Pre- and Post-Exec Commands

✓The pre- and post-execprocesses operate in background mode. Therefore, do not use any interactive commands for the pre- and post-execprocessing.

✓If a command writes any text to stdout, this text is received by the Disk Agent, sent to the Session Manager, and written to the database. A stderr is redirected to /dev/null. You can redirect it to stdout to get error messages logged to the database.

✓The pre- and post-execcommands for an object have to be located on the client where the Disk Agent is running.

✓The pre- and post-execcommands must be executable and specified with the full pathname.

✓You can disable pre- and post-execscripts by adding the line OB2OEXECOFF=1 into the omnirc file on any client.

✓You can secure the client by specifying which Cell Managers are allowed to access the client. Only permitted Cell Managers will be able to execute pre- and post-execcommands on the client. For more information on securing a client, refer to the HP OpenView Storage Data Protector Installation and Licensing Guide.
