You require hardware that supports the SCSI
IPL feature.
To be able to IPL a Linux system
from a SCSI disk, the following hardware is required:
- The SCSI IPL hardware feature.
- As of z10™ machines,
SCSI IPL is a base function.
- On z9® machines, you require
the no-charge feature FC 9904.
- On z990 and older machines, you need to order and install SCSI
IPL separately using Feature Code FC 9904. Models z800 and z900 require
an initial, one-time power-on-reset (POR) of
the machine to activate the feature. Activating the SCSI IPL feature
is concurrent on z890, z990, or newer, machines.
- An FCP channel. See Supported hardware.
You must configure the hardware as an FCP channel within your IODF.
- One or more FCP-attached SCSI disks from which to IPL.
Also see your Linux distribution
for further prerequisites.
