Pre- and Post-Exec Commands
Chapter 5262
✓ The pre- and post-exec processes operate in background mode.
Therefore, do not use any interactive commands for the pre- and
post-exec processing.
✓ 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-exec commands for an object have to be located
on the client where the Disk Agent is running.
✓ The pre- and post-exec commands must be executable and specified
with the full pathname.
✓ You can disable pre- and post-exec scripts 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-exec commands on the client. For
more information on securing a client, refer to the HP OpenView
Storage Data Protector Installation and Licensing Guide.
