HBA throughput monitoring

[Ra Jose]

I have 2 HBAs on my rp7420 running HP-UX 11iv1 with up-to-date patches. They use LVM with powerpath. Are there any HP tools to measure the throughput of HBAs (preferably real time).
I can check the sar -d /iostat to see disk I/O.
But, wondering any such tools to measure how much IO is going thru each HBA.

Thank you all for your replies.

I know you can see it from the switch level. We have HP branded Brocade switches and you can watch the throughput.

It might be easier then trying to see it from the host side.

you can try :
gpm (glance)
It's a graphic performance monitor ..

Use the switch statistics. Glance is a great tool but it looks at the endpoint (ie, LUNs or disks) and not the intermediate HBA. Multiple HBAs (alternate paths) make this type of measurement just about impossible.

Shalom,

Must agree with Bill on this.

fcmsutil

provides precious little data, but its good for snapshots.

I believe, fcmsutil is closest we can get
from server to measure HBA performance.

There may be tools available from EMC. We use connectrix (fiber switch) that has 64 ports. Our server HBAs connect to one of these ports. We have 2 switches. Each HBA connects to one port on each switch. These switches connect to symmetrix (dmx2000).

Thank you all for your responses.

Thank you all.

FYI,

you can also use "powermt display -i 10"

this will give you io and kb /s ..

man powermt or powermt -? for details.

[Ra Jose]

What version of powermt is this? I have powerpath version HP.4.1.0_b155.
I can do powermt display every=10
But I could find -i option.
