To configure FCP devices you must configure
the IODF, define zones in the switch or fabric, control access to
the LUN with LUN masking, and configure the zfcp device driver. Under z/VM®, you might also need to
attach the FCP device.
Before you begin
- A FICON® or FICON Express
feature is available. See Supported hardware.
You must configure the hardware as an FCP channel within your IODF.
- The FCP channel is connected to a Fibre Channel
SAN through a switched fabric connection (unless a point-to-point
connection is used)
- The target device is connected to the same Fibre Channel SAN (or
through a point-to-point connection to the FCP channel).
Procedure
To access a Fibre Channel-attached SCSI device follow
these configuration steps:
- Configure an FCP channel in the IODF
of the mainframe.
- Configure zoning for the FCP channel to
gain access to desired target ports within a SAN. If the FCP channel is directly attached to a target device
(point-to-point connection), this step is not needed.
- Configure LUN masking for the FCP channel at
the target device to gain access to desired LUNs.
- In Linux, configure target ports
and LUNs of the SCSI device at the target port for use of zfcp.
What to do next
The configuration steps are explained in more detail in
the following sections.
