HP Insight Management Agents - Manual (Page 78)

the system is first powered up, the board performs a data compare test between the
mirrored copies. If the data does not match, an error has occurred. Data may have been
lost. Your board may need servicing.
◦ Read Failure - Write cache operations have been permanently disabled. The Array
Accelerator board stores duplicate copies of all data. While reading the data from the
board, memory parity errors have occurred so both copies were corrupted and cannot
be retrieved. Data has been lost. Have the board serviced.
◦ Write Failure - Write cache operations have been permanently disabled. This error occurs
when an unsuccessful attempt was made to write data to the Array Accelerator board.
Data could not be written to write cache memory in duplicate due to the detection of
parity errors. This error does not indicate data loss. Have the Array Accelerator board
serviced.
◦ Config Command - Write cache operations have been permanently disabled. The
configuration of the logical drives has changed. Reconfigure the Array Accelerator board.
◦ Expand in Progress Cache operations are temporarily disabled due to an expand of a
logical drive. When the expand operation completes, the accelerator will be enabled.
◦ Snapshot in Progress - Cache operations are temporarily disabled due to a snapshot
operation that is queued up or in progress. When the snapshot operation completes, the
accelerator will be enabled.
◦ Redundant Low Battery - Cache operations are temporarily disabled. The redundant
controller has insufficient cache battery power.
◦ Redundant Size Mismatch - Cache operations are temporarily disabled. The cache sizes
on the redundant controllers do not match.
◦ Redundant Cache Failure - Cache operations are temporarily disabled. The cache on the
redundant controller has failed.
◦ Excessive ECC Errors - Cache operations have been permanently disabled. The number
of cache lines experiencing excessive ECC errors has reached a preset limit.
◦ POST ECC Errors - Indicates that write cache operations have been permanently disabled.
The cache has been disabled due to a large number of ECC errors detected while testing
the cache during the Power On Self Test (POST).
◦ Unknown - The Storage Agents do not recognize the error code. You may need to update
your software.
Identify Drives
Select the length of time to identify the physical drives that are connected to this controller from
the drop-down list box and then select the Start button. The page will automatically refresh and
display an image of an identified drive and a Stop button. Select the Stop button to end identification
before the time expires.
After the drive identification completes, the page will have to be manually refreshed to display the
Start button. There may be a delay, depending on the length of the HP Management Agents data
collection interval, after the drive identification completes and before the Start button can be
displayed.
Only drives in hot plug trays are supported since the LEDs are part of the tray. If an individual
logical drive or physical drive on this controller is selected while the drives connected to this
controller are currently identified then the other drives will stop identification and only the selected
drive will be identified.
