Critical Event Descriptions

The following reference provides more information about events with a critical priority, shown with this icon in the Event Log.

Critical Event Type and Sense Key/ASC/ASCQ Description
Event 1001 - Channel failed
Sense key/ASC/ASCQ: 6/3F/C3
The controller failed a channel, and will not access drives on this channel any more. The FRU Group Qualifier (byte 26) in the sense data will indicate the 1-relative channel number of the failed channel. This condition is typically caused by a drive ignoring SCSI protocol on one of the controller's destination channels. The controller typically fails a channel if it issued a reset on a channel, and it continued to see drives ignore the SCSI Bus Reset on this channel. Select the Recovery Guru to obtain the recovery procedure.
Event 1010 - Impending drive failure (PFA) detected
Sense key/ASC/ASCQ: 6/5D/80
A drive has reported that a failure prediction threshold has been exceeded. This indicates that the drive may fail within 24 hours. Select the Recovery Guru to obtain the recovery procedure.
Event 1015 - Incorrect mode parameters set on drive
Sense key/ASC/ASCQ: 6/3F/BD
The controller was unable to query the drive for its current critical mode page settings, or was unable to change these to the correct setting. Currently, this indicates the Qerr bit is set incorrectly on the drive specified in the FRU field of the Request Sense data.
Event 202E - Read drive error during interrupted write
Sense key/ASC/ASCQ: 3/11/8A
A media error has occurred on a read operation during interrupted write processing.
Event 2109 - Controller cache not enabled - cache sizes do not match
Sense key/ASC/ASCQ: 6/A1/00
The controller will not allow mirroring to be enabled if the alternate controller's cache size is different. Make sure that both controllers have the same cache size.
Event 210B - Cache between controllers not synchronized
Sense key/ASC/ASCQ: 6/2A/01
The Mode Select parameters changed because of a cache synchronization error during the processing of the most recent Mode Select request. This normally occurs if the controller's alternate pair has not completed its start-of-day routine. If this message persists, contact your Customer Support Representative.
Event 210C - Controller cache battery failed
Sense key/ASC/ASCQ: 6/0C/80
The controller has detected that the battery is (1) not physically present, (2) it is fully discharged, or (3) it has reached its expiration date. Select the Recovery Guru to obtain the recovery procedure.
Event 210E - Controller cache memory recovery failed after power cycle or reset
Sense key/ASC/ASCQ: 6/0C/81
Recovery from a Data Cache error was unsuccessful. User data may have been lost.
Event 2110 - Controller cache memory initialization failed
Sense key/ASC/ASCQ: 6/40/81
The controller has detected the failure of an internal controller component (RAID Buffer). This failure may have been detected during operation as well as during an on-board diagnostic routine.
Event 2113 - Controller cache battery nearing expiration
Sense key/ASC/ASCQ: 6/3F/D9
The cache battery is within the specified number of weeks of failing. Select the Recovery Guru to obtain the recovery procedure.
Event 2229 - Drive failed by controller
Sense key/ASC/ASCQ: None
The controller has failed a drive because of a problem with the drive. Select the Recovery Guru to obtain the recovery procedure.
Event 222D - Drive manually failed
Sense key/ASC/ASCQ: 6/3F/87
The drive was manually failed by a user. Select the Recovery Guru to obtain the recovery procedure.
Event 2247 - Data lost on logical drive during unrecovered interrupted write
Sense key/ASC/ASCQ: 6/3F/EB
An error has occurred during interrupted write processing during the start-of-day routine causing the logical drive to transition to the failed state. Select the Recovery Guru to obtain the recovery procedure.
Event 2248 - Drive failed - write failure
Sense key/ASC/ASCQ: 6/3F/80
The drive failed a write command to it. The drive will be marked failed. Select the Recovery Guru to obtain the recovery procedure.
Event 2249 - Drive capacity less than minimum
Sense key/ASC/ASCQ: 6/3F/8B
The capacity of the drive is not large enough to support all the logical drives that must be reconstructed on it. You should replace the drive with a larger capacity drive.
Event 224A - Drive has wrong block size
Sense key/ASC/ASCQ: 6/3F/8C
The drive's block size does not match that of the other drives in the logical drive. The drive will be marked failed. Select the Recovery Guru to obtain the recovery procedure.
Event 224B - Drive failed - initialization failure
Sense key/ASC/ASCQ: 6/3F/86
The drive failed either a Format Unit command, or a Write operation (issued when a logical drive was initialized). The drive will be marked failed. Select the Recovery Guru to obtain the recovery procedure.
Event 224D - Drive failed - no response at start of day
Sense key/ASC/ASCQ: 6/3F/85
The drive failed a Read Capacity or Read command during the start-of-day routine. The controller was unable to read the configuration information stored on it. Select the Recovery Guru to obtain the recovery procedure.
Event 224E - Drive failed - initialization/reconstruction failure
Sense key/ASC/ASCQ: 6/3F/82
The (previously-failed) drive was marked failed because either (1) the drive failed a Format Unit command issued to it, or (2) the reconstruction on the drive failed due to the controller being unable to restore it (for example, an error occurring on another drive required for reconstruction). Select the Recovery Guru to obtain the recovery procedure.
Event 2250 - Logical Drive failure (3F E0)
Sense key/ASC/ASCQ: 6/3F/E0
The controller has marked the logical drive failed. User data and/or redundancy (parity) can no longer be maintained to ensure availability. The most likely cause is the failure of a single drive in non-redundant configurations or a second drive in a configuration protected by one drive. Select the Recovery Guru to obtain the recovery procedure.
Event 2251 - Drive failed - reconstruction failure
Sense key/ASC/ASCQ: 6/3F/8E
A drive failed due to a reconstruction failure during the start-of-day routine. Select the Recovery Guru to obtain the recovery procedure.
Event 2252 - Drive marked offline during interrupted write
Sense key/ASC/ASCQ: 6/3F/98
An error has occurred during interrupted write processing causing the logical drive to be marked failed. Drives in the array that did not experience the read error will transition to the Offline state and log this error.
Event 2254 - Redundancy (parity) and data mismatch was detected
Sense key/ASC/ASCQ: 6/8E/01
The controller detected inconsistent redundancy (parity)/data during a parity verification.
Event 2255 - Logical Drive definition incompatible with ALT mode - ALT disabled
Sense key/ASC/ASCQ: 6/91/3B
The controller will operate in normal redundant controller mode without performing Auto-LUN transfers.
Event 2602 - Automatic controller firmware synchronization failed
Sense key/ASC/ASCQ: 02/04/81
The versions of firmware on the redundant controllers are not the same because the automatic controller firmware synchronization failed. Controllers with an incompatible version of firmware may cause unexpected results. Try the firmware download again. If the problem persists, contact your Customer Support Representative.
Event 2801 - Storage Subsystem running on UPS battery
Sense key/ASC/ASCQ: 6/3F/C8
The Uninterruptible Power Source (UPS) has indicated that AC power is no longer present and the UPS has switched to standby power. While there is no immediate cause for concern, you should save your data frequently, in case the battery is suddenly depleted.
Event 2803 - UPS battery - two minutes to failure
Sense key/ASC/ASCQ: 6/3F/C9
The Uninterruptible Power Source (UPS) has indicated that its standby power source is nearing depletion. You should take actions to stop I/O activity to the controller. Normally, the controller will change from a write-back caching mode to a write-through mode.
Event 2804 - UPS battery failed
Sense key/ASC/ASCQ: None
The UPS battery has failed.
Event 2807 - Environmental card failed
Sense key/ASC/ASCQ: None
An environmental card has failed. Select the Recovery Guru to obtain the recovery procedure.
Event 2808 - Enclosure ID not unique
Sense key/ASC/ASCQ: 6/98/01
The controller has determined that there are multiple drive enclosures with the same ID selected. Make sure that each drive enclosure has a unique ID setting.
Event 280A - Controller enclosure component missing
Sense key/ASC/ASCQ: 6/3F/C7
A component other than a controller is missing in the controller enclosure (for example, fan, power supply, or battery). The FRU codes indicate the faulty component. Select the Recovery Guru to obtain the recovery procedure.
Event 280B - Controller enclosure component failed
Sense key/ASC/ASCQ: 6/3F/C7

Event 280D - Drive enclosure component failed
Sense key/ASC/ASCQ: 6/3F/C7
A component other than a drive has failed in the drive enclosure (for example, fan, power supply, battery), or an over-temperature condition has occurred. The FRU codes indicate the faulty component. Select the Recovery Guru to obtain the recovery procedure.
Event 280E - Standby power source not fully charged
Sense key/ASC/ASCQ: 6/3F/CA
The Uninterruptible Power Source (UPS) has indicated that its standby power source is not at full capacity.
Event 3019 - Logical Drive ownership changed due to failover
Sense key/ASC/ASCQ: None
The multi-path driver software has changed ownership of the logical drives to the other controller because it could not access the logical drives on the particular path. Select the Recovery Guru to obtain the recovery procedure.
