Create Volume Group Wizard: Choose resource group or nodes

start of changeUse this page to specify a resource group to which to add the volume group. Alternatively, select the nodes to which the disks attached to those nodes can be used to be part of the volume group. end of change

Fields

You can choose either of the following options as part of configuring the volume group:

Choose resource group to add the volume group to
Select an existing resource group to which to add the volume group. You can select any resource group from the list of discovered resource groups in the cluster. If you select a resource group, all its nodes are selected for you in the nodes list and you cannot change the node selection.
If you select a resource group that has a startup policy of Online On All Available Nodes, this selection affects the choices available for other properties.
Note: To determine the start policy for a resource group, select the resource group on the Resource Groups tab and select the General page to view the policy setting.
start of changeThis startup policy restriction affects the following volume group properties on the Name and Configure Volume Group page:
  • The volume group is set to allow concurrent access. You can change this property to the Critical concurrent access option, but not to the Fast disk takeover option.
  • start of changeBecause the volume group is set to allow concurrent access, the volume group type cannot be scalable and you can configure only the Physical partition size property. You cannot configure the Maximum number of partitions or the Maximum number of logical volumes properties. Nor can you enable mirror groups for the volume group. end of change
end of change

start of changeAdditionally, on the Configure Logical Volumes and File Systems page, cannot configure a file system for logical volumes in the volume group. Concurrent access mode does not support the use of file systems due to the potential for data divergence problems.end of change

Choose two or more nodes
start of changeSelect two or more nodes to which the disks attached to selected nodes can be used to be part of the volume group.end of change The table lists all discovered nodes within the chosen cluster. The format for each node name is nodename.hostname, where hostname is the fully qualified host name of the system on which the node is located. If you select nodes, you cannot select a resource group. start of changeUsing this option, you can create the volume group and later add it to an existing resource group.end of change
Note: start of changeFor clusters that have sites configured for them, the node name ends with @sitename to indicate the site location of the node.end of change
