Create an external volume in the two storage systems that make up the global-active device environment, and specify settings to use the external volume as a quorum disk.
- Ensure that the two storage systems that make up the global-active device environment and the external storage system in which the volume used as the quorum disk is configured are connected by physical paths.
- Ensure that the volume used as the quorum disk is assigned a port on each of the two storage systems that make up the global-active device environment.
- If you want to use iSCSI to connect with the external storage system, make sure that external iSCSI targets are already registered.
- Identify the following items required to configure the external volume:
- The port to use for external connection
- The model and serial number of the external storage system
- The port information for the external storage system that is
connected with a port for external connections:
- When using Fibre Channel for the protocol you can specify WWN
- When using iSCSI for the protocol you can specify iSCSI target name and IP address
- The LUN of the volume used as the quorum disk
If you use a volume with a size that exceeds 4 TiB, the size of the external volume that is created will be 4 TiB.
- The name of the external volume
- The ID of the external volume group
- The ID of the external path group
- Identify the following information required to configure the quorum disk:
- The ID of the quorum disk
- The models and serial numbers of the paired storage system that shares the quorum disk
- Make sure that the user performing the procedure has been assigned the Storage Administrator (Provisioning) role.
