  • ONTAP

Issue

  • Newly created LUN not visible by the Hosts although added to correct igroup and paths exist
  • Many LUN may have missing paths and non symmetric paths for example a storage adapter vmhba see different number of paths to same LUN via each HBA port
  • Cisco Autozone feature is used on MDS switches with ESxi 6.7 and nfnic 4.0.0.87 / Qlogic qlnativefc 4.1.14.0
  • ESXi takes a very long time on rebooting during Datastore discovery
Example:
igroup show -v -igroup test_1
Initiators:
51:1:1:2:3 (not logged in)
51:1:1:2:3 (not logged in)
 
LIFs and Ports in good state and up:
net int show -data-protocol fcp
Admin status up
Operational status up
fcp adapter show -node xyz -adapter 2x -instance
fcp adapter show -node xyz -adapter 2y -instance
