Hello, I have an old EMD Astra ES 12 SAN which has been working for the last 2 years no issues. My DC went down last weekend and I had to rebuild it. I started from scratch Server 2012 R2. There is a Qlogic Fiber card in there which attached directly to the SAN.
The SAN is setup RAID 6 16TB and the Qlogic sees it and it assigned to the card..
I am NOT very experienced with SANS but enough I have always maintained them and able to fix minor issues. I was able to build this in the first place using old parts due to budget constraints.
The SAN is so old and the company is not around and there are no firmware updates, etc. I have the latest drivers for the Qlogic.
At first I had a problem with Disk Management not seeing the drive. I found out this was Mcafee so for now I have uninstalled that (this is what I used in the past but it was installed AFTER the SAN was working).
Now one of 2 things happens.. Either I open Disk management and it freezes at "connecting to virtual disk service" and I can close it and re-open but it does the same thing.. The other thing I get is that It open and sees the 16TB drive and it is online but when I go to assign a drive letter it freezes.
Either way, Disk management does not like this device.
Tried windows updates, Qlogic updates, etc. Nothing seems to help. I have tried shutting down the SAN and them powering on AFTER I am in disk management and it sees it, but then locks up when I click on refresh.
This data is critical and our backup failed 2 weeks ago. I am moving to a new SAN but need the data off it. There is about 10TB data.
ANY ideas? Suggestions?
Event log shows:

Everything was working until I lost the DC. The DC was upgraded to 2012 R2 last year so the SAN was grandfathered in from Server 2003, but I built in a few years back. I dont remember doing anything differently. Same drivers, same SAN, same server, Same OS,
I tried new fiber cable. I tried another Qlogic card. I am using SanSurfer and the QCC GUI. Those detect the SAN and 16TB.
I am stuck. Worked on this a full week. I will get this to another drive ASAP but need to get to the data,
