Migrate RDM Drives to pass-trough Controller


Recommended Posts

Hi guys


I currently run DSM6.1.x on a Microserver Gen8 on ESXI 6 with 4 drives mapped as RDM.

Now I want to change the drives to a LSI Controller and run pass-trough config into DSM. CPU is a Xeon.

I am really unsure about the migration path to accomplish that.

Just move SATA cable to the LSI controller, configure pass-trough to DSM and everything is fine? Someone there who did the same?

Backups are available, but my aim is to keep migration as safe as possible for the data and -  I am lazy and do not want to spend hours of rebuild my datastore from the backups. :-)

That is what I would attempt.  Be prepared for suboptimal SATA controller mappings.

Can you grab a few small drives and build up a parallel test environment to try it?


In any case, don't try to repair anything that doesn't come up clean and you can always go back.
