Issue

CVO upgrade of a cluster hosting SVM-DR destinations fails with;
 
 Error: SAN or NVMe LIFs are currently down, potentially causing an outage when the cluster is upgraded.

Cause

  • iSCSI data LIFs are present within a dp-destination vserver and are in an admin 'up' and operational 'down' state
  • iSCSI data LIFs do not perform failover to partner nodes
  • Upgrades are Non-Disruptive-Operations (NDO) and will attempt to failover data LIF's to avoid disrupting client access
    • LIFs that do not perform failover but are also in an operational 'down' state can trigger an outage warning response from ONTAP​​​​​​

Solution

  • Copy the iSCSI data LIF's configuration
    • ::> network interface show -lif <>
  • Modify the the iSCSI data LIFs from the dp-destination vserver to a fully downed state
    • set d 
    • ::*> vserver config override -c "net int modify -vserver <> -lif <> -status-admin down"
  • Delete the iSCSI data LIF
    • ::*> vserver config override -c "net int delete -vserver <> -lif <>"
    • :  : * > cluster image resume-update

  • OPTIONAL: Recreate the iSCSI data LIFs after the upgrade with all relevant parameters

 

Alternate Solution:

Enable the LIF causing the issue

::*> network interface modify -vserver <> -lif <> -status-admin up

Optional: Once the upgrade has completed disable the LIF

::*> network interface modify -vserver <> -lif <> -status-admin down
