Duplicate LUN IDs on Compellent iSCSI with VMware?

Hi,

Got a pair of series 40 controllers running latest 6.1.3 firmware, connected via 10GbE iSCSI to an ESXi 5.0 cluster. Using the vSphere client plugin to create storage, and happened to notice something a little weird...  I have two LUNs, both with an ID of 3! the serial number (naa.6000xxxx) is different which I believe is what vSphere uses to identify a volume, but I am slightly intrigued how the plugin has assigned the same LUN to a volume when it has not been changed - this is the ID it would have given the volume when I created it. Is this potentially a problem?  We have some Equallogic stuff in the same cluster which does a similar thing, but that just tends to present everything as LUN 0.

Help!
