Moving drives to a new chassis
We have a RN312 in RAID1 configuration which we use for sharing some folders and also for providing iSCSI drives to a couple of Windows machines. We are thinking of buying another RN312 chassis (with...
All your data including your configuration is on the disks so it will remain when moving the disks to another chassis. If the only problem is hardware failure then this should work fine.
However sometimes users mistake an issue on the disks for hardware failure or have both hardware failure and another issue. If there is an issue on the disks it will remain when moving the disks to another chassis.
You should regularly backup your data e.g. using software on the PC the iSCSI initiator is running on.
Thank you mdgm!!
Is the firmware also in the drives? Just having one exact model RN31200 as replacement would be enough, or will it have to be a specific release or firmware version?

The OS runs from a boot partition on the drives. but it is also in the flash. With OS6, when you migrate disks the boot process compares the flash version with the on-disk version. If there is a mismatch, than it takes whatever if newer. That is, if the flash is newer. the flash version is installed to the disks. If the boot partition is newer, the flash is updated from the boot partition.
There is also code in there to support ARM->x86 and X64->ARM migration, which is pretty cool.
So you don't need to precisely match the model or the firmware in it's flash.
Still, I do suggest installing a temporary scratch disk in the new unit first, and update the firmware first if that is necessary. Then power down and do the disk migration. Perhaps that is overly cautious, but I'd rather not risk a failed firmware update when I'm migrating. Plus it does provide some assurance that the replacement chassis is working properly.
Thank you very much StephenB!
I'll mark the first answer as the solution as it answers my first question, which is the topic of the post.
But both answers have been equally helpful for me,
Best regards!
