Generating and using the MD5 checksum

At the beginning of any operation involving epkg formatted images, emgr looks on the system for a supported command that generates an MD5 checksum. If a command is located, emgr executes this command and displays the resulting MD5 checksum.

You can then cross check this MD5 checksum with a secured source. If a command is not located, emgr takes no further action. You can force set an explicit path to a command that generates a checksum by exporting the EMGR_MD5_CMD shell variable. This variable should contain the absolute path to the command. emgr does not verify that the user set command in the EMGR_MD5_CMD variable is an actual command that generates an MD5 checksum. The syntax used by emgr to generate the MD5 checksum is as follows:
$EMGR_MD5_CMD epkg image file
The expected output is the MD5 checksum as the first word in the output.
Note: This feature is not supported in the original release of interim fix management. You should update to the latest level of interim fix management to enable this feature. To update interim fix management, update bos.rte.install to the latest level.
