Lun id's for Raw device mapping

[morciod]

We recently moved from EMC DMX to VNX for our SAN storage. When on the DMX the lun-id represented in hex, converted to decimal in VMware. this does not appear to  hold true for the VNX.

Vmware creates the lun-id based on the next available. thus far not a problem because each host sees all luns.

We are creating RDM's... 1 host will see these devices.  what is the best practice for the lun-id configuration

Hello.

Note: This discussion was moved from the VMware ESX 4 community to the VMware vSphere Storage community.

Good Luck!

Vmware creates the lun-id based on the next available.

Are you absolutely sure you did not miss anything in the VNX's configuration. It's hard to believe the LUN ID's are not the ones used for presenting the LUN on the storage system!? I will be setting up VMX within the next few weeks and sure take a close look at this.

no they do not match up....  this is how they configure (thus we manage in a spreadsheet)
