Measures reported by VNXeBatteryTest

A 3 - cell Lithium - Ion Battery Backup Unit (BBU) is located within each Storage Processor (SP) enclosure. The battery is designed to power systems long enough to flush the SP cache contents to an internal mSATA device in the case of a power failure or in the case of SP removal from the Disk Processor Enclosure (DPE). Atleast one BBU is required to be operating normally for SP cache to remain enabled. Therefore, it is necessary for the administrators to keep constant vigil on the health of the BBUs round the clock. The VNXeBatteryTest test helps administrators in this regard!

This test auto-discovers the battery backup unit of the target storage system and for each battery, reports the current health. Using this test, administrators may be alerted to batteries that failed/degraded and replace those batteries well before users identify any impact on the storage system.

Outputs of the test : One set of results for each battery of the target EMC VNXe Storage system being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
healthStatus Indicates the current health of this battery.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure value Numeric Value
Normal 0
Attention 1
Unknown 2
Degraded/Warning 3
Minor failure 4
Major failure 5
Critical failure 6
Non-recoverable error 7

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current health of this battery. The graph of this measure however is represented using the numeric equivalents only - 0 to 7.

The detailed diagnosis of this measure lists the owner of the storage processor, the slot, the health of the battery and the model of the storage system.
