Confirm the Space of File System
The user may use "show file system" or "dir" command to learn the space and its
usage of the existing file system.
If the target file system has sufficient space to store both new and old program
images, then during the upgrade process, the original boot/main program will be
renamed as "original filename.bak". When the CTRL version is 10.4 or above, this
file will be used as the backup image of new program image. When the new program
image fails, the system will boot with this back image. This can save the rollback
operation required in the case of upgrade failure.
When the system has hardly any residual space, the user will need to clean up the
file system in order to make sure the upgrade is successful. Unnecessary files can
be deleted using "del" command. While upgrading the chassis device with dual
management boards, the file system space of the slave board shall also be verified.
The URL prefix of file system space of the slave board is "slave:".
When file system space is insufficient to store two program images,
the backup file of original program image will not be generated.
