LU identifier in 64-byte, hexadecimal format without colons (see
example).
Assigns a textual description to the LU.
Alphanumeric description to assign to the LU.
Configures the device category of the LU: random (disk) or sequential
(tape).
Identifies a LU for a random device.
Identifies a LU for a sequential device
Enables dynamic gateway port failover so that if one gateway port fails,
the other port on the gateway maintains the traffic to the LU.
(Optional) Sets an attribute to its global default value.
Enables gateway port load balancing across multiple ports for this LU to
optimize performance and utilize all available bandwidth.
Enables dynamic path affinity for this LU, which locks a storage
connection to a path for the duration of data transfer to provide faster,
more efficient data delivery.
Configures the maximum amount of I/O that the LU can send to the
initiator.
Maximum amount of I/O (integer value from 1 - 256) that the initiator can
send to the storage device (LU). This value defaults to 5.
Maximum number of times that the initiator unsuccessfully sends data to
a LU before the initiator identifies the LU as inaccessible.
Integer value from 1 - 100. The retry variable defaults to 5.
Configures the maximum amount of time during which the storage device
can accept I/O.
Maximum amount of time during which a storage device can accept I/O.
Integer value from 1 - 1800. This value defaults to 10.
Specifies a target to add to the LU target list.
World-wide port name (WWPN) of the target port to add to the LU target
list.
