5. Enter the data from step 4 on page 204 into the window shown in Figure 4-71.
Figure 4-71 Define Host: Specifying the host name and HBA
– Select your interface type (FC in our example) and an active port already detected by
the DS subsystem, or type its world-wide port name directly into the field.
– Type an alias for the specified host port identifier and click Add.
– Repeat the same process until you define all the HBAs. Remember that if you define
only one HBA, the host can lose access if there is a problem. Click Next after defining
all the HBAs.
6. The next window requires you to specify the host type. This is basically the operating
system running on the host. It is vital that you select the appropriate host type because the
RDAC and ADT settings rely on this setting. In addition, this is the part of the configuration
where you configure the heterogeneous host support. Each operating system expects
slightly different settings and handles SCSI commands differently. If you make a wrong
choice, your operating system might not boot anymore or path failover cannot be used.
