ipt001 up running disabled pst001
ipt002 up running enabled pst001

NODE STATUS STATE
pst002 up running

PACKAGE STATUS STATE AUTO_RUN NODE
ipt003 up running disabled pst002
ipt004 up running enabled pst002

There are two VSP machine (pst001 and pst002)

Each VSP machine running with 2 hpvm configured in cluster

HPVM version is 4.30

Now I need to move the ipt001 from pst001 to pst002.

commands are same as moving one package from one node to other node.

please confirm if my steps are correct.

#cmhaltpkg -v -n pst001 ipt002

#cmrunpkg -v -n pst002 ipt002

WIll those above works or any other commands to move hpvm from one node to other node.

Bonjour,

Globally, yes those commands are OK.

Just be aware that :

- Once you have moved ipt002 to pst002 you have to activate the auto_run flag : cmmodpkg -e ipt002 It was activated before you move the VM, so I guess it is a critical VM you want to be automatically moved back to pst001 in case of a failure of pst002 ... or not ?

- When you halt a package there is no need to specify the node on which the package resides. You halt it, that's all.

- Unless you wrote any complementary scripts, cmhaltpkg will not shutdown properly the VM. So I strongly recommand that you shutdown all applications that are running inside the VM before moving it.

Hope this help

Eric
