Operating the Control Panel Using Control Panel Menus Mark Log Disk Mark Log Disk. Marks the log disk with information to record the starting time and stopping time of a benchmark test. The log disk is a specially formatted disk that records disk activity (IOs) with the host; it cannot store user data. Copy Firmware Copy Firmware will copy controller firmware from the primary array controller to the secondary array controller. This command will take the disk array offline. Copy Firmware requires that the SCSI bus be quiescent (quieted). Be sure to unmount all LUNs, deactivate any Volume Groups, and make certain that any data based activity that uses LUNs on the disk array has achieved quiescence before using this command. Recover If the disk array is not shutdown properly, it is possible that the data maps in NVRAM memory will be lost. For this reason, the disk array allows the data maps to be periodically written to the disk drives. If the maps are lost, an error code such as "No Address Table" will appear on the display. If your disk array is a boot device, you may have to recover the maps by using the front panel command called "Recover" under the "Cntrl Changes" menu. The Recover command is only supported in controller firmware versions later than HP40, and any patch delivered after IPR9808 release. Disk Changes The Disk Changes menu enables you to change disk parameters for the array. Include Disk Include Disk. Includes a new disk in the array. The array cannot use a newly installed disk until it has been included. Once included, you can use the disk to (1) increase capacity by creating a logical drive using part of or all of the disk capacity, or (2) protect against disk failure by enabling Active Hot Spare if not already enabled. Before a logical drive is created, the disk array can, however have increased performance capability once the new disk has been included. Auto Include NOTE! A disk used by another array will be marked "Previously Used" and will not be automatically included. Use Include Disk to include a "Previously Used" disk. Auto Include should be disabled if you want to run a diagnostic on a new disk before the array begins to use it. Auto Include enables (default) or disables Auto Include when a new disk is installed in the array. 79 Control Panel

Mark Log Disk
Mark Log Disk. Marks the log disk with information to record the starting time and stopping time of a
benchmark test. The log disk is a specially formatted disk that records disk activity (IOs) with the host; it
cannot store user data.
Copy Firmware
Copy Firmware will copy controller firmware from the primary array controller to the secondary array
controller. This command will take the disk array offline. Copy Firmware requires that the SCSI bus be
quiescent (quieted). Be sure to unmount all LUNs, deactivate any Volume Groups, and make certain that
any data based activity that uses LUNs on the disk array has achieved quiescence before using this
command.
Recover
If the disk array is not shutdown properly, it is possible that the data maps in NVRAM memory will be lost.
For this reason, the disk array allows the data maps to be periodically written to the disk drives. If the maps
are lost, an error code such as “No Address Table” will appear on the display. If your disk array is a boot
device, you may have to recover the maps by using the front panel command called “Recover” under the
“Cntrl Changes” menu. The Recover command is only supported in controller firmware versions later than
HP40, and any patch delivered after IPR9808 release.
Disk Changes
The Disk Changes menu enables you to change disk parameters for the array.
Include Disk
Include Disk. Includes a new disk in the array. The array cannot use a newly installed disk until it has been
included. Once included, you can use the disk to (1) increase capacity by creating a logical drive using part
of or all of the disk capacity, or (2) protect against disk failure by enabling Active Hot Spare if not already
enabled. Before a logical drive is created, the disk array can, however have increased performance

Auto Include
NOTE!
A disk used by another array will be marked “Previously Used” and will not be
automatically included. Use Include Disk to include a “Previously Used” disk. Auto Include should
be disabled if you want to run a diagnostic on a new disk before the array begins to use it.
Auto Include enables (default) or disables Auto Include when a new disk is installed in the array.
