Remember that some events are the result of other events; one event can cause a cascade of others if left unfixed. For
example, a problem with a hard drive causes a warning event, “Hard drive error found”, which could lead to a
consistency check error event, “Consistency check on logical drive error”, which could lead to a serious event, “A hard
disk has failed”, which could lead to a critical event, “A logical drive has failed.”
7.11.2 Repair an Array
Events that may cause an array to need repair:
• Expand capacity stopped
• Rebuild stopped
• New device failure
• Device failure
To repair an array, first see 6.2.2 Viewing Event Details on page 111. The event details tell you the event ID and give
you a description of the event that caused the array to need repair. Using this information, take measures to fix the
problem:
• Check, all cable connections, to be sure none is disconnected or broken.
• Check that all logical drives are present and functioning. If needed, see
7.11.3 Repair a Logical Drive on
page 197.
• Replace any parts that need to be replaced, such as a failed fan.
• If expanding an array, make sure that the logical drives and physical drives can support the expansion. See 5.8
Expanding an Array on page 102 for more information.
7.11.3 Repair a Logical Drive
Events that may cause a logical drive to need repair:
• The logical drive is critical
• Logical drive failure
• Logical drive initialization failure
• Disk failure
• Consistency check error or failure
• A drive has been spun down
To repair a logical drive, first see 6.2.2 Viewing Event Details on page 111. The event details tell you the event ID and
give you a description of the event that caused the logical drive to need repair. Using this information, take measures to
fix the problem:
• Check, all cable connections, to be sure none is disconnected or broken.
• Check that all physical drives in the logical drive are present and functioning. Replace physical drives as needed.
• Replace any parts that need to be replaced, such as a failed disk.
• Check that the controller is installed and has power.
• If a consistency check had an error or failed, try again. If this problem persists, replace the disk drive. Check the
errors other generated errors to identify the drive.
