I have (4) SLES 10 Servers connected to (4) CX-300's via (2) Brocade switches, each server has (2) FC ports. The NaviCLI agent is installed on all servers and all of the storage is working, MPIO is also configured on the servers. Server #4 only sees 1 path to the LUNs on CX-300 #3, however it does see both paths to a LUN on 300 #1, I assume this means the server HBA ports are good. Server #3 sees both paths to CX-300 #3 so I assume this means the CX300 paths are good. All other servers see their LUNs properly.

This seems to eliminate hardware or connectivity but it's just basic troubleshooting so far. Any suggestions on what to try next in tracking down this problem.

Thanks
