I have a Windows 2012R2 Hyper-V host server that hosts 2 DPM 2012R2 servers. The backend DPM storage is 2 HP MSA arrays connected via FC to 3 old single port QLogic HBA cards. One MSA is connected to 2 cards and the other to 1. I'd like to replace the old Qlogic cards with 2 new dual port QLogic cards.
I'm unsure what steps I need to take when replacing the cards without losing my backups. Advice please.
