Measures reported by IbmStorwizeBattStsTest

Within a control enclosure, each power supply unit (PSU) contains a battery. The battery is designed to enable the IBM Storwize V7000 system to perform a memory dump of the cache to internal disks in the event of both power inputs failing. If these batteries are defective or have reached end-of-life, the storage system may be unsuccessful in writing cached data to the disks in the event of a power failure; this may result in loss of critical data. To avoid this, potential battery failures should be proactively detected and intimated to administrators, so that the problem can be fixed before any data loss occurs. This is where the IbmStorwizeBattStsTest test helps.

For each battery in the PSUs, this test reports the battery health, whether it has adequate charge or not, and whether/not it is reaching its end-of-life. This way, the test warns administrators of an impending battery failure, and enables them to take pre-emptive action to correct the issue.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
status Indicates the current health status of this battery.   This measure can report any of the following values:

  • offline
  • online
  • degraded

    • The numeric values that correspond to the above-mentioned measure values are as follows:

    Measure Value Numeric Value Description
    offline 0 The battery could not be detected.
    online 1 The battery is present and working as usual.
    degraded 2 The battery is present but not working as usual.

    Note:

    By default, this measure reports the above-mentioned Measure Values while indicating the status of this battery. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.
    charging_status Indicates the charging status of this battery.   This measure can report any of the following values:

  • Idle
  • charging
  • discharging

    • The numeric values that correspond to the above-mentioned measure values are as follows:

    Measure Value Numeric Value Description
    Idle 0 The battery is neither charging nor discharging.
    charging 1 The battery is charging.
    discharging 2 The battery is discharging at present.

    Note:

    By default, this measure reports the above-mentioned Measure Values while indicating the charging status of this battery. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.
    recondition_needed Indicates whether this battery needs to be reconditioned or not.   This measure indicates a value Yes if the battery needs to be reconditioned and a value No if the battery requires reconditioning, but cannot be reconditioned due to one or more errors.

    The numeric equivalents of these values are mentioned in the table below:

    Measure Value Numeric Value
    No 0
    Yes 1
    Note:

    By default, this measure reports the above-mentioned Measure Values while indicating the reconditioning status of this battery. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.
    percent_charged Indicates the current charge percentage of this battery. Number A high value is desired for this measure. A value close to 100% could indicate that the battery charge is about to die.
    end_of_life_warning Indicates whether this battery is reaching its end of life warning and needs to be replaced or not.   This measure indicates a value Yes if the battery is reaching its end of life and a value No if otherwise.

    The numeric equivalents of these values are mentioned in the table below:

    State Numeric Value
    No 0
    Yes 1
    Note:

    By default, this measure reports the above-mentioned Measure Values while indicating whether this battery is reaching its end of life or not. However, in the graph of this measure, the same will be represented using the corresponding numeric only.
