IOC statistics

Use BCU and HCM to display port-level statistics for the I/O controller through the BCU and HCM.
The I/O controller refers to the firmware entity controlling the port. The following types of IOC
statistics are displayed:
•
•
•
•
•
•
•
66
If the adapter is not showing in the fabric, check the FLOGI sent and FLOGI accept statistics. If
the counts do not match, the switch or fabric may not be ready to respond. This is normal as
long as it does not persist. If the problem persists, this could indicate a problem in the fabric or
a protocol issue between the adapter and fabric.
If fabric offline counts increase and fabric maintenance is not being done, this may indicate a
serious fabric problem. Slow fabric performance or hosts unable to address storage could also
be seen.
ID of the adapter 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.
