In some cases, volumes that are used for functions other than global-active device can be used with global-active device P-VOLs and S-VOLs.

The following table shows which volume types used for other features can also be used with global-active device P-VOLs or S-VOLs.

  1. A DP-VOL that uses an external volume as a pool volume can be used as a GAD P-VOL or S-VOL.
  2. For the Thin Image node or leaf volume, see the description of the S-VOL, not the P-VOL.
  3. GAD S-VOL is used as a UR delta resync pair P-VOL.
  4. If you set the S-VOL Disable attribute of the Data Retention Utility to the GAD S-VOL, GAD pair operations using CCI are restricted. Release the S-VOL Disable attribute on the GAD S-VOL, and then perform the GAD pair operations.
  5. Quorum disks can only be set on external volumes that are configured so that one external volume group is mapped to one external volume.
  6. You cannot encrypt a nonencrypted quorum disk in the external storage system from the primary or secondary storage system.
