Overview

Maintenance Mode is automatically launched when the software on the VBrick does not boot. Maintenance Mode runs from a reduced functioning kernel that provides a limited CLI and IWS interface. The Maintenance Mode interfaces provide minimal configuration capabilities. Maintenance Mode can also be used as a means of downloading new firmware. If your appliance enters maintenance mode during or after a firmware download you can simply rerun the download and reset the appliance to return to normal run mode. Maintenance Mode is an operational mode that in which a VBrick runs with a reduced subset of code. It normally happens only when a power failure occurs during a software download. It provides limited capacity of the IWS interface to manage some parameters of the VBrick appliance. Note that security is maintained in Maintenance Mode, so the user must be at administrator level to change the parameters.
