Installation guide

_______________________ Note _______________________
Two parameters of particular importance are the system ID and
the system name. Do not duplicate any system identification or
names of nodes on the star coupler.
C.2 Software Installation and Restrictions
The installation software assists you in identifying and configuring the
components of your system. You should be familiar with the basic
installation guide for your processor before starting the actual installation.
During installation of the Tru64 UNIX software, each accessible MSCP (ra)
disk device must be uniquely identified by its unit plug number as follows:
• The unit plug number must be between 0 and 254, inclusive.
• Each unit plug number must be unique. Two different disks cannot
have the same unit plug number even if the disks are on separate
controllers. For example, if the unit plug number for a disk on
controller A is 5 and the unit plug number for a separate disk on
controller B is also 5, you must change one of the numbers.
• You can connect a disk with a unique unit plug number to two different
controllers (dual or porting). Refer to the
ra
(7) reference page for
information on how to specify the device entry in the system
configuration file.
C.3 Configuration File Entries
The installation software ensures that your HSC components are
configured into the kernel and are included in the /usr/sys/conf/
NAME
system configuration file, where NAME specifies your system name in
uppercase letters.
Chapter 5 provides information on the following entries that correspond to
a CI or HSC configuration:
• Description of the scs_sysid parameter
• CI adapter specifications
• Controller and device specifications
C.4 Booting an HSC Controller or HSC Disk
The Tru64 UNIX software supports booting an HSC disk on the DEC 7000
and DEC 10000 processors. If an HSC controller fails, any disks connected
