Symptoms

Products:

  • PowerMax 8500
  • PowerMax 2500
  • VMAX4

Feature:

  • LREP

Software:

  • PowerMaxOS 10.0.X.X
  • PowerMaxOS 10.1.0.1

Error codes:

Error code: 82.3F10.12 - SDMA Locate Failure

Error code: xx3C.14

Error code: 423E.14

Cause

The RSVD Node always indicates the latest version of the track for a device involved in LREP. When there is a write to a track involving LREP, and we must push the old data to RDP.

The TID SEQ# is updated to match the Device Seq# and the old RSVD Node is pushed to RDP. A new RSVD node is assigned with the same Seq#. Therefore, the RSVD Node Seq# should always match the TID Seq# and we should only have one RSVD Node for a track.

The 3F10.12 error occurs when the RSVD node SEQ# does not match the TID SEQ#. We have seen cases where the RSVD node SEQ# is greater or less than the TID SEQ#.

Resolution

The issue is planned to be addressed in a future hotfix that is available from Q1 24 patch release. Contact Dell Technical Support or your service representative and mention this article ID for assistance.
