HPE StoreVirtual 3200 - The Storage System Powers down before Completing Switchover to UPS Backup System; Faulty Cache or Faulty Battery Alarm Displays

• RAID has been configured
• A management group has not been created yet
• One of the storage controllers fails
Action
You can ignore the information; the system will work as designed. The issue corrects itself once the failed
controller is replaced.
The storage system powers down before completing
switchover to UPS backup system
Symptom
On HPE StoreVirtual 3200 Storage systems configured with a UPS backup system, the storage system
might power down before completing the switchover to the UPS backup systems.
Cause
Due to the power monitoring characteristics of the StoreVirtual Storage system power supplies, storage
systems might detect failing AC power and initiate a shutdown before the switchover to the UPS backup
system completes.
The switchover time required by the StoreVirtual 3000 Storage power supplies is less than ½-cycle (8.3
ms). If the UPS system takes longer than ½-cycle (8.3 ms) to switch over, the storage system recognizes
a loss of power and initiates a graceful shutdown to preserve the I/O data currently in process.
Action
Verify that your HPE StoreVirtual 3200 Storage system is compatible with your UPS backup system. The
UPS backup system must be able to complete a switchover from main power in less than ½-cycle (8.3
ms). Hewlett Packard Enterprise supports the use of any online or double-conversion UPS with the
StoreVirtual 3200 Storage. Avoid offline, standby, or line-interactive UPS implementations. These devices
might not be able to switch over from the primary power source to the secondary power source fast
enough to ensure continuous power to the StoreVirtual 3200 Storage.
Faulty cache or faulty battery alarm displays
Symptom
When cache system is disabled, the StoreVirtual Management Console (SVMC) might display alarms for
a faulty cache, a faulty battery, or degraded RAID status.
Solution 1
Cause
When a battery or cache system has failed, a battery is charging, or a battery is undergoing maintenance,
the cache systems on both controllers are disabled to ensure data integrity. When both cache systems
are disabled, the SVMC displays faulty battery or faulty cache alarms for both controllers, even though
only one controller is charging or has failed. The SVMC may also display degraded RAID status alarms
due to the disabled cache.
