Fiber Channel activity

[Stuart Powell]

I have two fiber channel interfaces accessing disk arrays across an arbitrated
loop SAN. I have removed all of the lvm connections to the disk arrays from
one of the fiber channel interfaces and would like to confirm that there is no
data activity on that interface. Is anyone aware of a method to monitor or check the
activity level on that interface?

Stuart,

Have you tried using glance?

Harry,

I looked at the function keys in the ASCII version of glance 2.40 but didn't see anything that would look at an interface other than network.

I'm not familar with the GUI version, but it is loaded.

vgdisplay -v | egrep "VG Name|PV Name" must not show any of disk accesed by that card.

fcutil is an utility for statistics/test fc cards. See man fcutil

fcmsutil stat
displays driver statistics. See man fcmsutil.

Hi Stuart


Please ensure that the physical devices associated with the fibre channel and not the primary links or you can reduce the volume groups if you have done primary secondary . Also the fibre channels are pluggable you can disconnect and connect them back w/o losing connecitivity for a small time interval.

John,

Good call, forgot about that (fcmsutil)!

When I enter man fcmsutil I get:
stdin: not in compressed format
Reformatting entry. Wait... aborted (sorry)

Any ideas?

Hi,

where the interfaces connected to a switch?
For Ex. with a brocade switch you can say showPerfPort something like that. (on the switch)
then you can see waht traffic runs over the port.

Good Luck

Andi,

This interface is on an arbitrate loop connected to an unmanaged hub on the SAN.
Good idea.

Have attached 'man fcmsutil' from an 11.00 server.
