Abstract

When QoS is enabled on XIV Gen2 and Gen3 systems, the interface node (i_node) may encounter a failure whenever the module uptime is multiple of 497 days (i.e 497, 994, 1491, etc).
If the defect occurs on multiple XIV interface modules at the same time, this could cause Loss of Access.

Affected versions and fix

  1. Gen2 – 10.2.4 and later releases
  2. All Gen3 systems 11.x.x

As the defect relates to the QoS feature, the QoS Performance Classes and assigned hosts need to be disabled BEFORE the uptime reaches 497 days (or multiples of this number).
Until the permanent fix will be available for the affected versions, this counter can be reset via the following procedure:

  1. Disable QoS
  2. Patch Management (PMS) script to be applied by IBM personnel…
