Examples
The following example assigns a name to more easily identify the logical unit:
SFS-7000P(config)# fc srp lu
0103000820000004cf86a01f000000000000000000000000000000000000000000000000000000000000000000

Description
Default: the configured value of srp-global itl for this LU
category(random/sequential).
Allows the system to maintain a preference for a specific
path. If the number of outstanding I/Os becomes excessive, or
the path fails, the gateway uses an alternate path. When
enabled, the gateway uses the current path until the path
condition changes. Note that frequent switching degrades
performance. Enter the fc srp lu command with this keyword
to enable this feature. Otherwise, use the no form of the
command string to disable this feature. If you enable this
policy, you implicitly disable port failover and port
loadbalancing.
Default: the configured value of srp-global itl for this LU
category(random/sequential).
Sets the maximum number of I/O requests that can be sent per
logical unit. The value, an integer, must fall between 1 and
256. Enter the fc srp lu command with this keyword and the
desired io-hi-mark value to set this feature.
Default: the configured value of the srp-global itl for this LU
category(random/sequential).
Number of times the same I/O request may be sent to a logical
unit. Increase the value if heavy traffic runs, or increase the
min-io-timeout value. The value, an integer, must fall
between 1 and 100. Enter the fc srp lu command with this
keyword and the desired max-retry value to set this feature. -
min-io-timeout timeout Default: the configured value of
srp-global itl for this LU category(random/sequential).
Maximum amount of time allowed for I/O traffic to be
accepted by a logical unit. Increase this value (or increase the
max-retry value) if you use a known slow connection. The
value, an integer, must fall between 1 and 1800.
Specifies a target to add to the LU target list. The LU can be
accessed via the target ports configured. You can add at most
eight targets to a LU one at a time. Enter the fc srp lu
command with this keyword and the desired world-wide port
name (WWPN) of the target port value to add the target port
to the list. Use the no form of this command to remove a
target port from the list.
