I have a HP C7000 Blade chassis that have Ethernet switches in Interconnect bays 1-4, 1GB Fiber Passthrus in 5-6 and SAS switches in 7-8.
Currently I have three blade servers that are using the fiber passthrus to connect to two HP FC switches. Each server has one connection through each passthru. I am running MPIO on each server.
I have recently purchased (2) HP Brodcade 8GB interconnect switches to replace the passthrus with. Ultimately the HP FC switches and connected SAN are being replaced with new equipment.
What I want to do it to replace the passthrus without any down time. Is is possible to remove one of the passthrus and replace it with the switch, get it configured so that server would be connected to the SAN through two switches (HP FC and Brodcade), then replace the other passthru with the other Brodcade switch?
If anyone has done this, do you have a procedure?
