HP Array Controller HSG V8.7 Software - Manual (Page 379)

CLI Commands B–107
Issue this switch through only one controller. The controller must
contain a valid cache configuration before specifying this switch. See
Chapter 2 for rules regarding valid cache configurations. The
controllers automatically restart when this switch is specified.
Note All unwritten write-cached data is automatically flushed from
cache before restart when the MIRRORED_CACHE switch is
specified. Depending on the amount of data to be flushed, this
command may take several minutes to complete before the controller is
restarted.
The NOMIRRORED_CACHE switch disables mirror mode. Data in
write-back cache is flushed when this switch is entered from mirrored
mode. This switch disables mirrored write-back cache on both
controllers. Therefore, this switch is only to be issued through one
controller. The controller must contain a valid cache configuration
before this switch is assigned. Unlike going from nonmirrored mode to
mirrored mode, going from mirrored mode to nonmirrored mode is
permitted with a failed cache module. The controller automatically
restarts when this switch is specified.
NODE_ID=nnnn-nnnn-nnnn-nnnn checksum
Sets the subsystem worldwide name (node ID). If a situation occurs
that requires you to reset the subsystem worldwide ID (node ID), use
the name and checksum that appear on the sticker on the frame into
which your controller is inserted.
Caution Each subsystem has its own unique worldwide name (node
ID). If you attempt to set the subsystem worldwide name to a name
other than the one that came with the subsystem, the data on the
subsystem will not be accessible. Never set two subsystems to the same
worldwide name; data corruption will occur.
PORT_1_ALPA=
PORT_2_ALPA=
Specifies the hexadecimal arbitrated loop physical address (ALPA) for
the host ports. Use this switch only when LOOP_HARD is specified for
PORT_1_TOPOLOGY or PORT_2_TOPOLOGY. The range of
addresses allowed is 0-EF (hexadecimal). The default value is 69.
