Displaying FCP IM module statistics through BCU
Use the fcpim command to display FCP initiator mode (FCP IM) module statistics.
bcu fcpim --modstats <port_id>
where:
modstats
Displays FCP IM module statistics.
port_id
ID of the port for which you want to display statistics. This could be the
PWWN, port hardware path, or user-specified port name. This could also be
the adapter-index/port-index. For example, to specify adapter 1, port 1, you
would use 1/1 as the port identification.
Displaying FCP IM mode statistics through HCM
Use the following steps to display the FCP IM Statistics dialog box:
1. Launch the HCM.
2. Select the base adapter port from the device tree window.
3. Click Monitor > Statistics > FCP IM Module Statistics.
or
Right-click a port from the device tree and select Statistics > FCP IM Module Statistics.
Logical port statistics
Use HCM and BCU to display logical port statistics for the following:
•
Name server (NS) port logins (plogin) 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
•
Retries
•
Timeouts
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.
