RDM LUN ID problem in cluster

[hhmz]

HI!

First of all i must describe how it looks my Vmware vSphere Environment. In one HA/DRS cluster i have five ESX 4.0 U2 and all ESX are connected to EMC san. Than i have one VM which has presented RDM lun. RDM lun is virtual mode. The problem is that i added one ESX later that other and now this ESX has different LUN id and i cannot migrate this VM to this ESX. I know that all RDM LUN must be same, but how can i repair this.

Any idea to fix this?

Regards

you have to keep the same lun the same lun number across all hosts,

redo lun masking on EMC san for other hosts

I agree with binoche. You have to keep the same ID across all hosts.
