Isolating Port Issues Using Device Manager
To isolate port issues using Device Manager, follow these steps:
Step 1 Choose Interfaces > FC ALL and verify that the Status Oper field is up to determine if the host HBA
and the storage port can provide link level connectivity to their respective switches.
See Table 8-1 on page 8-3 for details on nonoperational interface reasons.
Step 2 If the port is down and offline, set Admin Status to up and click Apply to bring the port online.
Step 3 Repeat Step 1 to determine if the port is online.
If either of the ports fails to remain in the online state, then you may have a faulty GBIC, cabling or
HBA/subsystem port.
