MDS 9506 ISLs
Hello,
I have mds1 and mds2 at a location called Pas. I also have mds1 and mds2 and a location called Alton about 1 mile away. We recently turned on fiber between the two sites. Pas-mds1 has an ISL to Alton-mds1 (vsan101). Pas-mds2 has an ISL to Alton-mds2 (vasn201). Each ISL is made up of 2 ports running at 2Gbs. I have an AIX host in Alton that has 2 HBAs and is connected to Alton-mds1 and Alton-mds2. It is zoned to 8b1 and 9b1 ports on DMX4 in Pas. Those 2 dmx ports are on Pas-mds1 and Pas-mds2. We communicates across the ISLs and vsan101 and 201. As I am copying data on the AIX host across the ISLs it is extremely slow. Copying 10 GB of data is taking 2 hours.
Fabric Manager has a menu item for "Performance". If I select performance I can then select "ISLs in Real Time" and monitor the Tx and Rx stats on the ISLs. Even when I am doing large copy jobs the screen shows very low numbers with less than 1% utilization. Is there some other tool (maybe command line) that I can use to monitor the traffic going accross these ISLs?

Have you also checked the performance on the ports between the host and the switch and the target and the switch? How have you decided the issue is over the ISL connection and not the host / target ports?
Thank you.
