The procedure to create a SAS host group is as follows:
Procedure
1 Click [Add SAS Host Group] in [Action].
2 Input a host group name to be created, and select a host response to be assigned to the
host group.
• Host Group Name
Specify the host group name.
An existing host group name cannot be specified. Refer to "Naming conventions for adding hosts"
(page 994) for details.
The following input conditions apply:
- Up to 16 alphanumeric characters and symbols (except ", (comma)" and "?")
- Space
• Registration of the host is necessary to create a host group. Create a new host group when registering a
host with GUI by using this function.
• A host can be a member of several host groups. However, only one LUN group can be allocated to host
and port combinations when configuring host affinity.
• To assign an appropriate host response to a created host group, refer to "User's Guide -Server Connection-
" for each OS type. The host response configures the operation mode that is appropriate for the host.
If an appropriate host response is not configured to the host group, the path may not be switched
correctly or the volume may not be recognized correctly.
• The host response that is specified for a host group is applied all the member hosts in the target group.
When a host belongs to multiple host groups, the same host response must be applied for all the groups
to which the target host belongs. When a host that already belongs to an existing host group is added to
a newly created host group, the host response of the new host group is applied to the host. The host
response of the existing host group to which the target host belongs is also changed. Refer to "Example
of changing the host response when adding a host group" (page 447) for details.
• The name of the [Add SAS Host] function, which creates a new SAS host group and registers the member
hosts has changed with firmware version V10L50. The [Add SAS Host] function is now called the [Add SAS
Host Group] function.
• To change the settings of the host groups, use the procedure in "9.2.2.5 Modify Host Group" (page 463).
• To add a port to an existing host group, use the procedure in "9.2.2.5 Modify Host Group" (page 463)
.
• To change the host name or the SAS address, use the procedure in "9.2.2.17 Modify SAS Host" (page 514)
