I have a VNXe 3150 connected to vCenter / ESXi hosts (all 5.5) over iSCSI. Max LUN size is 2 TB on the SAN. I have two 2 TB datastores on SAN / vCenter and have 2 TB free on the SAN. Max LUN size on this device is 2 TB. I want to add an extent to one of the datastores using the 2 TB I have free.
The issue is when I create a LUN on the SAN with the free 2 TB, after rescanning the iSCSI adapter on vCenter, the LUN is presented but also shows up as a named datastore. This prevents me from using it as an extent (it doesn't show up as available storage when increasing the datastore).
How can I present the storage from the SAN so it shows up under Storage in vCenter but doesn't get automatically added as a datastore under Datastores in vCenter? I see other iSCSI LUNs under Storage that are not automatically creating datastores.
Thanks for the help.
