Installing the Host Registration Service
HRS (host registration service) is a service/daemon that simplifies security configuration and allows libraries
to monitor host connections to the library. HRS sends a periodic data pulse through the host's Fibre Channel
HBA (host bus adapter) to the library. The pulse contains the host's WWN (world wide name), host name,
HBA type, and host port connection.
When the library senses the HRS pulse from a host, the data path to the host registers as "Good." This
information is sent periodically over the host Fibre Channel connection.
The default HRS setting re-registers the host every 5 minutes. You can change the re-registration period to
any value between 1 and 255 minutes.
The data path monitored by HRS must experience problems for two period

intervals before a problem is detected and a ticket is generated.
Once HRS is installed, you can get help on a UNIX host by typing:
hrs -h
on the host's command line, and then pressing Enter. There is no help system for the Windows version of
HRS.
If you plan to use FC Host, install HRS on the appropriate hosts. If you do not
Note
plan to use FC Host you can manage your Scalar i2000 without installing HRS.
However, HRS ensures that data path conditioning includes the host portion of
the data path.
The HRS software is available from the ADIC customer service web site, or from your service
representative.
Installing the Host Registration Service for Windows
Install this software on a host computer running the Windows operating system that is attached to the Scalar
i2000. On a Windows system, the re-registration period cannot be changed, because HRS runs as a service
rather than an independent program.
To install HRS on Windows
1
Verify that the Windows host you are configuring has an installed Host Bus Adapter (HBA).
2
Obtain HstRegSrv.exe from your service representative.
3
Select the Windows Start button, and then select Run.
4
Select HstRegSrv.exe.
5
Select OK.
6
Once installation is complete, reboot the system.
HRS executes as a service and launches at boot time.
