CLI Commands B139
Warning 1000: Access IDs in addition to the one(s) specified
are still enabled. If you wish to enable ONLY the id(s)
listed, disable all access paths (DISABLE_ACCESS_PATH=ALL),
then enable the ones previously listed.
MAXIMUM_CACHED_TRANSFER=n
MAXIMUM_CACHED_TRANSFER=32 (Default)
Sets the largest number of write blocks to be cached by the controller.
The controller does not cache any transfers over the set size. Accepted
values are 1 through 1024.
The MAXIMUM_CACHED_TRANSFER switch affects both read and
write-back cache when set on a controller that has read and write-back
caching.
IDENTIFIER
NOIDENTIFIER
Identifier is an alternative way (other than worldwide name) for some
operating systems to identify the unit.
PREFERRED_PATH=OTHER_CONTROLLER
PREFERRED_PATH=THIS_CONTROLLER
NOPREFERRED_PATH (Default)
May be set only when dual-redundant controllers are operating in a
multiple bus failover configuration. In a multiple bus failover
configuration, the host determines which controller the units are
accessed through. The hosts unit-to-controller settings always take
precedence over the preferred path assigned to units with this switch.
The target ID numbers assigned with the SET controller
PORT_1_ALPA= (or PORT_2) command determines which target ID
number the controller uses to respond to the host.
Note When the controllers are configured to operate in transparent-
failover mode, if you set the PREFERRED_PATH switch with the
ADD UNIT or SET unit-number command, an error message displays
because you can only assign a preferred controller path at the unit level
only when in multiple bus failover mode.
When no preferred path is assigned, the unit is targeted through the
controller which detects the unit first after the controllers start.
