Assigning Controller while creating LUN

Je Thomas — Tue, 29 Jun 2010 19:34:50 GMT

Hi all,

Is there a way we can assign a LUN to be owned by a particular controller while creating the LUN in EVA.

Suppose i want to create 2 LUNs i want one LUN to be owned by Controller A and the second by Controller B

Hello,
of course - it is done in Command View when you are presenting vdisk to servers.
so:
1. create vdisk according your need
2. add host (if not done already)
3. present vdisks to host and choose ownership of vdisk during presentation process.

Hello Thomas,

The preferred path/mode setting for each LUN will define which controller would manage the LUN. The default is "no preference" which will make the EVA decide on ownership of LUN.

Yes, you can do it while you create a virtual disk.

Press [Create Vdisk] and enter the data in the "Basic Settings" area as usual.

Then scroll down to "Advanced Settings".

And select from "Preferred path/mode:"

The default is [no preference].
