7.7 dlmstart Utility for Starting HDLM
You must perform the following operations after installing HDLM:
•
Load an HDLM alert driver and a filter driver.
• Configure an HDLM device.
• Start the HDLM manager.
The
dlmstart
utility performs the above operations as a batch operation.
If an HDLM alert driver and a filter driver have already been loaded or the HDLM
manager is already running, the relevant operation is not performed.
