REPLACING A NEW RAID CONTROLLER.
Hi i have a powervault MD3220 which is currently running on 1 raid controller in slot 1. In slot 0 currently there is no hardware. So i have bought a new controller which i want to put in with a different fireware too.
Can i put it with out powering off the whole unit?

Hello,
I think this is what you are wanting to do. Please let me know if it helps:
The Dell PowerVault Modular Disk (MD) RAID storage arrays support both duplex (dual-controller) and simplex (single-controller) configurations. You can upgrade your existing storage array from a simplex configuration to a duplex configuration without taking the existing storage array offline.

Based on the user guide Charles provided, on page 2, the note did say "To upgrade your existing storage array from a simplex configuration to a duplex configuration without taking the existing storage array offline", hence you can insert the controller without bringing the storage offline.

Whatever it was that you posted didn't come through, could you try sharing it again, and if that fails maybe change the media type?

Hi,
I reviewed and researched the whole thread again. When you add a second controller to the storage array, the redundancy mode will not update automatically. You need to manually configure this setting only when you are upgrading from a single controller to dual controller use. Once you set the redundancy mode, it will stay the same even if you remove or replace a controller.
If the redundancy mode is not correctly set, the additional controller will still be detected, but it won't be usable in case of a failover or to provide a backup path to the storage LUNs.
To check the current redundancy mode for the array, you can look in the Storage Array Profile. You can find this information either through MDSM or in a support bundle at the top.
If the mode is no longer correctly set for the new hardware configuration, you can update the array to Duplex mode by following these steps:
SMcli.exe -n ArrayName -c "set storageArray redundancyMode=duplex;"Hope that helps!

I see and sorry to hear it, then I'm stuck right now too. Frankly, normally I would have expected that to help. Let's see how contribute to our community.

Hello,
Could you please let me know when you have the cable and the output of my process outlined on my earlier post:
