failover a controller on an equallogic array

Starting with Firmware version v4.2.x and above, there is a "restart" option in the GUI (select member> member name> service tag, towards the bottom is a restart link). You can also telnet the actual member (using a IP address from one of it's physical interfaces)> login as grpadmin, and type restart. This will cause a restart of the member, and the control module will failover. Be reminded that this will momentarily, restart the array member (takes about 15-20 seconds), and any servers connected to the Group will need to be properly setup to "ride out" the iSCSI time out first (see the firmware release notes for your servers's suggested iSCSI timeout values).

Thanks for the reply - so the restart does not actually restart the "array" but the controller. Is this the best way to test a failver scenario?

I am wanting to verify my iscsi pathways on the switches, servers, etc.

Yes, This method is a good test of your iscsi pathways, switch ISL's, server MPIO/multipath setup as you listed.

Just remember that when you restart a member, the group sets any volumes with data on the member offline (for 15-20 seconds), and fails over to the secondary controller. The group sets the volumes online when the restart completes. Restarting a member has no effect on member, volume, or group configuration information or volume data stored on the member. So as long as you have the iSCSI disk timeout setup properly the host will ride out the restart.
