Installation guide

• Adding or removing system hardware components (CPUs, memory,
IOPs, PCI busses, IO controllers, and IO devices [except for hot
swappable disks]).
• Changing any partition’s hardware resource assignments by modifying
any console EV with lp_ prepended to its name.
• Running the ECU (Eisa Configuration Utility) or the RCU (Raid
Configuration Utility) from the floppy disk drive.
E.4.7.1 Interfacing with Compaq Customer Service
If you need to escalate a problem to Compaq Customer Services, it is
important that you make the Customer Services representitive aware that
the system is partitioned (particularly when the service is performed via
remote diagnosis). When you place the service call, state that your system
is using logical partitions.
The logical partitioning software provides two methods for the customer
services representitive to determine whether or not a system is partitioned.
The LP_INFO messages printed during operating system startup are also
entered into the binary error log as part of the Startup ASCII Message.
The sizer -P command can be run on any instance of the operating
system and will display the partitioning status of the system as follows:
# sizer -P
Host
hostname is instance 1 of 2 partitions.
Physical memory starts at address 0x80000000.
Memory mode is isolate.
Processors assigned to instance 1: 4 5 6 7
IO Port (s) assigned to instance 1: slot 7
If the system is not partitioned, the following message is displayed, where
hostname is the name of the system:
Host hostname is not partitioned.
E.4.7.2 Performing Hardware Management and Maintenance Tasks
Before performing any management or maintenance tasks, you must
terminate operation of all partitions and return the system to an
unpartitioned state. Use the following steps to shut down partitions:
1. Shut down the operating system in each partition.
# /usr/sbin/shutdown -h +5 "Shutting down for maintenance"
2. Disable partitions by executing the following command at the primary
console terminal:
P00>>>set lp_count 0
