QLogic Fibrechannel fabric setup
Posted on 2011-04-19
I am trying to setup a redundant fabric for our SAN and I am getting strange behavior.
Our servers all have redundant HBAs with multipathing and we are moving up to a second switch.
Both are QLogic Sanbox2-16 with the same firmware v1.3-64-0 (latest we can run on our primary switch, so thats what we are running on both)
I thought I understood this, but apparently I am remiss...
I split the redundant connections from each of the servers and the storage array across both switches. Then I cross-connected the switches.
The servers see the storage array but any real I/O throws all kinds of errors.
When I disconnect the link between the switches, things seem Ok... but now all traffic is on one switch only and I can't load balance paths to the disk array.
Is there a way to implement these two switches as a single fabric? Or is it not at all worth it?
Forgot to mention... I reset all my zoning so no zone is set and I did increment the ID of the second switch to 2.
