Changing settings using Device Manager - Storage Navigator
Some global-active device (GAD) settings can be changed using
Device Manager - Storage Navigator. This appendix provides instructions for performing these
operations.
The
global-active device (GAD) feature supports read/write copies of the same data in two places at the same time. Its active-active design implements cross-mirrored storage volumes between two matched storage systems accepting read/write I/Os on both sides that are continuously updated.
Global-active device assures that an up-to-date storage volume is always available and enables production workloads on both systems, while maintaining full data consistency and protection. In addition, the use of active-active stretch clustering can also be used for nondisruptive workload migration and nondisruptive data migration, without requiring the use of a separate intermediate system.
After a quorum disk is blocked, you might detect the disconnection of a remote path. You can change the time before the S-VOL pair status changes to PSUE (Block) after disconnection of a remote path is detected in the
Edit Quorum Disks window.
