I'm working on a machine with a LSI SAS3008 SAS controller with IR firmware. There are 8 HDDs connected to this in pass-thru/HBA mode and they are in a ZFS raidz2 pool. The firmware is ancient, something like 7.0 or something like that. I'm considering upgrading the firmware to the latest P16 (just came out a week ago) but in the process, I thought I might as well switch it to IT firmware. The intended use is to keep using ZFS on Linux with those 8 drives.
So, I'm just wondering, since the drives are already in pass-thru mode with IR firmware, if I switch to IT firmware, will I be able to import the ZFS pool after rebooting into IT firmware? There is data in that pool that would prefer to remain intact. of course, have backups too - but rather not go through the lengthy process of re-creating the pool and restoring the data.
