Hello,   Yes, that is correct.  As long as the array RAIDset is not in a rebuilding or initial build state the restart will just failover to the other controller w/o issue.   When you run RSW, it forces you to set the RAID type.  To avoid that, use the serial port instead.  Then if you wanted to up upgrade the new 6210 to the latest before putting it into service you can do so.  Since the 6210 won't come with the latest version of EQL firmware.  Run through the setup process, enable the other interface but don't define the RAID level.  Then you can upload the firmware and update it quickly.  When you set the RAID type you can option to delay making the space available until after the RAIDset builds.  This is helpful if the new member is going to be in the same pool as the others and you want to prevent any performance impact.   Once the build finishes it will start moving data to the new member automatically.   GrpName>mem sel  raid-policy raid6 delay-data-move   Regards,  Don  
I have a PS6210xs and PS6000 in a group and need to upgrade both to the newest firmware before adding a new PS6210x that is at 8.1.x. The 8.1.4 release notes pdf says this (page 11): "Using the Remote Setup Wizard (RSW) or RSWcli Utility With Dell EqualLogic ArraysAfter the initial setup of a new EqualLogic array, when RAID is configured, a RAID verification process occurs. Depending on the type of array, this RAID verification could take days. The new array’s capacity is available for use during this RAID verification process. When you update to array firmware version 8.0 or later, a restart of the array is necessary to complete the update process, but is not permitted until the RAID verification process is completed. You should account for this extra time in your infrastructure’s maintenance window." This doesn't apply to the updates for my existing arrays that I'll update first, correct? In other words, the existing arrays will do the controller rollover just like with the 7.1.x updates so that the LUNs won't go offline, right?
Updating from 7.1.9 to 8.1.4
