Autopath - EVA8k controller port
Hi all,
I have a server connected to EVA8K and using autopath. Is there a way for me to identify the controller port for each device path (for the same LUN)?

Re: Autopath - EVA8k controller port
Hi,
look for those 4 devices (c9t6d5) in the output of ioscan -fnkC disk
In the Hardware Path for that device it will have the SAN switch domain ID and port number of the target port (EVA controller). Then you can easily figure out which EVA port is connected to that SAN port.

Stephen

Re: Autopath - EVA8k controller port
These 4 devices are coming from 2 HBA controllers (each controller presents 2 devices for the same LUN because it has 2 paths to each EVA controller).
Grab the #ioscan -kfn output and look for the hardware path for c9t6d5/c11t6d5/c15t6d5/c19t6d5 devices and the hardware path for FC-HBAs (usually /dev/td0 or /dev/fc0) and it will tell you which devices are part of which FC-HBA.

Re: Autopath - EVA8k controller port
Hi Stephen and Amardeep,
thanks, from the ioscan I was able to determine the hardware path and the hba card for each device.
Another example:

With this information, I should be able to determine which SAN switches each device path come from. But from each switch, there are 2 paths to controllers A and B. How can I tell which controller ports for a given device path?
(Planning to free up a controller port, so need to remove the associated device path before that)
