You must configure the z/VSE® operating system
before you can use it with the system.
Before you begin
Before you configure the z/VSE operating system, the
following tasks must be completed:
- A service representative must install the system.
- You must install the appropriate host bus adapter (HBA) for your z Systems® server.
- You must configure the FICON®
Express adapter or HBA in FCP mode. FCP mode means that
the HBA is configured with channel path ID (CHPID) type FCP in the input/output control data set
(IOCDS) of your z Systems server.
About this task
After the prerequisite tasks are complete, use the following general steps to configure
your host system that is running the z/VSE operating
system:
Procedure
-
Zone the host to the system on the Fibre Channel SAN.
For more information, see the zoning details and zoning examples topics in the Configuring
section in this product information.
-
Create the host on the system by using the worldwide port names (WWPNs) of your FCP adapter.
Map the volumes to the host, as required.
Note: With N_Port ID Virtualization (NPIV), multiple virtual FCP adapters can be defined. Each
virtual FCP adapter can have its own unique WWPN. You can use the WWPN of a virtual FCP adapter to
map volumes to the host. This action can be used to define multiple hosts that share the same
physical FCP adapter. The NPIV support was introduced with System z9®.
-
Configure your z/VSE system to use FCP-attached SCSI
disks. After you configure a path to the SCSI disk, the SCSI disks are recognized by z/VSE user programs and system programs as fixed block
architecture (FBA) disks only. You can use the SCSI disks with existing FBA interfaces. The z/VSE operating system does not provide SCSI command support for
applications. See the IBM
z/VSE Administration publication for additional
information.
