Issue

After upgrading Data ONTAP, all LUNs attached to the Windows 2008 servers appear offline.

DISKPART> list disk
Disk ### Status Size Free Dyn Gpt
-------- ------ ---- -------------
Disk 0 Online 18 GB 0 B
Disk 1 Offline 306 MB 306 MB *
Disk 2 Offline 306 MB 306 MB *
Disks are good after bringing them back online.

The following configuration applies:

  • Windows Server 2008 or later with SAN Policy set to Offline Shared
  • MPIO of some fashion (ONTAP DSM or MSDSM)
  • Data ONTAP upgrade

Note: Clustered Data ONTAP is not affected because the revision code stays the same for luns mapped to a windows igroup.
