Solution 2047315.1 : FS System: Drive Enclosure Power Supply Remains Critical in GUI After Replacement or Power Outage

Applies to:

Oracle FS1-2 Flash Storage System - Version 6.1 to 6.2 [Release 6.1 to 6.2]
Information in this document applies to any platform.

Symptoms

Drive Enclosure Power Supply shows "critical" in GUI, but physical examination yields no problem.

Event logs will show the following information.

2015-07-30T14:48:49.515 RAID_EVENT_ENCLOSURE_POWER_SUPPLY_STATUS_CRITICAL CRITICAL ComponentName=/ENCLOSURE-01, Source=/CONTROLLER-02, cruId=CRU_PSU0
2015-07-30T14:48:49.775 RAID_EVENT_ENCLOSURE_POWER_SUPPLY_STATUS_CRITICAL CRITICAL ComponentName=/ENCLOSURE-01, Source=/CONTROLLER-01, cruId=CRU_PSU0

Changes

Drive Enclosure Power Supply was just replaced or power cycled.

Cause

When a Drive Enclosure Power Supply is replaced or powered off/on faster than 15-20 seconds.

Solution

Make sure to identify the proper Power Supply. The back of the Drive Enclosure Power Supply has a map like this.

DE_Power_Supply

Possible Power Supplies will be PSU0, PSU1, PSU2, PSU3, depending on if it is a 2U or 4U Drive Enclosure. The GUI should also indicate which Power Supply is affected.

Temporary workaround: Disconnect the power cable or power off via switch on Drive Enclosure Power Supply in question (only if both are physically working and one at a time), wait at least 20 seconds before re-connecting power cord/powering back on. If this does not work or is not an option, the other method is to perform a Pilot failover from FSCLI as user "pillar". The default pillar password is "a1s2d3f$".

# fscli.exe login -u pillar -oracleFS <FS ip or name>

# fscli.exe pilot -forceFailover

The GUI should now show the Drive Enclosure Power Supply as normal if the Power Supply is physically ok, otherwise there may be a legitimate issue with it.

This issue has been resolved in software release 6.2.x and above.
