Compaq HSZ80 manual 131, MAXIMUMCACHEDTRANSFER=n MAXIMUMCACHEDTRANSFER=32 Default

5–131

PARTITION=partition_number

Identifies the unit number for a partition on a container. The partition-numberidentifies the partition associated with the unit number being added. Use the SHOW container-namecommand to find the partition numbers used by a storageset or a single-disk unit.

NOTE: Do not split partitioned units across ports. Partitioned units must be on a single port.

MAXIMUM_CACHED_TRANSFER=n

MAXIMUM_CACHED_TRANSFER=32 (Default)

The controller does not cache any transfers over the set size. Accepted values are 1 through 2048.

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 host’s 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_ID (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.
