r720xd - 3x qle2460 - dell mds3600f - DS4700 - error at disk size

[alexkgr]

Hello everyone,
Really love truenas and the whole ecosystem.
New here and i want your help.
I have a r720xd with 2x e5-2680v2 and 128gb of ram, 26 hdds 1,2 tb and i am trying to connect 2 old storages i own.
One dell mds3600f and one IBM DS4700.
I am using 3 FC cards qle2460.
The problem is that truenas can see the disks but the size is incorrect.

Sizes should be 4.4tb 1.3tb and 1.7tb but it shows MiB

I was using the same cards and the same connection with xcp-ng and everything was working perfectly.
I want to mount these storages to truenas.

Thank you in advance

Fiber channel is not supported. Additionally, trying to run a ZFS pool over fiber channel is likely to result in crushing I/O towards the FC arrays, especially during scrubs or rebuilds. This may cause your system to go totally catatonic for periods.

The 2460 looks to be a 4Gbps card, or about 500MBytes/sec. Each shelf has 16 drives, so each drive is only capable of hitting 33MBytes/sec, which is untenable under ZFS.

So even if there's a resolution for the problem you're seeing, this isn't likely to end well.
