Hi folks,
We have a pair of 3240's in an HA pair, and they're each using two single mode VIF's, one each for ISCSI and CIFS.
Each single mode VIF contains, in turn, two static multimode VIF's, each containing two physical interfaces. Each multimode VIF is connected to a separate Cisco 6500 chassis.
We are now upgrading those Cisco 6500 chassis with a couple of Nexus switches using vPC, which allows a single port channel to be configured across both switches. This allows the use of all 4 interfaces in a single multimode VIF. Yay!
What this means, however, is that I must destroy the existing single mode and static multimode CIFS and ISCSI VIF's to create a new dynamic multimode VIF for each, each containing four interfaces. I think I'm probably OK with the mechanics of the VIF destruction and creation process, either from the CLI or OnCommand, but I imagine there are other things I'll need to look at afterwards.
I'll assign the same IP address to each VIF on each filer and configure the switches, but what do I need to worry about on the filers to ensure that HA is still working properly, that my Hyper-V cluster nodes still see the filer as the same ISCSI portal, and that my Windows clients can still see the CIFS shares at the same sharename?
Can anyone give me a hand on a good plan to approach the reconfig? Thanks for the help!
Ian
