Modify CA Reset Group

Overview

This function modifies a CA reset group.

By default, all of the ports are configured to be members of one CA reset group. This function can create a CA reset group with only specific ports or change the member ports of an existing CA reset group.

The maximum number of CA reset groups is equal to the number of ports.

Caution

  • One port cannot be registered in multiple CA reset groups.

  • Only the ports in the port mode of "CA" or "CA/RA" can be registered in a CA reset group.

Note

  • This function configures a CA reset group to release the volumes reserved by the port that became inaccessible without affecting other ports that do not belong to the CA reset group.

  • If a port is shared by multiple servers using the host affinity function, only volumes that are included in the LUN group, where host affinity with the target server is configured, can be released with instructions by the target server.

  • CA reset groups are required for certain servers to switch clusters correctly.

  • Ports with different CA types can be members of the same CA reset group.
