Adding a Clustered SR2122 to a SAN

The two SR2122 FC ports on all the clustered SR2122’s are recognized as F-Ports by the FC

switch and as FC HBAs by the Storage Arrays.

After physically connecting the FC port(s), and if zoning is enabled, it is recommended to

create a new zone that includes the FC Port WWPNs and the WWPNs of the storage arrays

that will be serving storage to the SR2122.

Note: Important: Although Multi/Auto Pathing is not supported in a SR2122 clustered

environment,a certain level of failover is available at the SR2122 when configured in a cluster.

Normally, only one SR2122 within the cluster is responsible for the active I/O path between

the iSCSI Initiator and the Storage Array, as an iSCSI Initiator’s I/O cannot be split between

SR2122 Cluster members. If this active Cluster member fails the I/O can switch to another

cluster member. To insure proper failover each cluster member needs one of its FC ports in the

same zone.
