I'm upgrading a SAN. The SAN engineers requested that we gather some iostat output. No problem. Now they are asking for mount points ...again no problem.

However I have found out that mount points do not appear anywhere in my iostat output.
Here is a sample of my output:

dev8-15 0.00 0.00 0.00 0 0
dev10-0 5.00 0.00 0.00 0 0
dev11-0 0.00 0.00 0.00 0 0
dev12-0 3.50 0.00 0.00 0 0
dev13-0 0.00 0.00 0.00 0 0
dev14-0 2.00 0.00 0.00 0 0
dev15-0 2.00 0.00 0.00 0 0
dev16-0 0.00 0.00 0.00 0 0

I used the lines with zeros in hopes it would line up better.
What I'm trying to figure out is how to map my mount points /dev/emppowere3 to the dev entries above.

At first I thought they were major minor number, but they are not.
So, how can I map these drives? Help please.
Thanks.

Run
powermt display dev=all

This will show you the PowerPath pseudo-device (emcpowere for example) and all the /dev/sd* real devices that comprise the multiple paths to the device.

e.g.
Above shows me that my emcpowera is comprised of /dev/sdf, /dev/sdk, /dev/sdp and /dev/sdu.

It also shows me which Clariion it came from as well as which LUN it is on that Clariion. The "PC1 Production RAC" is the storage group I created on the Clariion.
