9.2.2.11 Add SAS Host
This function registers a new SAS host (HBA).
The total number of all the interface type hosts that can be registered in the ETERNUS DX Disk storage system
is 1024.
The procedure to register a SAS host is as follows:
Procedure
1 Click [Add SAS Host] in [Action].
Click the [Continue] button to continue registering iSCSI hosts.
• This action item is only displayed when the "Use "Add Host"" checkbox is selected for the "Function to Add
Host" field in "Web GUI Settings". This item is not selected (not displayed) by default. Refer to "11.2.13.4
Setup Subsystem Parameters" (page 935) for details.
• Note that this function does not create a host group. The ETERNUS DX Disk storage system also has a
function that creates new host groups to register hosts as its members. Refer to "9.2.2.3 Add SAS Host
Group" (page 456) for details.
• Hosts that are registered with this function can belong to multiple host groups. However, only one LUN
group can be allocated to host and port combinations when configuring host affinity.
• Refer to "User's Guide -Server Connection-" for each OS type to assign an appropriate host response to the
host that is to be registered. The host response configures the operation mode which is appropriate to the
host.
If an appropriate host response is not configured, the path may not be switched correctly or the volume
may not be recognized correctly.
• To change the SAS host information, use the [Modify SAS Host] function. Refer to "9.2.2.17 Modify SAS
Host" (page 514) for details.
• The host affinity setting can be specified for each SAS host. Refer to "9.2.1.1 Create Host Affinity" (page
414) for details.
