage pools on the
    target server. One such scenario is described by APAR IT14233.
    This APAR addresses the need for a new engine to automatically
    clean up orphaned chunks in container pools.
    
    Tivoli Storage Manager Versions Affected:
    IBM Spectrum Protect server 7.1.3 and later
    
    Customer/L2 Diagnostics
    The target container pool will use more space than the source
    container pool.
    The following DB2 command can be used to see if there are
    orphaned chunks (on the target server):
    db2 select poolname,poolid from ss_pools
    db2 "select sum(cast(length as bigint)) as sum, count as count
    from sd_chunk_locations cl where cl.poolid=<poolid> and
    (cl.chunkid, cl.poolid) in (select sdcl.chunkid, sdcl.poolid
    from sd_chunk_locations sdcl where refcount=1 and sdcl.chunkid
    not in (select sdro.chunkid from sd_recon_order sdro) and
    sdcl.chunkid not in (select sdrc.chunkid from
    sd_replicated_chunks sdrc) and sdcl.chunkid not in (select
    sdru.chunkid from sd_refcount_updates sdru) ) for read only with
    ur"
    
    Replace <poolid> with the container storage pool id.
    If the count returned is greater than 0, there are orphaned
    chunks in the storage pool.
