CVO upgrade fails due to SAN or NVME LIFS being down
Applies to
- ONTAP 9
- CVO
- SVM-DR
- iSCSI/SAN
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
set d::*> vserver config override -c "net int create -vserver <> -lif <>"- network interface create
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
