VG, CVM and VxVM

[steven_serviceguard]

HI,
I am new to serviceguard.
I want to configure serviceguard(version 11.18) for my servers(HP UX 11i). In the package script they specify about VG,CVM and VxVM disk group acivation.
1)Is there any document mentioning when and how to use these?
2)Is it like, out of these only one has be configured depending on th OS or serviceguard?

Hello Steven,

Please check "Managing ServiceGuard" document - http://docs.hp.com/en/B3936-90135/B3936-90135.pdf

Everything is written - how to configure, what disk manager to use (LVM,VxVM...) and so on.

Dear Steven
confusion?????regarding lvm,vxvm,cvm etc..
In addition to configuring the cluster, y can create the appropriate logical volume infrastructure to provide acess to data from different nodeds. This is done with logical volume manager (LVM), veritas volume manager(vxvm), or veritas cluster volume manager(CCM).LVM and VxVM configuration are done before cluster configuration, and cvm configuration is done
after cluster configuration

thanks and regards

See this chapter from the same document - http://docs.hp.com/en/B3936-90117/ch05.html

There are some chapters 'Creating a Storage Infrastructure with ...'.

CVM is only used if you intend to us VxVM in a Serviceguard/Oracle RAC environment. That's quite rare, so unless you need it, you can probably strike that from your line of questions. After that, the package control script will work with either LVM volume groups or vxvm disk groups or both; whichever you decide to implement your disk management with.
