Configuring a quorum disk by creating an external volume

Use Storage Advisor Embedded to create an external volume in the two storage systems making up the global-active device environment, and specify settings to use the external volume as a quorum disk.

• Ensure that the two storage systems making 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 that is used as the quorum disk is assigned a port on each of the two storage systems making up the global-active device environment.
• Identify the following items required to configure the external volume:
  • The port to be used 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 the Fibre Channel protocol you can specify the WWN.

  • The LUN of the volume used as the quorum disk

    If you use a volume whose size 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 parity 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
