About this task
Health check performs the following tests:
- Vault State Test—Verifies the ability of the system to save data if there is a power failure.
- Spare Drives Test—Verifies that spare drives are available if there is a drive failure.
NOTE: In Unisphere release 9.2.1 where a spare drive has been invoked, Unisphere provides an additional message in the Health Check dialog if the Spare Drives Test fails. The message states that the storage system is almost out of spare drives and that support will be in contact.
- Memory Test—Verifies that the memory is reporting no errors or disabled banks.
- Locks Test—Verifies that there are no software locks present.
- Emulations Test—Verifies that all directors are loaded with the same Enginuity release as the release on the service processor.
- Environmentals Test—Verifies that internal environmental components (power supplies, fans, batteries, and so on) are reporting no errors.
- Battery Test—Verifies that the most-recent battery test reported no errors.
- General Test—Checks for any abnormal conditions in the following areas: Volume status, director status, stalled upgrade, code table integrity, directors running same code.
- DARE Test—Verifies that the most-recent DARE test reported no errors.
NOTE: If DARE is enabled and configured, the DARE Test (for storage systems that support the test) is available after an initial health check is run.
- Compression And Dedup Test—Verifies that the most-recent data deduplication test reported no errors.
NOTE: The Compression and Dedup Test (for storage systems that support the test) is available after an initial health check is run.
