Detailed Description

The Update-SCXAgent cmdlet updates the agent on the specified computers to the latest version available. If the latest available version of the management agent is already installed a targeted computer, no action is taken.

The required Agent parameter specifies the targeted managed UNIX and Linux computers to uninstall and requires a UNIX and Linux computer object. For information about retrieving managed UNIX and Linux computers, type Get-Help Get-SCXAgent. This cmdlet accepts SshCredential and WsManCredential input parameters. The supplied SshCredential parameter is used for privileged agent update actions while the supplied WsManCredential is used for low-privileged agent communication. If the SshCredential parameter is not provided, the cmdlet attempts to use the defined agent maintenance Run As account associated with the targeted computer.

The output of this cmdlet is an array of managed UNIX or Linux computer objects representing the targeted systems that were successfully updated.

Parameters

-Agent<IPersistedUnixComputer[]>

Specifies one or more managed UNIX or Linux computer objects. For information about how to get a managed UNIX or Linux computer object, type Get-Help Get-SCXAgent.
