Measures reported by RaidctlTest

Solaris servers (particularly, Solaris v10 and above) come with a default RAID controller. If required, the Solaris administrator can set up additional hardware RAID volumes on LSI host bus adapters (HBAs) on the server. To ensure continuous availability and integrity of the data stored in the RAID volumes, administrators should keep an eye on the overall health and operational state of each RAID volume in use on the Solaris server. This is where the RaidctlTest helps.

This test reports the current state of each RAID volume on the Solaris server, and thus brings to light those volumes that have failed, missing, or in a degraded state. By pointing administrators to real/probable abnormalities in the RAID volumes, the test prompts administrators to quickly initiate pre-emptive action and prevent the imminent data loss.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Status Indicates the current health state of this RAID volume.   The values that this measure can take and their corresponding numeric values are as follows:

Measure Value Numeric Value
OK 0
Optimal 1
Sync 2
Resyncing 3
Degraded 4
Failed 5
Missing 6

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current state of the RAID volume. In the graph of this measure however, the same is represented using the corresponding numeric equivalents only.
