CAUTION: A disk with an impending failure will appear to be operating normally in HP Command View EVA, and the fault light on the disk will not be on. Therefore, it is important that you positively identify the disk before performing the replacement. Work with the HP Solution Center to ensure you identify the correct disk for replacement. Checking system redundancy Before replacing a disk, 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 (Figure 1). 2. On the Initialized Storage System Properties window, click Check Redundancy (Figure 2). 3. If the system is redundant, continue with Verifying component failure. If the system is not redundant, information is displayed indicating the cause of the lack of redundancy. See the HP Command View EVA online help to interpret the information that is displayed. In this situation, work with your HP call center agent to determine how to proceed. Figure 1 Selecting a storage system CAUTION: If HP Command View EVA does not present a status consistent with the disk status indicators, or if HP Command View EVA or your system monitoring tool indicates multiple hardware failures, contact HP support for assistance (http://www.hp.com/support). • Analyze any failure messages received. 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: EVA_1 Storage System World Wide ID: 5000-1FE1-0015-42A0 Disk Drive UUID: 2000-0000-871D-FE60 Drive Location --- Enclosure ID: 8 Bay ID: 1 Rack Number: 0 NOTE: The Disk Drive UUID corresponds to the disk Node World Wide Name displayed in HP Command View EVA. • Check the disk status indicators (Figure 3). If a hard failure has occurred, the fault indicator should be On. • Check the disk status using HP 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 (Figure 4). 4. Check the disk operational state. If a hard failure has occurred, the operational state should be Failed. A disk with an impending failure indicates Good status until the condition of the disk degrades enough to become a hard failure. 5. Verify that the Requested usage and Actual usage fields display Ungrouped (Figure 6). CAUTION: Both fields must display Ungrouped before you remove the disk. Figure 2 Checking redundancy Verifying component failure Before replacing a disk, use the following methods to verify component failure: If fields display Ungrouped, continue with Step 7. If you must ungroup the disk, continue with the following step. NOTE: If the fields do not display Ungrouped after you attempt to ungroup the disk, contact your HP-authorized service representative for assistance. 6. For an impending failure, you must ungroup the disk before you remove it: Page 2

CAUTION:
A disk with an impending failure will appear to be operating
normally in HP Command View EVA, and the fault light on the
disk will not be on. Therefore, it is important that you positively
identify the disk before performing the replacement. Work with
the HP Solution Center to ensure you identify the correct disk for
replacement.
Checking system redundancy
Before replacing a disk, 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 (
Figure 1
).
2.
On the Initialized Storage System Properties window, click
Check
Redundancy
(
Figure 2
).
3.
If the system is redundant, continue with
Verifying component
failure
.
If the system is not redundant, information is displayed indicating
the cause of the lack of redundancy. See the HP Command View
EVA online help to interpret the information that is 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 component
failure:
CAUTION:
If HP Command View EVA does not present a status consistent
with the disk status indicators, or if HP Command View EVA or
your system monitoring tool indicates multiple hardware failures,
contact HP support for assistance (

Analyze any failure messages received. 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 identi
fi
cation information:
FRU List:
Storage System Name:
EVA_1
Storage System World Wide ID: 5000-1FE1-0015-42A0
Disk Drive UUID:
2000-0000-871D-FE60
Drive Location ---
Enclosure ID:
8
Bay ID:
1
Rack Number:
0
NOTE:
The Disk Drive UUID corresponds to the disk Node World Wide
Name displayed in HP Command View EVA.
•
Check the disk status indicators (
Figure 3
). If a hard failure has
occurred, the fault indicator should be On.
•
Check the disk status using HP 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 (
Figure 4
).
4.
Check the disk operational state. If a hard failure has occurred,
the operational state should be
Failed. A disk with an
impending failure indicates Good status until the condition of
the disk degrades enough to become a hard failure.
5.
Verify that the
Requested usage
and
Actual usage
fi
elds display
Ungrouped (
Figure 6
).
CAUTION:
Both
fi
elds must display Ungrouped before you remove the
disk.
If
fi
elds display Ungrouped, continue with
Step 7
. If you must
ungroup the disk, continue with the following step.
NOTE:
If the
fi
elds do not display Ungrouped after you attempt
to ungroup the disk, contact your HP-authorized service
representative for assistance.

For an impending failure, you must ungroup the disk before
you remove it:
