SYSTEM ADMINISTRATION
CHAPTER 4: SYSTEM ADMINISTRATION
The table below describes the options available to you depending on the State and Use of
the software images.
The system will automatically reboot during the transition from UPGRADING to FALLBACK
and the transition from READY TO UPGRADE to UPGRADING because a new software
image needs to be loaded in order to complete these transitions.
Existing Images Table
Filename:
This table displays either one or two filenames. If the value
displayed in the Software Upgrade process state table is
“INITIAL” then this is the initial software installation and only one
filename is displayed. In all other cases two filenames are
displayed.
Use:
The values displayed in the Use column depend on the state of
the system. (See
Table 4–21:: Software Upgrade States
.)
