E.4.6.7 Logical Partitioning Informational Messages at Boot Time
If logical partitions are set up and enabled, several informational messages
will displayed by the operating system on the console terminal for each
partition near the beginning of the bootstrap process.The following example
shows typical messages for a two partition system:
Partition 0
-----------
LP_INFO: 2 partition(s) established via lp_count
LP_INFO: primary processor for partition 0 is CPU 0
LP_INFO: partition 0 CPU allocation mask = 0xf
LP_INFO: partition 0 IOP allocation mask = 0x100
LP_INFO: Memory partitioning mode set to isolate
LP_INFO: partition 0 memory starting address = 0x0
Partition 1
-----------
LP_INFO: 2 partition(s) established via lp_count
LP_INFO: primary processor for partition 1 is CPU 4
LP_INFO: partition 1 CPU allocation mask = 0xf0
LP_INFO: partition 1 IOP allocation mask = 0x80
LP_INFO: Memory partitioning mode set to isolate
LP_INFO: partition 1 memory starting address = 0x80000000
These messages provide the following information:
• The number of active partitions
• The number of the primary processor for the current partition.
• Which processors are allocated to the current partition.
• Which IO port modules are allocated to the current partition.
• The memory partitioning mode (should always be set to isolate).
• The starting address of memory for the current partition.
E.4.7 Hardware Management and Maintenance
For the AlphaServer GS140, partitions share a common physical enclosure
and hardware (such as power supplies, system bus, and control panel
power switch). The following hardware management and maintenance
tasks cannot be performed on individual partitions. You must disable
partitions and reset the system to a unpartitioned state.
Tasks that require a complete system reinitialization are:
• Performing corrective or preventive maintenance on system hardware.
• Installing AlphaServer GS140 firmware upgrades, including IO
controller firmware upgrades.
