Re: Change WWWLN & UUID from cloned LUN
Hi
I assume it's a EVA disk if so you can change the WWLN with SSSU command
SET VDISK "\Virtual Disks\archive" WORLD_WIDE_LUN_NAME=6000-1fe1-ff00-0000
you can see the command in SSSU reference guide
you can also change the lun ID through Command View

Thanks for you reply.
In first place i tried change the WWLN from Command View EVA. When i make [Saves changes] a popup say: "You have chosen to enter a World Wide LUN Name, instead of accepting the default.

Re: Change WWWLN & UUID from cloned LUN
Hi
You are right the procedure I sent you was to create a new LUN with the same
WWWLN as an old LUN . Also If I think about it the cloned LUN has a different
WWWLN than the original what is your operating system.
