23.3Critical Software Update Files and Directories

The following table is a list of files and directories important to the software update process.

Table 95. List of Critical Software Update Files and Directories

File or Directory Name:	Description:
/usr/local/cmm/temp	Mount point for ramdisk
	Directory into which the update package is copied and unzipped.
	The update process will delete and recreate this directory. If it is
	desired to copy the update package to the CMM before updating,
/usr/local/cmm/temp/update/package	then put the package in /usr/local/cmm/temp/update.
	NOTE: Do NOT place the update files into the /usr/local/cmm/
	temp/update/package directory. The update process uses
	this directory and will erase and overwrite files placed
	here.
/usr/local/cmm/temp/update/etc	Backup copy of /etc is located here
[package file].zip	Zip file containing update package files
[package file].md5	MD5 checksum of the [package file].zip file
/etc/versions	At the end of an update, this file contains a list of the package
	version, and each component version
	The update process will move the "old" /etc/versions file by
/etc/versions.<version>	appending a file extension to it which is the package version string
	- i.e., .. /etc/versions.5.1.0.0117
	These optional scripts are supplied by the user. The update
	process will execute them just prior to shutting down the cmm
/home/update/scripts/K*	applications. The primary function of these scripts is to allow the
	user a method of shutting down any user process which are using
	the flash file systems.
	These optional scripts are supplied by the user. The update
/home/update/scripts/S*	process will execute these scripts just before processing the save
	list - which copies files and directories from /usr/local/cmm/temp/
	update/etc to /etc
/home/update/backup	If the update direction is "backward", then files and directories that
	are priority 2 will be copied here instead of /etc
/usr/local/cmm/temp/update/update.log	Log file to which output is sent while the update process is
	operating - this is on a ramdisk.
/etc/cmm/update.log	The log file is copied when the update process completes
	successfully.
