7.4 Determining AlphaServer GS80/160/320 System
Configuration
You may be required to reconfigure an AlphaServer GS80/160/320 system
that is not familiar to you. Before you start to reconfigure any system, you
need to determine:
• The number of partitions in the system
• Which QBBs are in each partition
• Which PCI drawers are used by each partition
• Which PCI drawer is connected to each QBB
• The console serial bus (CSB) addresses
Determine the necessary information with the following system control
manager (SCM) commands: show nvr (Example 7–1), show system
(Example 7–3), and show csb (Example 7–4).
If you are at the SRM prompt, use the escape sequence (Esc Esc scm) to
transfer control to the SCM firmware.
Example 7–3 shows the display for the show system SCM command for an
AlphaServer GS160 system.
