ExtremeXOS 12.3.4 Release Notes

install firmware verify

install firmware verify {abort-on-error}

Description

Installs the firmware bundled with the ExtremeXOS image on BlackDiamond 20808 switches and checks

status before and during installation.

Syntax Description

Default

When the abort-on-error option is not specified, any module that fails during upgrade is skipped and

the installation process continues with the next module.

Usage Guidelines

On BlackDiamond 20808 switches, use the install firmware verify command to install firmware on

the MMs, I/O modules, fabric modules, and the fan tray (through the PFC).

This command differs from the

install firmware command in the following ways:

● It performs a pre-installation check to see that all modules are operational before starting the actual

upgrade and asks for user confirmation to proceed after the check.

● While upgrading the modules, it ensures that a currently upgraded module comes back to an

operational state before starting the upgrade of the next module. If a module becomes faulty during

an upgrade, it reports the error to the user and continues with the next module, leaving the faulty

module as it is.

● In a dual MM system, before upgrading the firmware on the master MM, it ensures the other MM is

in backup and in-sync mode so that the reboot of the master module while upgrading its CFG FW

will not lead to a whole system re-boot. Instead, a backup in-sync will take over.

● It takes more time because the system waits for every module to become operational after the

firmware upgrade.

With the

abort-on-error option, if any module becomes faulty while an upgrade is in progress, it will

abort the install steps and exit leaving any remaining modules untouched.

Example

The following command installs the newer firmware image and checks for status:

install firmware verify

Following is sample output from this command:

(debug) BD-20808.4 # install firmware verify

abort-on-error Specifies that the upgrade process is to abort and exit if any module fails

during upgrade.
