fc srp-global itl
dynamic-path-affinity SRP global defaults for LUs of random/sequential access
devices.
Default for random devices: false
Default for sequential devices: false
This value is applied to LU entries as their default setting
at entry creation time. You can overwrite the value on LU
basis later.
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 Frequent switching degrades performance.
Enter the fc srp-global itl command with this keyword to

If you enable this policy, you implicitly disable port
failover and port loadbalancing.
io-hi-mark mark SRP global defaults for LUs of random/sequential access
devices.
Default for random devices: 16
Default for sequential devices: 1
This value is applied to LU entries as their default setting
at entry creation time. You can overwrite the value on LU
basis later.
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. The hi mark defaults to 16. Enter the
fc srp-global itl command with this keyword and the
desired io-hi-mark value to set this feature.
