Bellow is the guideline and example to set up the hosts and host groups
when using multi-path IO solutions:
•
Independent MPIO Hosts Computers
For independent (non-clustered) host computers sharing single RAID
system, the storage should be partitioned and accessed independently
by the host computers. One host group should be created for each host
computer, and the host group should include all HBA ports on the host
computer. So, each host computer has LUN mappings of its own, and it
can see its LUN mappings from all HBA ports and paths.
Figure 5-26 illustrates two independent servers sharing single RAID system
with multi-path I/O. Each server sees two LUNs (DG0LD0 and DG0LD1 for
Server 1, and DG1LD0 and DG1LD1 for Server 2), each of which has two
paths.
The table below shows the configuration steps for Figure 5-26.
