9005

Drive enclosure

enclosure_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:

Make sure the room environment is within specification for the Blade Center.

Check the fans used to cool the enclosure to see if they are operating correctly.

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 161).

9006

Drive enclosure

enclosure_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 161).

9007

Drive enclosure

enclosure_ID

fault condition - power supply current out of range

Explanation:

The current 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 current returns to the normal
operating range.

Operator response:

Replace the drive enclosure power supply. If the problem persists, the current sensor in the

enclosure might be malfunctioning. Replace the drive enclosure (see “Replacing a Disk Storage Module
(non-concurrent procedure)” on page 161).

9008

Drive enclosure

enclosure_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:

Wait for the shutdown to complete.

Remove the drive enclosure.

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
