Data transfer rate in FC card

Hi
I have hpux 11.11 server having 2 dual port HBA’s [A6826-60001 2Gb Dual Port PCI/PCI-X Fibre Channel Adapter] -- all 4 ports are connected to SAN

How do I identify how much data is transfering through the fc port.

How to identify HBA reaches maximum I/O.

regards
Manoharan

Hi,

You can use fcmsutil /dev/fcd0 or /dev/td0 to find current link speed. If you have mutliple cards you may have to use fcd1,2 ..or td1,2..etc.

To find out how these FC's loaded you may have to use performance measuring tool such as Glance!

If there are no monitoring tools then May have to check the SAN switch ports for c ollecting these metrics and find which port is overloaded..

Re: Data transfer rate in FC card

Simplest way is to measure data read off one of the SAN disks using dd(1).

# time dd if=/dev/vg??/rvol?? of=/dev/null bs=8192 count=1000

dd(1) can also show write throughput as long as you have an expendable lvol (as all data on the selected lvol will be destroyed).

# time dd if=/dev/zero of=/dev/vg??/rvol?? bs=8192 count=1000

If your server is connected to a sanswitch, use the sanswitch portperfshow command to identify the ammount of data transferred through the server's port.
