Advanced Functions
5-3
1. Create virtual disks, like JBOD disks, logical disks, and volumes
2. Choose symmetric storage presentation method
3. Add all HBA ports (with WWPN or SAS address) to the hosts in the
controller
4. Selectively add hosts (HBA ports) to a host group (HG)
5. Export virtual disks to LUNs for the host group (HG)
6. Repeat the previous two steps for each host computer and host group
The hosts mentioned in this manual and the user interfaces of the RAID
systems refer to the HBA ports on the host computers, and host groups
refer to a group of HBA ports. For example, a host computer with two
dual-port HBAs is perceived as four individual hosts by the RAID controller.
Exporting a virtual disk to a host or a host group will allow the HBA port or
the group of HBA ports to access the virtual disks from any of the host-
interface ports in the RAID system.
Note
1. Because a LUN is not accessible during regular initialization, install
the MPIO driver after the regular initialization is done or use
background initialization.
2. Use MPIO management utility to verify that all disk devices and
paths are recognized by the MPIO software.
3. Go to Section 5.2 when using MPIO with redundant-controller
systems.
