20 Scalar Firewall Manager
Host Registration Service
The Host Registration Service (HRS) is a small service/daemon installed on hosts which access the library.
HRS simplifies security configuration and allows administrators to monitor host connections to the library.
To accomplish this, HRS sends a periodic data pulse through the host’s Fibre channel HBA to the library.
The pulse consists of the host’s WWN, network name, HBA type, and HBA driver level. The SNC records
this information and displays it in the AMC.
This information is used to simplify configuration of the embedded firewall, SFM. Instead of manually
associating an HBA WWN with a specific host, the Scalar Firewall Manager, SFM, is configured using well
known host names. HRS is also used to monitor the status of hosts connected to the library. When the SNC
receives a HRS pulse from a host, the host is displayed in the AMC as online. If the SNC does not receive
two consecutive HRS pulses, the host will be listed as offline.
The SFM database contains separate fields to store the WWN, host name, host type, connection, host
status and a LUN Access field that holds information about LUNs assigned to it.
When the SNC is first booted, SFM initially treats all hosts as “offline” until a host sends an I/O request to
the SNC. SFM detects the I/O and obtains the WWN of the HBA or Initiator. If the WWN is already in the
database (already registered), SFM stores the value “online” in the status field.
If the WWN is not in the database, SFM adds it and stores the value “online” in the status field. SFM sets
the default value for each of the other parameter fields to “unknown”.
At this point, SFM has registered the HBA or Initiator but has minimal information about it. The system
administrator can proceed to complete the registration by using the SNC to manually enter the “unknown”
host information and assign access privileges to LUNs.
Installing the Host Registration Service
The Host Registration Service software is included on the CD that shipped with the SNC.
1 Insert the SNC software CD into the host.
2 Browse to the client software directory.
3 Open the directory for your Operating System and open the readme. This file lists specific instructions
for installing the package.
4 Install the package.
5 Reboot the server.
6
(
Optional) Configure security for the SNC, channel zoning, and/or the Scalar Firewall Manager. For
definitions and specific instructions, see the ADIC Management Console User’s Guide .
Once installed, the service runs automatically and does not require further system administrator interaction.
From the ADIC Management Console, you can see the Fibre Channel that the host is connected to and you
can tell whether the host is online or offline. For software updates, visit “Service and Support” at
www.adic.com .
Note
The AMC view must be refreshed to see status changes for hosts.
CAUTION
If SFM is not enabled, hosts will not appear in the AMC.
