Command Line Interface Reference Guide
The MAXIMUM_CACHED_TRANSFER_SIZE switch affects both read and
writeback cache if it is set on a controller that has read and writeback caching.
The use of this switch has the effect of setting both the
MAX_READ_CACHED_TRANSFER_SIZE and the
MAX_WRITE_CACHED_TRANSFER_SIZE switches.
PARTITION=partition-number
Identifies the partition number for a partition on a container. The
partition-number identifies the partition associated with the unit
number being added. Use the SHOW DISKS or SHOW STORAGESETS
command to find the partition numbers used by a storageset or a single-disk
unit.
Note: Transportable units cannot be partitioned. All partitions on a container must be
addressed through the same controller. If you add a unit for a partition and specify the
preferred path switch, all partitions on that container inherit the same path.
PREFERRED_PATH=OTHER_CONTROLLER
PREFERRED_PATH=THIS_CONTROLLER
NOPREFERRED_PATH (default)
Tells the controller whether or not it is expected to bring a unit online in dual
boot situations.
The controllers only use the PREFERRED_PATH setting if they are in a
dual-redundant configuration. If one controller fails, all the devices are
accessed through the remaining controller, ignoring the PREFERRED_PATH
setting.
You can specify the PREFERRED_PATH switch for a single controller
configuration; however, the switch does not take effect until you add a second
controller and configure the two controllers for dual-redundancy.
Note: If controllers are configured to operate in Transparent Failover mode, do not set
the preferred path with the ADD UNITS or SET unit-number
command—otherwise, an error message is generated. This error message indicates
that the assignment of a preferred controller path at the unit level as valid only if
operating in Multiple-bus Failover mode.
