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.
