ipt002 up running enabled pst001

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.

Hi

Login to the server and halt the Cluster packages individually.

Then move the VM

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
