3 Statistics 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.

Statistics

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.
