You must configure the z/VSE operating system
before you can use it with the
system.
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.
After the prerequisite tasks are complete, use the following
general steps to configure your host system that is running the z/VSE
operating system:
- 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 IBMz/VSE Administration publication
for additional information.
