fc srp lu
To configure a logical unit, enter the
fc srp lu
command in Global Configuration mode. To delete a
logical unit or to set a LU attribute to the factory default value, use the
no
form of this command.

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