Displaying IOC statistics through BCU
Use the ioc command to display IOC statistics.
ioc -–stats --query <ioc_id>
where:
stats
Displays IOC statistics.
query
Displays IOC attributes.
ioc_id
ID of the IOC controller for which you want to display attributes.
The ioc --query command displays such attributes as adapter serial number, model number,
PWWN, firmware and BIOS version, vendor identification, IOC type, and interrupt coalescing status.
Displaying IOC statistics through HCM
Use the IOC Statistics dialog box to monitor a variety of port data.
1. Launch HCM.
2. Select the base adapter port from the device tree window.
3. Click Monitor > Statistics > IOC Statistics.
FCP initiator mode statistics
Use HCM and BCU 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,
and host I/O abort requests.
Displaying FCP initiator mode statistics through BCU
Use the fcpim command to display FCP initiator mode statistics and attributes.
fcpim --stats <port_id> --query <port_id> <rpwwn [-l <lpwwn>]
where:
stats
Displays FCP initiator mode statistics.
query
Displays FCP initiator mode attributes.
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.
lpwwn
Logical PWWN. This is an optional argument. If the -l lpwwn argument is not
specified, the base port is used.
rpwwn
Remote PWWN.
