Memory: Concepts and Functionality
Definitions for Assigning (Adding) Or Deleting ILM or CLM Memory
Physical memory can be divided into two categories: ILM and CLM.
ILM Interleaved Memory, where memory consists of blocks of memory from one or more cells
of the nPartition.
CLM Cell Local Memory, where memory consists of blocks of memory from only a specific cell
of the nPartition.
You can assign memory to a virtual partition by any of the following methods:
• By size.
This uses the nPartition’s ILM. The basic syntax for this is:
-a|d mem:: size
For more information, see “Memory: Assigning (Adding) or Deleting By Size (ILM)” on page 202.
• By cell and a corresponding size.
This uses the specified cell’s CLM. The basic syntax for this is:
-a|d cell: cell_ID :mem:: size
For more information, see “Memory: Assigning (Adding) Or Deleting By Size (CLM)” on page 204.
• By address range.
This uses an address range within the available nPartition’s ILM or cell’s CLM. The basic syntax for
this is:
-a|d mem::: base : range
For more information, see “Memory: Assigning (Adding) Or Deleting By Address Range” on page 205.
Definitions for Dynamically Migrating ILM or CLM Memory
NOTE Dynamic memory migration may require a system firmware upgrade. See the HP-UX Virtual
Partitions Ordering and Configuration Guide for details.
When assigning (adding) or deleting either ILM or CLM to a virtual partition, you can specify the memory as
either base or float.
Base Base memory cannot be deleted from a virtual partition when a virtual partition is up.
When a virtual partition is up, base memory can only be added to a virtual partition. To
delete base memory, the target virtual partition must be down .
When the target virtual partition is down, base memory can always be added to or
deleted.
To specify base memory, you can append :base or :b to the aforementioned assignment
specifications (see below). :base is the default.
