Hi
Running ESXi5 and Vcenter with Isci SAN.
Had a few RDM disks presented via the SAN. The RDM have been storage motion to VMDK.
Then, the Lun have been unpresented on the SAN and I did a 'rescan all HBA' on Host, to remove it from the list, but it has been trying now for our hour and not been able to remove them.
Looking at the vmkernel.log, I can see quite a few loop of similar messages:

The "refCount" message seems to indicate that hopefully it will delete it whan it will be 1, but I am not sure how long it will take before it reaches it.
As far as I know, it might not?
Not sure what to do!
Before we were running ESX4.0 with Fibre SAN and I never had this issue.
Is there something I can do to
1] complete the current removal
2] ensure than it will work faster next time?
Thanks
