You can configure the exchange-based SAN routing policies to perform all the SnapMirror functions over Fibre Channel in a SAN environment. You can enable the out-of-order delivery (OOD) functionality by using the exchange-based SAN routing policies.
About this task
These exchange-based SAN routing policies must be performed on the appropriate vsan (using vsan 10 in the example that follows).
- Enable OOD for all FCVI ports on the storage system by using the following command: fcnic ood on <fcvi ql portnum>
If OOD is enabled on the storage system, the following is the recommended setting for load balancing:
Source Destination ExchangeID
switch(config)# vsan database
switch(config-vsan-db)# vsan 10 loadbalancing src-dst-ox-id
If OOD is enabled on the storage system, you do not need to enable in-order-guarantee.
- To check if in-order-guarantee is enabled, enter the following command: show in-order-guarantee
- To disable in-order-guarantee for a vsan, enter the following command: no in-order-guarantee vsan 10
- Copy the changes to the startup configuration by using the following command: switch# copy running-config startup-config
