Table 96. Contents of the Update Package

File Name	Description
CMM_RB.bin	Redboot image to be stored in flash
CMM_FPGA.bin	FPGA image
CMM_FFS.bin	/etc image
CMM_OS.bin	OS image
README	Text file containing release notes for the update package
Update_Metadata	File containing info on the update package and how it should be installed on the CMM
Utilities	Sub-directory containing any utilities that might be required for the install.
validationfile	File containing MD5 checksums for the files and scripts present in the update package.
saveList	List of configuration files in /etc to be preserved across software updates.
Other	Other components such as FRU files that may be necessary for the update.
version_history	List of all versions of firmware available for the platform in sequential order, with the
	newest versions at the end of the list.
mpcmm0001.mib	MIB file for SNMP.

The update package can be placed locally on the CMM in the /usr/local/cmm/temp directory, or it can reside on a server on the network.

The files and directories that make up the Update Package are packaged and delivered as a .zip file. Associated with the .zip file is a file containing the md5 sum of the .zip file. For example:

•[PackageFileName].zip file containing all files and subdirectories of the update package

•[PackageFileName].md5 file containing md5 checksum of PackageFileName.zip

Arguments for the location of the update package will be given in the CLI command, which can be used to point to a remote server or a local directory. The update script will then remove the /usr/ local/cmm/temp/update/package directory and recreate it with the new package files.

Note: If an NFS server is mounted to the CMM, the argument in the update script will be similar to a file located locally on the CMM.

If the package fails to copy or transfer to /usr/local/cmm/temp/update/package, then the update process will terminate.

23.4.1Update Package File Validation

The first level of update package validation is checking that the md5sum of the zip file matches the md5sum in the [PackageFileName].md5 file of the update package.

Update packages are validated during the update process by computing the md5sum of each file and comparing against the checksums stored in the checksums stored in the validation_file included with the update package.

The update package is also checked to ensure it is valid for the platform where it is being used. For example, an update package with firmware for a CompactPCI* CMM will not work on an AdvancedTCA* CMM.
