Stop Unit
WARNING: DO NOT use during normal operation!
This command is used by engineering when testing various array configurations and should
not be used in normal operation.
Test Unit Ready
This command issues a Test Unit Ready command to the selected disk.
Disk Cache Menu
WARNING: Changing an individual disk's writeback cache setting may take the drive
offline and cause the array to become critical. To change the writeback
cache setting, use the Writeback Cache option under the Disk Configuration
Menu.
This command allows the user to display which drives have writeback cache enabled. It also
allows the user to turn on and off a particular disk's writeback cache. However, this is NOT
the recommended method for changing the writeback cache setting. The preferred method
is to use the Writeback Cache option under the Disk Configuration menu (refer to section
"Writeback Cache" for further information).
Disk drive writeback cache settings should be decided upon and set before any arrays are
created with the drives. In order to protect data, the controller does not permit disk writeback
cache settings for an individual drive to be changed while a drive is an array member.
