You must configure the z/VSE™ operating
system before you can use it with the SAN Volume Controller.
Before you configure the z/VSE operating
system, the following tasks must be completed:
- An IBM® service
representative must have installed the SAN Volume Controller.
- You must have installed the appropriate host bus adapter (HBA)
for your System z® server.
- You must have configured the HBA in FCP mode. FCP mode means the
HBA has been configured with channel path ID (CHPID) type FCP in the
input/output control data set (IOCDS) of your System z 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 system to the SAN Volume Controller on
the fibre-channel SAN. See the IBM System Storage® SAN Volume Controller
Software Installation and Configuration Guide for
additional information about zoning.
- Create the host system on the SAN Volume Controller,
using the worldwide port names (WWPNs) of your FCP adapter. Map the
VDisks to the host, as required. See the IBM System Storage SAN Volume Controller
Software Installation and Configuration Guide or IBM System Storage SAN Volume
Controller Command-Line Interface User's Guide for
additional information about creating hosts and mapping.
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 VDisks to the
host. This action allows you 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 (SC33-8304)
manual for additional information.
