HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)

The explicit specification of an LBA on a non-nPartitionable system consists of two

fields: sba/lba

2. The explicit specification of an LBA on an nPartitionable system consists of three fields:

cell/sba/lba

3. With A.03.02 and later and A.04.xx, all LBAs under a SBA are implied when explicitly

specifying a SBA without specifying any LBA. Therefore, the path specified on a

command line can have different meanings depending upon the vPars version, the type

of server, and the user intent. For example, the path of x/y can mean any of the

following:

— sba=x, lba=y on a non-nPartitionable server running vPars A.03.01 or earlier.

— sba=x, lba=y on a non-nPartitionable server running vPars A.03.02 or later or A.04.xx.

— cell=x, sba=y on an nPartitionable server running vPars A.03.02 or later or A.04.xx.

• Supported I/O Check your hardware manual to verify that your mass storage unit can be

used as a bootable device. If a mass storage unit cannot be used as a boot disk on a non-vPars

server, it cannot be used as a boot disk on a vPars server. vPars does not add any additional

capability to the hardware.

For information on supported I/O interface cards and configurations, see the document

HP-UX Virtual Partitions Ordering and Configuration Guide.

Memory: Concepts and Functionality

Acronyms

ILM Interleaved Memory

vPars A.03.xx and A.02.xx use and assign only ILM; vPars A.04.xx allows use of ILM and

CLM.

Assignments

You assign memory to a virtual partition:

• by size

This uses the nPartition’s ILM.

Within the available nPartition’s ILM, you can also:

• specify an address range to use

This does not increase the amount of memory assigned to the virtual partition. The address

range is a specific subset of the existing ILM amount assigned to the virtual partition.

Therefore, the total amount of memory specified by ILM addresses cannot exceed the amount

of ILM assigned to the virtual partition.

NOTE: The virtual partition must be in the down state to add or delete memory resources.
