Technology:
Virtualization
Reported In Release:
FOS7.0.0_pha
Technology Area:
Access Gateway
Closed In Release(s):
FOS7.2.1a(Fixed)
Symptom:
A host connected to a NPIV port on an Access Gateway has multiple virtual clients. Only the
physical HBA is able to login. The virtual client logins are rejected.
Condition:
The issue occurs under the following conditions:
1. F-ports have never bounced since upgrading to a FOS version with the Persistent ALPA feature.
2. The Persistent ALPA feature is enabled for the first time.
3. Virtual clients login without first bouncing the Access Gateway port where the host is connected.
Workaround:
Disable all F-ports on the Access Gateway before trying to login virtual clients.
Recovery:
Disable _all_ the affected F-ports, then enable all the affected ports. To determine which ports are
affected, run this command on all F-ports:
ag --printalpamap <F-port_number>
If the CLI comes back with _Hash Table is empty_, then the port is affected.
