hi haqbahu ;

since these vgs activated on db side. you cannot display their status on app side . they are disactivated on app. this is expected behaivour.

If a VG is cluster aware and part of the package then thise vgs will be controlled by package script. This means they will be activated/ deactivated on the respective nodes as per the package.

Another thing is, if a vg is activated in exclusive mode then it can not be activated on other node.

Hi,

If the vg is activated on a node in exclusive mode then other node can not activate this vg.
