4.6 Modify CA Reset Group
This function edits a CA reset group.
All of the ports are configured to be members of one CA reset group on the initial setting. This function can
create a CA reset group with only specific ports or change the member ports of an existing CA reset group
when ports cannot be accessed.
The maximum number of CA reset groups is equal to the number of ports.
• If a host is unable to access the volumes in a port, this function releases the volumes reserved by the
inaccessible port to the ports in the specified CA reset group, without affecting other ports.
• When a port is shared by multiple servers using the host affinity function, only volumes that can be
released under the instructions from the servers are included in the LUN group, with a host affinity
configured with the target server.
• One port cannot be registered in multiple CA reset groups.
• Only the ports with the "CA" or "CA/RA" port mode can be registered in a CA reset group.
• If some ports have been removed from the modification target CA reset group, a different group is created
using those ports. For instance, if ports (Port#2 and Port#3) have been removed from the modification
target CA reset group A (Port#0, Port#1, Port#2 and Port#3), a CA reset group A (Port#0 and Port#1) and a
CA reset group B (Port#2 and Port#3) are created after modification. The minimum number of ports per
CA reset group is one port.
• 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.
• For more details on which servers are required to configure the CA reset group, refer to "FUJITSU Storage
ETERNUS DX Configuration Guide -Server Connection-" for each OS type.
