It supports virtual disk migration between those controllers. You should be able to move the drives and it should work. It would be recommended to do a backup just in case there is an issue.
@Suliasi Waqa, Both will work. Ypu can either move all drives to another similar controller or you can move the controller and drives to the new server.
When you only move drives those drives will be shown as Foreign drives on new controller and you need to import the foreign configuration to get the virtual disk available to use on new controller. Which controller you currently have the virtual disk and to which controller are you trying to move the drives? It is also recommended to update BIOS and PERC FW of destination server before trying this
When you move controller and drives virtual disk should be available on new server without any further configuration. You need to ensure controller is supported on the new server as well.
hello everyone, i have a similar problem. The motherboard fails. I have an R730 and I want to switch the disks to an R740. I would like to know if importing with foreign configuration will cause data loss?
Hello everyone, luckily (and thanks to technology) everything has gone well. My old PERC controller I think was an H730 and the new one is a PERC H740P. The configuration of the 8 disks was RAID6. Consulting with my technical partner, he told me that in addition to the controller, the disks save the configuration of the virtual array. Apparently those two PERCs are well compatible. By entering the disks in the same order that they were previously in the bays (important!) The virtual disk was assembled by itself and keeping all the data in its entirety. I didn't have to import foreign disk settings, it did everything by itself. Thanks!
I have a similar issue but slightly different configuration. I have an older R710 with a H700 controller running a RAID 10 virtual disk. I would like to move the disks to a R530 that has a H730 MINI controller. Can I move the raid disks to the new system and simply import the foreign configuration? Assuming that works then I planned on updating the OS from 2016 to 2019. Any pitfalls there?
Side note - would also like to better understand how/where RAID configurations are stored and how the controller detects them as foreign. Any suggested articles?
I don't believe that what you're wanting to do will work. I haven't tried myself, as it isn't a supported operation, so it may work. That said, the controllers are 2 generations apart, so I would hesitate to get expectations too high (H700 -> H710 -> H730).
As for the RAID question, my understanding is that the controller has a record of the arrays it controls, but that RAID metadata is also stored on the drives. This is how a replacement RAID controller is able to import a configuration in a server. There can be a number of reasons that a drive drops into a foreign configuration, such as if it were to stop responding to the controller or if there were some kind of data mismatch. The Dell articles I can find that talk about controllers and foreign configurations are written more with the goal of correcting the issue, though. I haven't seen anything that really expands on how it works.

I have the issues with the Motherboard.
We have to move the Controller with Virtual Disk or only the DISK?

Hello,
it depends of PERC, which controllers are installed?
Thanks
Marco
