If the pool capacity (or the capacity ensured for writing) exceeded the threshold, a pool was blocked, or there is no free space in shared memory, Service Information Messages (SIMs) below are issued. This topic provides information about SIMs related to Thin Image pools. For SIMs related to DP pools, and for details about the pool usage capacity and the capacity ensured for writing, see the Provisioning Guide for your storage system.

Fix pool-related errors by referencing the following Service Information Messages (SIMs):

  • Reference code 604xxx or 606xxx: The pool usage rate of capacity (or the capacity ensured for writing) exceeds the threshold.
  • Reference code 602xxx or 605xxx: The pool is blocked.
  • Reference code 602ffe: Multiple pools are blocked.
  • Reference code 603000: The Snapshot Estimated Manageable Capacity for HTI pairs or the estimated configurable capacity (which indicates the size of V-VOLs you can create) for HTI Advanced pairs meets either of the following conditions:
    • Reached less than 5% of the capacity supported by the installed shared memory.
    • Remains less than 5% of the capacity supported by the installed shared memory even after 8 hours since the output of reference code 603000.
  • Reference code 624000: You have reached capacity in the shared memory.

xxx indicates the pool ID. For details about reference codes of SIMs, contact customer support.

For VSP 5000 series, you can check the SIMs occurring in storage systems from a Device Manager - Storage Navigator window. For information about the Device Manager - Storage Navigator windows you can use for checking SIMs, see the Provisioning Guide for your storage system.

Use the following workflow to implement fixes:

  1. Complete one of the following:
    For reference code 602xxx, 604xxx, 605xxx, 606xxx, or 602ffe
    Recover the pool ("Normal" status).
    For more information about the countermeasures to take when the pool capacity (or the capacity ensured for writing) exceeds the threshold and when a pool was blocked, see Workflow for correcting pool-related failures (SIM = 602xxx, 604xxx, 605xxx, and 606xxx).
    For reference code 624000
    Complete one of the following:
    • Delete unused pools
    • Delete unused Thin Image pairs
    • Delete unused DP-VOLs, V-VOLs with capacity saving enabled, or DRS-VOLs
    • Shrink the capacity of the HDP pool, HDT pool, active flash pool, or HTI pool.
    For reference code 603000
    Perform one of the tasks listed for reference code 624000 above. Although task completion is not a requirement, if it is not completed some time after reference code 603000 was issued, then reference code 624000 might be reported. In Device Manager - Storage Navigator, enabling the Disable the alert notification of shared memory space warning option in the Edit Local Replica Options window or using the raidcom modify local_replica_opt -set_system_opt command in CCI to set ID# 30, inhibits the alarm notification of reference code 603000.
  2. (VSP 5000 series) Clear the SIM from the storage system. Depending on the SIM's reference code, one of the following occurs:
    • The SIM is automatically completed.
    • You manually complete the SIM.
  3. (Optional) Use HDvM - SN to confirm that the SIM completed normally.
