Manage an update

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The cluster image update command is used to initiate a Data ONTAP update. The update is preceded by a validation of the cluster to ensure that any issues that might affect the update are identified. There are two types of updates of a cluster. A rolling update updates Data ONTAP one HA pair at a time. This type of update is performed for clusters with fewer than eight nodes or when the -force-rolling option is specified for clusters with eight or more nodes. A batch update is used for clusters of eight or more nodes, and performs updates of multiple HA pairs at the same time.

There are predefined points in the update when the update can be paused (either by the user or by an error). These pause points occur after validation, after download to the boot device, after takeover has completed, and after giveback has completed.

Parameters

-version <text> - Update Version

Specifies the Data ONTAP version to use to update the cluster.

[-nodes {<nodename>|local}] - Node

Specifies the nodes that are to be updated. This parameter is not supported for updates of MetroCluster configurations and for two-stage upgrades.

[-estimate-only <true>] - Estimate Only

Creates a report of the steps that occur during the update without actually doing them.

[-pause-after {none|all}] - Update Pause

Specifies that the update should pause at each predefined pause points (for example, after validation, after download to the boot device, after takeover, and after giveback) during the update.

[-ignore-validation-warning {true|false}] - Ignore Validation

Specifies that the update should proceed even if the validation reports warnings.

[-skip-confirmation {true|false}] - Skip Confirmation

Specifies that a validation that does not detect any error issues should not ask the user to confirm the update but simply proceed with the update.

[-force-rolling <true>] - Force Rolling Update

This option is used for clusters with eight or more nodes to specify that a rolling update (one HA pair at a time) should be done. This parameter is not supported for two-node MetroCluster.

[-stabilize-minutes <integer>] - Minutes to stabilize

Specifies the number of minutes that the update should wait after a takeover or giveback is completed. This allows time for the clients to recover from the pause in I/O that occurs during takeover and giveback. This parameter is not supported for two-pack MetroCluster.

Examples

The following example shows the update operation:

cluster1::> cluster image update -version 8.3

It can take several minutes to complete validation...
