Memory: CLI Rules for Dynamic Migration of Memory

Please note the following CLI (Command Line Interface) rules for online migration of memory and CPUs

while the target partitions are up. Note that because the following applies only to online migration (in other

words, where the target partition is up), it does not apply to the vparcreate command, where the target

virtual partition should never be up during the vparcreate invocation.

• In the same command, you cannot have an online addition and online deletion. For example, the following

are illegal:

— keira1# vparmodify -p keira2 -a cpu::2 -d cpu::1

— keira1# vparmodify -p keira2 -a mem::1024 -d mem::512

You must specify each change on a separate command line. For example, the following are allowed:

— keira1# vparmodify -p keira2 -a cpu::2

keira1# vparmodify -p keira2 -d cpu::1

— keira1# vparmodify -p keira2 -a mem::1024

keira1# vparmodify -p keira2 -d mem::512

• In the same command, you cannot make changes to both memory and CPU. For example, the following is

illegal:

— keira1# vparmodify -p keira2 -a cpu::2 -a mem::1024

• In the same command, you cannot make changes by both address and ILM or both address and CLM. For

example, the following are illegal:

— keira1# vparmodify -p keira2 -a mem::1024 -a mem:::0x40000000:256

— keira1# vparmodify -p keira2 -a cell:6:mem::1024 -a mem:::0x40000000:256

• In the same command, you can specify both ILM and CLM changes. For example, the following are

allowed:

— keira1# vparmodify -p keira2 -a mem::1024 -a cell:6:mem::1024

• In the same command, you can migrate both base and ﬂoat memory. For example, the following are

allowed:

— keira1# vparmodify -p keira2 -a mem::512:b -a mem::512:f

— keira1# vparmodify -p keira2 -a mem::512:b -a cell:0:mem::512:f -a cell:2:mem::1024

Memory: Allocation Unit Notes

• The default memory assigned to a virtual partition is 0 MB, so you need to specify enough memory for

your applications and the operating system. Please see the Install and Upgrade Guide for your OS and

the nPartition Administrator’s Guide for your server.
