A new startup configuration has been added to the list combining the software images given in
the previous command.

The startup configuration created before can be deleted by entering exactly the same com-
mand string preceeded by ‘no’:

(Base Fabric) (Config)#no startupslot 3 config 1 application 2 initrd F kernel F

The ‘show’ command can also be used to display available versions of kernel, initrd, applica-
tions and configurations or all of them. The syntax is:

show startupconfig startup|kernel|initrd|application|config|all

The configuration mode is also used to activate one of the available startup configurations. The
syntax is:

startupslot 3 activate [once]

This command would activate the startup configuration 3 upon next system reset. The optional
parameter ‘once’ would start configuration 3 only once after the next system reset and start the
previously active configuration 1 on following resets. This is used to implement the failsafe up-
grade procedure described below.

Updating Firmware

The firmware - except bootloader and IPMC image - is updated using the CLI. To get a reliable
and failsafe update procedure, the following precautions must be fulfilled:

• Three independent partitions each for kernel and root file system where one holds the

factory default system, one holds system A kernel and root file system and one holds sys-
tem B kernel and root file system. The active system is either system A or system B, the
factory default serves as a backup in case an upgrade of either system A or B fails. See
the flash partition scheme shown above for more detail.

Warning!
It is not recommended to combine images from different releases.
