Setting Up, Initializing, and Booting Logical Partitions 4-7
Begin to define logical partitions by issuing commands from the primary console
terminal. Example 4–2 shows a possible sequence. The steps are described
below.
➊
Logical partitions require console firmware support. (See the Systems and
Options Catalog for the version necessary.) If you have not already done
so, verify that your system’s console revision number is the minimum or
greater by issuing the show version command. If the version is not at the
desired level, you need to update the console firmware. Obtain a console
CD with the latest version, and follow the instructions for the Loadable
Firmware Update (LFU) utility, as described in the AlphaServer GS140 or
8200/8400 Operations Manual.
➋
Check to see if any lp_ environment variables have been set for this
system. The example shows none have yet been created. If they had, the
display would have indicated variables and their settings.
➌
Create (or set, if the lp_* environment variables have already been
created) the desired environment variables. Create (or set) the CPU and
I/O masks to the values you want for each of your partitions. The example
shows three partitions. Use whatever values needed for your partitioning
scheme, as described in detail in Chapter 3.
➍
Issue a show lp* command to check the settings. If any mistakes were
made in the settings, correct them at this point.
➎
Set the boot_reset environment variable to off. This is necessary so that
booting a partition does not interfere with the operation of other,
previously booted, partitions. If boot_reset were on, then a system-wide
reset is done when the boot command is executed from any partition. This
reset will immediately terminate operation of all partitions.
➏
Set the interleave environment variable to none.
➐
Set the environment variables pertaining to partition 0. In this case. the
os_type and auto_action environment variables are set.
➑
Issue an init command to restart the system with the new environment
variable settings.
