Scheduling a Cluster Upgrade

Scheduled cluster upgrade allows you to schedule the upgrade to a specified time to avoid manual intervention. The cluster is upgraded automatically at the scheduled time. You can view, delete, or reschedule the scheduled cluster upgrade.

You can also schedule cluster upgrade for one or more profiles at the same time or different times.

When a Mobility Conductor reboots or a process restarts, this feature has the ability to preserve the configured scheduled upgrades. It also allows you to synchronize the scheduled upgrades to a standby Mobility Conductor. If a Mobility Conductor has active and standby devices configured, then the scheduled upgrade information will be synchronized between active and standby through database synchronization. The upgrade is initiated when the Mobility Conductor becomes active.

Key Considerations

Some of the key considerations are:

• Upgrades can be schedule only to a future time, maximum of 30 days from the managed device's current time.
• The time scheduled is always in reference to the managed devices in a cluster.
• All the network nodes have to be NTP Network Time Protocol. NTP is a protocol for synchronizing the clocks of computers over a network. synchronized.

Limitation

Some of the limitations are:

• DST Daylight Saving Time. DST is also known as summer time that refers to the practice of advancing clocks, so that evenings have more daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn. time change hour is not automatically adjusted for a scheduled upgrade.
• Time changed manually in a managed device is not automatically adjusted for a scheduled upgrade.

• Schedule upgrade can only be initiated using the upgrade-profile.

Configuring a Scheduled Upgrade

To configure a scheduled upgrade, perform the following steps either through WebUI or CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions.:

To configure a scheduled cluster upgrade, refer to the Scheduling Upgrade of Clusters section.

The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command schedules a scheduled cluster upgrade:

Parameter	Description
