Symptoms
This is a warning alert that is generated when multiple disks in the pool have predicted an End of Life (EOL) less than 30 days.The alert will display a more specific number of days remaining for disks in the pool and all disks could have different number of days remaining for EOL, so the alert message displays a range.The health bubble message will have only "less than 30 days remaining" text. Log message text:Pool A has X drives predicted to exceed end-of-life thresholds within Z days.Pool A has X drives predicted to exceed end-of-life thresholds within Y to Z days.
Cause
There is both an OE code and drive firmware issue that causes the premature reporting and EOL of drives with the part numbers listed in this KB.Affected part numbers (TLA):005052155005052154005052379005052380005051740005051739005052377005052378
Resolution
For the above part numbers on a Unity array, DO NOT replace any drives proactively, as this is a premature failure indicator.This also includes the drives that have already reached EOL and are currently faulted or disabled.Dell EMC support can re-enable the drives by clearing the EOL flag with software commands.Please contact Dell EMC Technical Support or your Authorized Service Representative, and quote this Knowledgebase article ID.Newer Unity OE as well as drive firmware has been released to address premature wearing of the TLA drives listed above. The new OE code and drive firmware should be applied as soon as possible to prevent any additional premature wear reports. Please note that Unity OE 5.0.1 still will need to be applied to have the Days Remaining recalculated to reflect accurately. So the following Unity OE and drive firmware should be installed:
Latest Drive Firmware Package (This issue is fixed since "Unity_Drive_Firmware_Package-V11", so install v11 or later)Unity OE: 5.0.1 or later
If a drive that reaches EOL and/or 0 days is not part of the affected TLA list below, the drive should be replaced using the normal procedure.For more information about how to safely replace a faulted or EOL drive that is part of a dynamic pool, please refer to article 000019760.

For multiple drive EOL reports for part number other than the ones listed above, and before taking any action, please contact Dell EMC Technical Support or your Authorized Service Representative, and quote this Knowledgebase article ID.
