1002 Drive enclosureenclosure_ID failure - Redundant SES device is non-functional
Explanation: Two controllers are operating redundantly and the SES device in the drive enclosure is discoverable and functioning for one controller, but not for the other. The controller that cannot communicate with the SES device generates alert 1002. This condition could result from a number of potential root causes.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is notified of this alert by e-mail.
Operator response:
v If a drive enclosure firmware upgrade is in progress, ignore the alert until the firmware upgrade is successfully completed.
v If no drive enclosure firmware upgrade is in progress (including the case where a previous firmware upgrade was unsuccessful), retry the operation using the nonconcurrent drive enclosure firmware upgrade procedure.
v If the firmware upgrade procedure is successful, but alert 1002 persists, perform an Asymmetrical Disk
Connectivity Diagnosis. You may have to replace the controller reporting the alert or replace the drive enclosure (see “Replacing a Disk Storage Module (non-concurrent procedure)” on page 224)..
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
4010 No viable drive groups available in system
Explanation: At least one configured drive group member drive is discovered, but no viable drive groups exist in the system. Non-viable drive groups cannot expose LUNs to any host because the controller cannot create a complete data set from the drives that are present.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is not notified of this alert by e-mail. Alert clears when at least one viable drive group is discovered or created, or when no drive group member drives are present.
Operator response: Perform the following steps:
1. Insert any missing drives.
2. If the drives appear to be inserted but are not discovered by the system, perform a Disk Connectivity Diagnosis.
3. If the controller correctly reports the number of drives, but the missing drives are unavailable, you can either remove the drives that represent the non-viable drive groups or assimilate those drives so that they can be reused to create new spares or new drive groups.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
5008 Previously connected drive enclosureenclosure_ID not found during startup
Explanation: A drive enclosure containing one or more previously configured drives is not discovered in the system.
System action: By default, the SAS RAID Module system information indicator is not turned on and the operator is notified of this alert by e-mail. Alert clears automatically after 120 seconds.
Operator response: Acknowledge to clear the alert immediately. If the missing drive enclosure is an expected condition, ignore the alert. If the reported enclosure is not missing, perform a Disk Connectivity Diagnosis.

Operator response:
1. Replace the drive enclosure power supply.
2. If the problem persists, the current sensor in the enclosure might be failing. Replace the drive enclosure (see
“Replacing a Disk Storage Module (non-concurrent procedure)” on page 224).
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
5014 Drive enclosureenclosure_ID firmware mismatch exists. Reboot system or execute controller firmware update.
Explanation: The controller queries the firmware revision level of each drive enclosure in the system. During system boot up or as part of controller firmware upgrade, the controller automatically updates all connected drive
enclosures. However, connecting a drive enclosure to a system that is already operational does not trigger a firmware update. If the drive enclosure firmware revision does not match the current controller firmware level, alert 5014 is generated.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is not notified of this alert by e-mail. Alert clears when the firmware in the drive enclosure is updated.
Operator response: You can correct the firmware mismatch by performing either of the following tasks:
v If the firmware revision of the drive enclosure is compatible with the procedure, perform a concurrent controller firmware update..
v Reboot the system. The controller automatically updates the drive enclosure firmware as part of the boot-up procedure.
5011 • 5014
Note: The drive enclosure firmware update process can take minutes to complete. During that time, the system will be offline and unavailable.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
9004 Drive enclosureenclosure_ID firmware update failed
Explanation: A drive enclosure firmware update has failed. The firmware update happens either automatically at system boot-up (because the firmware revision level of the drive enclosure does not match the current controller firmware level) or as part of a controller firmware update procedure.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is not notified of this alert by e-mail. Alert clears when the enclosure is removed or another firmware update is initiated.
Operator response:
1. Acknowledge to clear the alert immediately.
2. Try again to update the drive enclosure firmware.
3. If this update is unsuccessful, perform a non-concurrent controller firmware update.
4. If the problem persists, perform a Disk Connectivity Diagnosis.
5. If no other solution has worked, replace the drive enclosure (see “Replacing a Disk Storage Module (non-concurrent procedure)” on page 224).
9005 Drive enclosureenclosure_ID fault condition - temperature out of range
Explanation: The temperature detected in the enclosure is outside the normal operating range.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is notified of this alert by e-mail. The alert clears automatically when the enclosure temperature returns to the normal operating range.
Operator response:
1. Make sure the room environment is within specification for the Blade Center.
2. Check the fans used to cool the enclosure to see if they are operating correctly.
3. If no cooling problem exists, the temperature sensor in the enclosure might be malfunctioning. Replace the drive enclosure (see “Replacing a Disk Storage Module (non-concurrent procedure)” on page 224).
9006 Drive enclosureenclosure_ID fault condition - power supply voltage out of range
Explanation: The voltage detected in the enclosure is outside the normal operating range. Potential causes are power supply failure and voltage sensor failure.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is notified of this alert by e-mail. The alert clears automatically when the enclosure voltage returns to the normal operating range.
Operator response: Replace the drive enclosure power supply. If the problem persists, the voltage sensor in the enclosure might be malfunctioning. Replace the drive enclosure (see “Replacing a Disk Storage Module
(non-concurrent procedure)” on page 224).

9004 • 9007
9008 Drive enclosureenclosure_ID fault condition - critical fan failure
Explanation: The drive enclosure cooling fan is contained in the power supply modules directly behind each drive enclosure. Alert 9008 is generated when no fan directly behind the corresponding drive enclosure is functioning.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is notified of this alert by e-mail. The drive enclosure automatically powers down the drives after a five-minute delay.
The controller performs an orderly system shutdown and then waits for the condition to be cleared before rebooting and restarting the system.
Operator response: Ensure that at least one working power supply is installed behind each drive enclosure. If the fan on an installed power supply is not working, perform a concurrent power supply replacement.
You can choose to run the system without the drive enclosure that is reporting the problem. To do so, perform the following steps:
1. Wait for the shutdown to complete.
2. Remove the drive enclosure.
3. Reboot the system.
Note: If the controller was unable to complete the orderly shutdown before the drive enclosure removed power from the drives, data might be stuck in cache. To avoid indeterminate data loss, ensure that the “data in cache” indicator is not illuminated before removing any controller or battery. Do not restart the system with any previously connected drive missing.
