Update Package
The update package is available at:
http://www.intel.com/design/network/products/cbp/atca/mpcmm0001.htm
It contains the components listed in
MPCMM0001 Chassis Management Module Software Technical Product Specification
Download from Www.Somanuals.com. All Manuals Search And Download.
Description:
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,
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.
Backup copy of /etc is located here
Zip file containing update package files
MD5 checksum of the [package file].zip file
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
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
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
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
If the update direction is "backward", then files and directories that
are priority 2 will be copied here instead of /etc
Log file to which output is sent while the update process is
operating - this is on a ramdisk.
The log file is copied when the update process completes
successfully.
