Utility Commands

ProSafe M4100 and M7100 Managed Switches

delete

This command deletes the supplied image file from the permanent storage. The image to be

deleted must be a backup image. If this image is the active image, or if this image is

activated, an error message displays. The optional

<unit>

parameter is valid only on

Stacks. Error will be returned, if this parameter is provided, on Standalone systems. In a

stack, the

<unit>

parameter identifies the node on which this command must be executed.

When this parameter is not supplied, the command is executed on all nodes in a Stack.

Format

delete

[<unit>] {image1 | image2}

Mode

boot system

This command activates the specified image. It will be the active-image for subsequent

reboots and will be loaded by the boot loader. The current active-image is marked as the

backup-image for subsequent reboots. The optional

<unit>

parameter is valid only in

Stacking, where the

unit

parameter identifies the node on which this command must be

executed. When this parameter is not supplied, the command is executed on all nodes in a

Stack.

Format

boot system

[<unit>] <image-file-name>

Mode

show bootvar

This command displays the version information and the activation status for the current active

and backup images on the supplied unit (node) of the Stack. If you do not specify a unit

number, the command displays image details for all nodes on the Stack. The command also

displays any text description associated with an image. This command, when used on a

Standalone system, displays the switch activation status. For a standalone system, the unit

parameter is not valid.

Format

show bootvar

[<unit>]

Mode

filedescr

This command associates a given text description with an image. Any existing description will

be replaced. For stacking, the

[<unit>]

parameter identifies the node on which this

command must be executed. When this parameter is not supplied, the command is executed

on all nodes in a Stack.

Format

filedescr

[<unit>] {image1 | image2} <text-description>

Mode
