Installing the Server Software for SCO UNIX
For SCO UNIX, the additional HP Remote Assistant software you install on each SCO
UNIX server includes:
•
HP Automatic Server Restart
Automatic Server Restart (ASR) eases the burden of dealing with a system crash or
hang by automatically restarting the system if such a failure occurs. A
combination of software and hardware is used to do this. When ASR is enabled,
the ASR software periodically notifies the ASR hardware that the system is
running correctly. When the system crashes or hangs, the ASR hardware is no
longer notified and will automatically restart the system after a pre-configured
amount of time. The system must be configured to successfully restart without user
intervention.
Not all system hangs will cause a system restart. For example, if the network
operating system is still functional, yet all forms of user input have been disabled
due to error (giving the appearance of a system hang), then ASR will not cause a
system restart.
In addition to its other capabilities, the HP Remote Assistant provides ASR
hardware for systems that do not have it built in and extends the ASR capabilities
for all systems. It captures the last screen as the system hangs which usually
contains critical troubleshooting information. It also logs system restarts for later
review and has the ability to page when the system restarts.
Note that ASR should be installed on each SCO UNIX server that has an HP Remote
Assistant accessory.
Setting Up ASR for SCO UNIX
This section describes the program files you need to install ASR for SCO UNIX and
provides instructions for installing, deinstalling, reinstalling, configuring, and
executing ASR.
The SCO UNIX ASR files must be installed using the supplied disk (HP Remote
Assistant SCO UNIX ASR Driver Diskette) and the Custom Install facility of SCO
UNIX. The disk is in tar format and is a Custom Install distribution floppy. The
process for installing is the same as any other SCO UNIX driver installation.
