Verifying Component Failure - HP StorageWorks EVA 3000 Replacement Instructions

• Impending failure - although the disk is still functioning, errors have
been detected that indicate an impending failure. This type of
failure is not accompanied by a failed status.
CAUTION:
A disk with an impending failure will appear to be operating
normally in Command View EVA, and the fault light on the disk
will not be on. Therefore, it is important the disk be positively
identified before performing the replacement. Make sure you
work with the HP Solution Center to ensure you identify the correct
disk for replacement.
Checking system redundancy
Before replacing a disk, you should check the redundancy status of
the entire storage system to ensure a disk can be removed without
impacting data availability.
CAUTION:
Do not proceed with the disk replacement until you are certain
the storage system is redundant.
1.
Open HP Command View EVA and click the icon of the storage
system you want to check. See
2. On the Initialized Storage System Properties page, click Check
Redundancy. See Figure
3. If the system is redundant, continue with
failure.
If the system is not redundant, information is displayed indicating
the cause of the lack of redundancy. Refer to online help for help
in interpreting the information displayed. In this situation, work
with your HP call center agent to determine how to proceed.

Verifying component failure

Before replacing a disk, use the following methods to verify the
component failure:

Verifying component
CAUTION:
If Command View EVA does not present a status consistent with
that of the disk status indicators, or if Command View or Instant
Support Enterprise Edition (ISEE) indicates multiple hardware
failures, contact HP support for assistance. The HP support web
site is located at http://www.hp.com/support
Analyze any failure messages you may have received from system
•
monitoring (ISEE). Error messages identify each disk by its rack,
enclosure, bay, and UUID (World Wide Name). Record this
information to assist you in identifying the correct disk before
replacing it.
The following is a sample of the disk identification information:
FRU List:
Storage System Name:
Storage System World Wide ID: 5000-1FE1-0015-42A0
Disk Drive UUID:
Drive Location ---
Enclosure ID:
Bay ID:
Rack Number:
NOTE:
The Disk Drive UUID corresponds to the disk Node World Wide
Name displayed in Command View.
Check the disk status indicators. See
•
occurred, the Fault indicator should be On.
• Check disk status using Command View EVA:
1. In the Navigation pane, select Storage system > Hardware >
Rack > Disk enclosure > Bay. Use the information from the error
message to guide you to the correct disk.
2. In the Content pane, select the Disk Drive tab.
3.
Check the disk Node World Wide Name against the error
message UUID information recorded earlier to ensure you have
selected the correct disk. See
4.
Check the disk operational state. If a hard failure has occurred,
the operational state should be
impending failure indicates Good status and will continue to do
so until the condition of the disk degrades enough to become
a hard failure.
5. Check the following conditions.
CAUTION:
The following conditions must all have the indicated states
before the disk is removed.
• Requested usage - Ungrouped. See
• Actual usage - Ungrouped. See
If all the above conditions are met, continue with
disk needs to be ungrouped, continue with the following step.
NOTE:
If the above conditions are not met after attempting to
ungroup the disk, contact your HP-authorized service
representative for assistance.
