Maintenance Commands
8-176reset fiber-link
8
This command resets the disk device, queries the device for ID, size and other
information, and initiates self-testing by the device. Upon successful completion,
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 duplicated
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, including demand testing, is prevented except 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, scheduled and
periodic testing and other system software access are blocked. In this case, the
host-adapter must first be released before the disk can be released.
When the host-adapter is taken out of service due to test or reset failures, and
becomes uninstalled, the disk is also placed in the uninstalled state and all
access by system software, including resets, is blocked.

CAUTION:
The reset fiber-link command is destructive on standard and high reliability
systems (simplex PNC), and may cause an entire port network to be
removed from service.
This command resets the Expansion Interface and/or Switch Node Interface
circuit packs that are endpoints of a specified fiber link, dropping the link in the
process.
A fiber link must be busied out before being reset. To busyout a fiber on critical
reliability systems, the fiber must be on the standby PNC and the standby PNC
must first be busied out. See
busyout fiber-link
for associated interactions.
The list fiber-link command displays a list of fiber links and their locations.
