You can create a GAD pair using volumes that have been assigned the Data Retention Utility access attribute.

  • When you create or resynchronize a GAD pair, the access attribute set for the P-VOL is copied to the S-VOL.
  • If you change the access attribute when GAD status is Mirrored or Mirroring, make sure to set the access attribute to both the P-VOL and S-VOLs.
  • Server I/O can be controlled, depending on GAD status and the access attribute.
  • If you set the Data Retention Utility S-VOL Disable attribute on the GAD S-VOL, GAD pair operations using CCI are restricted. Release the S-VOL Disable attribute from the S-VOL, then perform CCI operations.
