Configuring VCS service groups to manage the LPAR
You must configure a VCS service group to manage the LPAR.
To configure LPAR service groups
- Create a failover service group for LPAR.
- Set the PhysicalServer attribute of all the systems (which are management LPARs) using the name of the physical server (managed system name).
- Set SysDownPolicy = { "AutoDisableNoOffline" } for this group.
- Configure all the cluster nodes (management LPARs) in the SystemList attribute where the managed LPAR can fail over.
- Configure LPAR resource for the managed LPAR.
The sample main.cf for a VCS failover cluster for managed LPARs:
include "types.cf" cluster cluster01 ( ) system aixnode55mp1 ( PhysicalServer = sys1 ) system aixnode56mp1 ( PhysicalServer = sys2 ) group LPAR_aixnode5556mp2 ( SystemList = { aixnode55mp1 = 0, aixnode56mp1 = 1 } SysDownPolicy = { AutoDisableNoOffline } ) LPAR aixnode5556mp2 ( LPARName = aixnode5556mp2 MCUser = { hscroot, hscroot } MCName = { hmc6, hmc7 } VIOSName @aixnode55mp1 = { aixnode55vio1, aixnode55vio2 } VIOSName @aixnode56mp1 = { aixnode56vio1, aixnode56vio2 } RestartLimit = 1 )
