IBM System Storage DS3000: Introduction and Implementation Guide
Zone2: x3755_P1_CtrlB, with members
– second HBA port (alias x3755_QL_P1)
– DS3400 controller B (alias DS3400_CB_P0)
This zone links second HBA port with controller B and thus represents the alternative I/O
path.
3. We create a configuration based on the zones. Actually, we will create two configurations:
– x3755_CtrlA_only
This configuration contains zone x3755_P0_CtrlA only. This means only the primary
I/O path between the first HBA and controller A is enabled. The initial SAN boot
installation steps require that the host server and the DS3400 only use one I/O path -
this will therefore be the configuration used in this part of the process.
– x3755_bothCtlr
We will use this configuration to enable both I/O paths. Therefore, both zones
(x3755_P0_CtrlA and x3755_P1_CtrlB) will be members. We will enable this
configuration after the Linux RDAC is installed.
Figure 21-7 shows our zoning. As stated above, the effective configuration must be
x3755_CtrlA_only at this time.

21.4 Create a logical drive
We will use the DS3000 Storage Manager running on a management workstation to create a
logical drive that will be used to install and later boot Linux. But before creating the logical
drive, we have to define our host server and its host port (first HBA port).
