Checking System Redundancy; Verifying Component Failure; Selecting A Storage System; Checking Redundancy - HP StorageWorks 6100 - Enterprise Virtual Array User Manual

• Hard failure: The disk is no longer functioning properly and has been assigned a failed status.
This type of failure is indicated by an operational state of
The amber fault status indicator on the disk is typically on.
• 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 HP 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, 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
Figure 48.
2. On the Initialized Storage System Properties page, click Check Redundancy. See
3.
If the system is redundant, continue with
If the system is not redundant, information is displayed indicating the cause of the lack of
redundancy. See 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:
