Recover data from failed controller

I recently “decommissioned” my server since I had finally finished the replacement system. long story short I missed some data in the transfer and upon booting this old system I ran into a critical error with my SAS controller and cannot access the drives at all.

I’ve already written the controller off as a lost cause, but I wanted to know my options for importing the old pool on my new system.

The old system was an IBM x3650 (the og, not an M#) running SCALE 24. It had some kind of addon IT SAS HBA since the onboard Adaptec couldn’t do IT IIRC (boot is on HW raid I know). I can’t remember the details of the card, but lspci reports an LSI 2008 (IIRC). The pool used 2 sizes of hard drives one type SAS the other SATA in an external IBM DAS.

The new system is an ASRock Rack D1541D4U-2T8R fully updated. It’s using the integrated LSI 3008 through a Supermicro expanding backplane.

Can I just plug the DAS into the daisy chain from the expander? Honestly I don’t even really know what else I could do. Would the drives show up as normal drives with partitions and stuff on another system?

Not sure if I can edit here, but I can’t find it so I’m commenting to add that for the months leading up to the retirement the server would occasionally fail to find the drives. It always cleared after a restart so I never dug deeper so I’m not certain if this is the same problem. I have tried rebooting short of unplugging the system again.

Hi and welcome to the forums.

Yes the beauty of ZFS is that your pool is not bound to a specific controller so you should be able to attach your drives to your new system and simply import the pool.
