[OpenIndiana-discuss] FC LUN to ESXi 5.1 Not Recognized After Migration

[Lucas Van Tol]

How did you recreate the LU's?   
It's been a bit since I was doing anything with LUN's (I can't recall if I tested volume migration/rollback w/vmware); but my personal documentation has a note for recreating volumes using stmfadm instead of sbdadm; specifically : 

stmfadm create-lu -p guid=*LUN GUID* /dev/rdsk/*pathtozvol*

for re-creating an LU; and only use sbdadm for creating new lu's.
