HS-Series Agent Interaction
If you have an HSZ22 controller connected to a system, the HS-Series Agent
for Tru64 UNIX and Windows NT will identify the HSZ22 controller as an
HSZ20 whenever it scans for subsystems. These Agents scan for subsystems
in two instances. One is during the installation of Tru64 UNIX or Windows
NT. The other instance is when you request that an Agent scan for subsystems.
There are two ways to handle this interaction:
■ Avoid the problem - Shut off the HSZ22 controller during the HS-Series
Agent installation. After the installation, turn on the HSZ22 controller
and reboot the system.
■ Repair the problem - During the installation of the HS-Series Agent,
delete the erroneous entry. The installation runs the Agent configuration
utility. The second screen of the configuration utility lists the
subsystems found during the installation. The HSZ22 entry can be
identified by its serial number, by its firmware version, and by the drive
used to access the subsystem.
Troubleshooting Connection Problems
This section documents known connection problems and suggests some
solutions. SWCC is a TCP/IP socket-based application. As a result, SWCC
requires that each node running a SWCC Client or Agent must have access to
a valid hosts file or Domain Name Service (DNS) server. The valid hosts file
must include at least the system itself and any other systems running a SWCC
Client or Agent that it will connect to.
Make sure the system names used for the Client and Agent match each other
consistently. As a general rule, always use lowercase letters when entering
names.
Access Denied Problem
This section covers some of the most common reasons for a Client to receive
an “Access Denied” message when it attempts to add an agent system to the
Navigation Tree.
