25.3Critical Software Update Files and Directories
The following table is a list of files and directories important to the software update process.
Table 51. 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.V00.30a | |
|
| |
| 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 | ||
| ||
|
|
