failover a controller on an equallogic array
I want to fail controller 0 to controller 1 on a production equallogic array (during a maintenance window). Is there a way to failover a controller without having to pull power on the controller?
Thanks,

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.

We had an issue with one of our controllers dying and I managed to simulate a failover by restarting as above and it works perfectly , but i have a question , how come when i go on the networks tab , i cant see the management and ISCSI IP addresses like the other 2 arrays that we have

Hello,
Usually this points to an issue getting data from the array to the GUI. As a check you can go to the CLI and see if that's the case.
GroupName>member select MEMBERNAME show eths
That will show you how the network ports are configured.
If the output doesn't show there or is very sluggish I would suggest opening a support case. I have seen this when an array is extremely busy.
I would also consider upgrading the firmware. v7.1.5 was released in April 2015. There have been many improvements since then.
Regards,
Don
Rather than add to an old thread, it's better to start a new one. Especially when your issue isn't the same as the thread.
