This command resets the disk devic e, queries the device for ID, size and other
information, and initiates self-testing by the device. Upon s uccessful completi on,
all alarms on that disk are cleared and the device is returned to service.
The cabinet is always 1 and need not be entered. On systems with dup licated
SPEs only, carrier a or b must be entered.
Failure of the reset command places the disk in the uninstalled state. All system
access to the disk, inc luding demand testing, is prevented exc ept for demand
resets.
When the host-adapter is busied out, only the demand busyout and test
commands are permitted on the attached disk. Reset, release, sc heduled and
periodic testing and other system software access are b locked. In this case, the
host-adapter must first be released before the disk can be releas ed.
When the host-adapter is taken out of servic e due to test or reset failures, and
becomes uninstalled, th e disk is also placed in the uninstalled state and all
access by system software, inc luding resets, is bloc ked.
