Creating device CRGs
A device cluster resource group (CRG) is made up of a pool of hardware resources that can be switched as an entity. To create switchable devices within a high-availability solution, the nodes that use these devices need to be a part of a device CRG.
Prior to creating a device CRG, add all nodes that will share a switchable resource to a device domain.
To create a device CRG, use the Create Cluster Resource Group (CRTCRG) command and specify *DEV for the CRGTYPE keyword.
