Logical port statistics

Use HCM and BCU to display logical port statistics for the following:

Discover address (ADISC)

Name server (NS) port logins (plogin) activity

NS port response activity

NS command activity

Register symbolic port name (RSPN_ID) identifier activity

Register FC4 type identifier (RFT_ID) activity

Register FC4 type identifier (RFT_ID) activity

“Get all port ID requests” for a given FC4 type (NS_GID_FT) activity

Port logout (LOGO)

MS command activity

MS port login activity

Port login (PLOGI)

Process login (PRLI)

Process logout (PRLO)

Retries

Timeouts

Registered state change notifications (RSCN) received

Received ELS command activity

Virtual port performance

Use these statistics to help determine if the adapter is not registering with the name server or
cannot access storage. Following are examples of how these statistics indicate these problems:

If name server port login (NS PLOGI) error rejects and unknown name server port login
response (NS login unknown rsp) errors increase, then the adapter most likely cannot log in to
the name server.

If name server register symbolic port name identifier (NS RSPN_ID) or name server register
symbolic port name identifier response (NS RFT_ID rsp) errors or rejects (NS RFT_ID rejects)
are increasing, the adapter has a problem registering with the name server.

If name server “get all port ID response” NS GID_FT rsp), rejects (NS_GID FT rejects), or
unknown responses (NS_GID FT unknown rsp) are increasing, the adapter has a problem
querying the name server for available storage.
