Configuration Tasks
• Active-Active Redundant Dual MPIO Clustering Hosts (With Fibre/SAS switch)
As Figure 5-9 shows, the redundant RAID system is operating in a clustering environment with dual MPIO hosts and two
FC/SAS switches. Users should be notified that the number of FC/SAS switches, hosts, and controller must be the same
when working in a clustering environment.
Tasks Instructions
Create Virtual volumes and specify the preferred
controller
RAID Management > Disk Groups > Create DG0 and DG1
RAID Management > Logical Disks > Create DG0LD0 >
Specify the preferred controller as ctla
RAID Management > Logical Disks > Create DG0LD1 >
Specify the preferred controller as ctlb
RAID Management > Logical Disks > Create DG1LD0 >
Specify the preferred controller as ctla
RAID Management > Logical Disks > Create DG1LD1 >
Specify the preferred controller as ctlb

Add WWPN of HBAs to hosts HBA0 WWPN -> Host 0
HBA1 WWPN -> Host 1
HBA0 WWPN -> Host 2
HBA1 WWPN -> Host 3
Add hosts to each host group Host 0 and Host 1 -> Host Group 0
Host 2 and Host 3 -> Host Group 1
Assign LUNs to storage groups DG0LD0 and DG0LD1 -> Storage Group 0
DG1LD0 and DG1LD1 -> Storage Group 1
Bind host groups and storage groups to the fibre
ports
Storage Group 0 bound to Host Group 0 -> fcpa2 and fcpb2
Storage Group 1 bound to Host Group 1 -> fcpa1 and fcpb1
