Settings When Using Volumes

This section explains how to create Standard volumes and make them accessible to hosts.
An outline of the settings is provided below.
(1) RAID Configuration Settings
Create a RAID group and a volume.
- Creating RAID groups
Specify a disk drive to create a RAID group.
- Creating volumes
Create a volume in a RAID group.
(2) Host Access Settings
The security of data when multiple hosts are connected can be guaranteed by allocating a host interface
port that can be accessed by the host and a volume that can be recognized by the host. This is why the host
affinity setting is performed.
- Setting host affinity with a host group, a port group, and a LUN group.
• Set the parameter to control the host interface port.
• Register a host that can be used to identify the HBA (Hot Bus Adapter).
• Create a host group (*1).
• Create a port group (*2).
• Create a LUN group (*3).
• Set the relationship between a host group, port group, and LUN group.

Host group
A host group is a group of hosts (HBAs) that have the same interface and access the same LUN groups.
Multiple hosts (HBAs) can be set to one host group. Once the host group is created, the settings of the
hosts (HBAs) can be changed when changing the settings of the host group. The required settings for
each host (HBAs) are simplified and usability is enhanced.
Port group
A port group is a group of ports that have the same port settings. Ports that access the same LUN group,
such as the ports that use multipath connections to servers and the ports that connect servers that
configure a cluster, are set to a single port group. The single port group can be allocated to multiple host
groups. Once the port group is created, all of the ports can be selected at the same time. The required
settings for each port are simplified and usability is enhanced.
