Unisphere for PowerMax 9.2 Snapshot Policies

  • The method for scheduling recurring snapshots that was introduced in Unisphere for VMAX 8.3 is being deprecated in Unisphere for PowerMax 9.2 in favor of Snapshot Policies.

    When upgrading to Unisphere for PowerMax 9.2, snapshot schedules that were created with previous versions of Unisphere continue to run as scheduled. However, the snapshots cannot be modified other than being deleted, and new schedules cannot be created using the legacy method.

    Do not assign an SG to snapshot policies and legacy snapshot schedules simultaneously. In general, delete legacy schedules and end their snapshots before assigning the SG to a policy.

    However, the legacy schedules and snapshots can remain if required to support business cases as snapshot policies are implemented and approach compliance. Use care to ensure that system resources are not exhausted, including ensuring the automatic expiration date is set on the snapshots.

    The following information is for environments that are unable to upgrade to the PowerMaxOS Q3 2020 release.
