ONTAP Upgrade fails with error: Duplicate initiators are mapped to the same LUN
Applies to
- ONTAP 9
- Automated Non-Disruptive Upgrade (ANDU)
- iSCSI
Issue
Upgrade might fail with errors about being unable to normalize initiator names when upgrading ONTAP on a cluster with initiators that contain upper case characters.
After a node reboots on the newer ONTAP version, the ANDU pauses due to the upgrade not completing(for example):
cluster1::> version
NetApp Release 9.9.1P6: Tue Dec 21 13:38:22 UTC 2021
Info: The output from the version command above may not be correct because
upgrade is in progress or has failed in one or more nodes in the cluster.
Use the "upgrade-revert show" command in advanced mode to view the status
of upgrade.
cluster1::*> system node upgrade-revert show
(system node upgrade-revert show)
Node: cluster1-01 Status:
aborted
Status Message: The upgrade aborted. Contact support personnel for the upgrade repair procedure.
