loaded. At the same time, the temporary install information is deleted. This
ensures that if the switch reboots immediately as the result of a fatal condition
caused by the temporary install, the temporary install will not be loaded a
second time.
If there is no temporary install defined, or the install information is invalid, the
preferred install is inspected. If present, this install is loaded. The preferred
install information is never deleted.
If neither temporary nor preferred installs are present, the default install is
used. The default install will always be 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, use the command:
SET INSTALL={TEMPORARY|PREFERRED|DEFAULT}
[RELEASE={release-name|EPROM}] [PATCH[=patch-name]]
The INSTALL parameter specifies which install is to be set. The INSTALL
module is responsible for maintaining install information and loading the
correct install at boot. An install is a record identifying a release and an optional
patch. Three installs are maintained by the INSTALL module, temporary,
preferred and default.
The default install is the install of last resort. The release for the default install
can not be changed by the manager and is always the EPROM release. The
patch for the default install may be set by the manager.
The temporary and preferred installs are completely configurable. Both the
release and an associated patch may be set. The release may be EPROM or a
release stored in FFS.
The RELEASE parameter specifies the release file for this install. The release
file is either a file name of the form
device:filename.ext for files in the file
subsystem, or EPROM, to indicate the EPROM release. The default value for
the device field is FLASH.
The PATCH parameter specifies the patch file for this install, and is a file name
of the form
device:filename.ext . The patch file is stored in FLASH. The
default value for the device field is FLASH . If the patch name is not given, the
patch file information for a given install is removed and only the release file
will be loaded for the install.
A patch file can not be set up for an install unless a release file is already set up,
or a release file is specified in the same command. This stops the inadvertent
setting of an install to be just a patch file. When the switch reboots in such a
case the particular install is ignored, which may have undesirable effects on the
switch operation.
For security reasons this command will only be accepted if the user has SECURITY
OFFICER privilege.
