5008 Previously connected drive enclosure enclosure_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.
Drive enclosure enclosure_ID - no drives detected
5010
Explanation: A drive enclosure is detected, but no drives are discovered in the enclosure.
System action: By default, the SAS RAID Module system information indicator is not turned on and the operator is
not notified of this alert by e-mail. Alert clears when drives are discovered in the enclosure or the enclosure is
removed.
Operator response:
v If no drives are present in the enclosure, insert one or more drives.
v If drives are present in the enclosure but are not discovered, reseat the drive enclosure (see "Replacing a Disk
Storage Module (non-concurrent procedure)" on page 161). If the problem persists, perform a Disk Connectivity
Diagnosis.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
5011 Drive enclosure enclosure_ID warning - temperature out of range
Explanation: Elevated temperature has been detected in the drive enclosure.
System action: By default, the SAS RAID Module system information indicator is not turned on and the operator is
not notified of this alert by e-mail. The alert clears automatically when the temperature of the enclosure falls below
the warning level threshold.
Operator response:
1. Make sure the room environment is within specification for the Blade Center. Check the fans used to cool the
controller to see if they are operating correctly.
2. 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).
Drive enclosure enclosure_ID warning - power supply voltage out of range
5012
Explanation: Drive enclosure power supply voltage is not yet critical, but is out of 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 voltage returns to the normal operating range.
Operator response:
1. Replace the drive enclosure power supply.
2. If the problem persists, the voltage sensor in the enclosure might be failing. Replace the drive enclosure (see
"Replacing a Disk Storage Module (non-concurrent procedure)" on page 161).
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
