Having issues with Long HBA rescan times. Any point in the right direction is appreciated. We already have a high priority ticket in but this coummunity has been helpful more than once! Vsphere 7.0.3.00600, Cisco UCS, Cisco MDS 9132 switches, Pure X90R3 Arrays.

You will have to tell us a bit more, otherwise we are just guessing

VMFS datastores, no RDM's . So far the vendors are pointing fingers at UCS Fnic drivers.

Which UCS servers are you guys using, and on which fw version are they
