When the switch reboots, it checks the install information in a strict order:
• Firstly, the switch checks the temporary install. If a temporary install is
specified, the switch loads it into RAM and runs it. At the same time, it
deletes the temporary install information so it will not load a second
time. This information is deleted even if the temporary install triggers a
fatal condition causing the switch to reboot immediately.
• Secondly, if no temporary install is defined, or the install information is
invalid, the switch checks the preferred install. If present, this install is
loaded. The switch never deletes the preferred install information.
• Thirdly, if neither a temporary install nor a preferred install is specified,
the switch loads the default install. The default install is always present
in the switch because if, for some reason, it is not, the INSTALL module
will restore it.
The preferred install should not be set up with an untested release or patch. It
is advisable to install new releases or patches as the temporary install, and
when the switch boots correctly, to then set up the preferred install with the
new release or patch.
To change the install information in the switch, enter the command:
SET INSTALL={TEMPORARY|PREFERRED|DEFAULT}
[RELEASE={ release-name |EPROM}] [PATCH= patch-name ]
For security reasons the SET INSTALL command is only accepted if the user has
SECURITY OFFICER privilege.
When you set a patch file as part of a temporary install or permanent install,
you must also set the corresponding release file in the same command, if it has
not already been set as part of that install. You can set the patch, but not the
release (always EPROM), for the default install.
To delete a temporary install or preferred install, enter the command:
DELETE INSTALL={TEMPORARY|PREFERRED}
If a default install is set, only the patch information is deleted using the
DELETE INSTALL command as the release information must always be left
intact in the default install.
To display the current install information, including which install is currently
running in the switch, and how the install information was checked at the last
reboot, enter the command:
SHOW INSTALL

the Rapier Series Switch Software Reference .
