9.2.1.3
Modify Host Affinity
This function performs the following modifications to the existing host affinity.
•
Port Group
•
LUN Group
•
Host - CA Port Connection
Not only the path between the existing host and the CA port, but also the path between a host
and a CA port, which has been added after creating a host affinity, can be modified.
•
The maximum number of host affinities can be created in the ETERNUS DX Disk storage
system is 1024.
•
The maximum number of connectable hosts (the number of HBAs) per port is 256.
Click the [OK] button.
→ The deletion of the host affinity starts.
If the selected host affinity does not exist, an error screen appears.
Click the [Done] button to return to the [Host Affinity] screen.
•
When modifying an active host affinity, make sure to stop the access of
the host which has been associated with the host affinity to be modified.
•
If a specific host group has been selected for a host affinity in the "Host
Group" field, only the port groups with the affinity mode "On" can be
selected.
•
If "All" has been selected for a host affinity in the "Host Group" field, only
the port groups with the affinity mode "Off" can be selected.
•
When one port is registered in several port groups, and the affinity
setting has been configured on one of the port groups including the
corresponding port, the affinity setting is configured on all the port
groups, which include the corresponding port, and also on the member
ports.
•
Port groups without the host affinity setting can be used for creating host
affinity with any host group, regardless of whether the affinity mode for
the host group is enabled (On) or disabled (Off).
