It is a hardware RAID controller, and there is not an option to omit the hardware RAID data path.

Even if there were, there is still the issue of driver support. There are billions of driver-hours of FreeNAS on the LSI 6Gbps HBA 20.00.07.00 in IT mode and all the bugs are shook out. There's a lesser number of hours on the 12Gbps HBA products but they're known to work with only a caveat or two.

These things do have drivers for FreeBSD, but they're really oriented towards typical "run a program, write a datafile" style usage. #LSI MEGARAID STORAGE MANAGER CENTOS 7 DRIVERS# ZFS can pound continuously on your controller for days doing a scrub or resilver. It really needs to be as close to 100.000000% perfect as possible. The 92xx and 93xx controllers are definitely known to exhibit issues under ZFS-class loads.
You really need the true HBA product and it needs to be in the software-RAID-bludgeoned-out IT mode. If "storcli" runs you have the wrong product. I am sorry that Avago has chosen to mislead people by trying to market this card as a multimode card. It's quite possible that at some point the driver support will actually be up to snuff, but ZFS is *incredibly* demanding. It will pummel your typical RAID controller CPU and cache. It will stress the driver to the breaking point with massive I/O operations. #LSI MEGARAID STORAGE MANAGER CENTOS 7 DRIVERS#.Compatible: IO Device 'MegaRAID SAS GEN2 Controller (PCIID:1000:79:1000:9263)' is compatible for ESX 6.7. Vmhba1 - 0000:01:00.0: IO Device 'MegaRAID SAS GEN2 Controller' from Avago (LSI / Symbios Logic) Compatible: IO Device 'Cougar Point 6 port SATA AHCI Controller (PCIID:8086:1C02:8086:7270)' is compatible for ESX 6.7.0 Vmhba0 - 0000:00:1f.2: IO Device 'Cougar Point 6 port SATA AHCI Controller' from Intel Corporation It complained about my 10G nics possibly not being supported in 6.7 (but they still work), but the storage both reported compatible (the datastore works, but no hardware monitoring). Strangely, I found a Fling for ESXi compatibility checking. Going from 6.5->6.7 just makes me look at the other hypervisor solutions in the future.Įdit: Just found an updated document () showing 6.5 U2 as being latest for LSI provider. Going to v7.0, I'd expect to drop legacy stuff. I really, really hate it when hardware and feature deprecation happens in a point release like this. So now I'll have to reinstall ESXi 6.5 to get around this issue. Unfortunately, when I discovered this and found the instructions to rollback to previous version, both bootbanks say they are 6.7 and cannot be downgraded or reverted. Search your raid card again, and see it probably says 6.7 supported. Search "LSIprovider" on the compatibility check page to see the 6.5 U2. My raid card reports supporting 6.7, so you think all good, right? Nope, not if the LSI provider functionality is no longer supported.
Messed around with different versions of the SMIS and lsi provider files, but ultimately I believe the issue is that the LSI Provider support has ended at 6.5 U2. I just ran into this problem after upgrading from 6.5 to 6.7.
