# Configuring a Maintenance Window in Air Gap for HyperScale X

You can set a maintenance window at a specific time to perform planned tasks (such as adding new nodes and upgrading the operating system) that require network connectivity between Vault HyperScale X nodes and the CommServe server.

During this interval, the Airgap HyperScale X nodes temporarily lift the air gap and maintain a continuous network connection with the CommServe server.

After completing the planned tasks, you can cancel the maintenance window to re-enable the air gap in few minutes time.

Log in to any HyperScale node in the cluster as cvbackupadmin user and execute the commands in this section.

## Set a Maintenance Window Starting Immediately

To set a maintenance window for a specified duration starting immediately, run:

    hs_cluster --lift_airgap window=<duration in minutes>

Example:

    hs_cluster --lift_airgap window=120

## Schedule a Maintenance Window for a Specific Time

To schedule a maintenance window for a specified duration from a specific date and time, run:

    hs_cluster --lift_airgap startdate=<yyyy-mm-dd> starttime=<HH:MM> window=<duration in minutes>

Example:

    hs_cluster --lift_airgap startdate=2024-06-11 starttime=15:00 window=120

Note

Only one maintenance window can be active at a time. The latest configuration takes precedence.

## Cancel a Maintenance Window

To cancel an active maintenance window, run:

    hs_cluster --lift_airgap window=0

Note

Setting the duration to 0 minutes returns the nodes to air gap mode in few minutes and cancels the maintenance window.
