Displaying Fcp Initiator Mode Statistics; Fcp Initiator Mode Statistics - Dell Brocade Adapters Troubleshooting Manual

Displaying fabric statistics through HCM
Use the Fabric Statistics dialog box to monitor a variety of port data.
1. Launch the HCM.
2. Select the FC port from the device tree window.
3. Click Monitor > Statistics > Fabric Statistics.

Displaying FCP initiator mode statistics

Use the fcpim --stats command to display FCP initiator mode statistics and attributes.
fcpim --stats <port_id> <pcifn> <rpwwn> [-l <lpwwn>
where:
stats
pcifn
-l lpwwn
-l rpwwn
To clear FCP initiator mode statistics, enter the following command.
fcpim --statsclr <pcifn> <rpwwn [-l <lpwwn>]

FCP initiator mode statistics

Use HCM to display FCP IM module statistics for each initiator target nexus (ITN). Statistics display
such as I/Os waiting for circular queue space, number of I/O context requests, I/O abort requests,
number of task management I/O context requests, I/O completions with OK status, number of
successful firmware I/O underrun operations, number of successful firmware I/O overrun
operations, aborted I/O requests, I/O timeouts, I/O selection timeouts, I/O protocol errors, host I/O
abort requests, PRLI statistics, and remote port statistics.
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.
Enabling and disabling profiling for FCP initiator mode statistics through BCU
When profiling is enabled, I/O latency data is distributed based on I/O size (average, minimum, and
maximum). You can use this to study typical application I/O patterns, and this may help in tuning
adapters, fabric, and targets for better performance. You must run the fcpim --stats command to
display this data.
