we have got two VNX5300 (BLOCK ONLY) systems. One is named "VNX1" and the other one "VNX2".
Both are integrated in vcenter 5 with the latest VSI plugin.
It looks like that vCenter does swap the names of the two systems. The system "VNX1" ist displayed as "VNX2" and vice versa.
DNS and reverse DNS are working. Name resolution displays the right names. I can ping both SPs per system. When looking at one of the vnx systems via web gui they look like they shoud.
