Upgrade 10.9.5 to 10.10.5 with Stornext MDC

I am upgrading my 10.9.5 clients to 10.10.5 clients. We have Stornext MDCs. Does anyone have an upgrade guide since there were major changes to how XSAN 4 works?

XSAN Not Mounting: Missing LUNs

Promise E class and J class SAS expansion chassis
ActiveRaid with SAS expansion chassis
QLogic 5800 and 5600 FC switches
Mac 12 core 10.6.8 FinalCutServer Host
StorNext 4.7.1 HA MDC
XSan Clients

StorNext and Suse Linux can not see 2 stripe groups that are associated with the Promise Raid.
Running fs_scsi -p shows all devices except for the missing SG’s from the Promise Raid
Running “paths” in CVadmin shows the same results
The GUI for Active and Promise show all drives, LUNs mounted, controllers up.
Disk Utility shows missing LUNs on the ActiveRaid, but all LUNs for the Promise.

Quantum engineering spent hours on this issue and conclude that it is a hardware issue and can not be repaired in software.
Question: Can the 2 missing stripe groups be restored ?

Xsan4 with StorNext Windows Client Configuration Help!

I wish there was training available or at least more online documentation than what I have found for Xsan4, but there was not and so I wanted to share with you all my story and knowledge. I only had experience with Xsan2 and Xsan4 is completely different. They simplified configuration and do not provide a granular configuration in the GUI, as they did in Xsan2.

It had taken me over 3 weeks to troubleshoot and resolve my issue. Only because I have found that some of the new hardware that we had purchased were at fault. We always assume that new hardware is in good working order straight out of the box.

My advice to you ... always keep in mind that EVERY component that you have in your implementation can be FAULTY/BAD! Never overlook any possibility!!

Because I have ran into issues immediately during my initial setup, I immediately blamed Xsan version 4, but guess what!? ... I'm now using it and it's doing everything I need it to do!!
