Solution 2001248.1 : FS System: Understanding Drive Enclosure Disk Drive States

Applies to:

Oracle FS1-2 Flash Storage System - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

To help understand the drive status field and facilitate corrective action if needed.

This document is intended to explain the different drive states within any given Drive Enclosure in the FS System.

While in normal operation, disks in Drive Enclosures can have different states of operation. The following information explains the differences.

Each Drive Group and RAID level within the Drive Enclosure can have a status of its own, but is influenced by the disk drive status.

RAID Level Status

Once the enclosure has been selected from the GUI, the following states for each drive can be seen.

Normal or *Not Used – good drive state
Rebuild/Copyback/Restore – fix in progress
Booting – should be temporary
Warning – diagnostic failure, in use, consider replacement
Degraded Connectivity – drive only seen by one controller
Critical/Missing -Critical means that RAID has faulted the drive and will need to be forced online to be used in a restore. Drives will be listed as Missing in a drive group list if not present or part number not available. (i.e. Critical/Booting drives)

The next 3 states are used if the drive is replaced or goes offline and comes back.

Recovered
- Online, NOT in use by drive group, has Failure History
- Used for Restore
- NOT Used for Rebuild or copyback
- Changes to Not Used if failure history cleared
Recovered In Use
- Online, In use by drive group, has Failure History
- Changes to Normal if failure history cleared

NOTE: Rules for clearing drive failure history:

Do not clear history if you think the drive is bad
Do not clear history on a drive if any RAID levels in the drive group are Failed
It is OK to clear failure history on a drive if all RAID levels on the drive group are online and you believe the drive is OK

Foreign
- Must be accepted before use
- Expected after spare drive failure and recovery in an SSD Drive Enclosure

*Note. The NOT_USED state is specific for the dedicated hot spare for an SSD Drive Enclosure.
