1.1. Additional S/390 Hardware Preparation for Installation Notes

The network configuration must be determined beforehand. Red Hat Enterprise Linux for S/390 supports multiple network devices including CTC (channel-to-channel), IUCV (inter-user communication vehicle), LCS (LAN channel station), and QDIO-enabled (Queued Direct I/O) devices.

For the purposes of this installation, it is recommended that at least 4 GB of disk space (such as two 2 GB DASD, direct access storage device, partitions or equivalent zSeries SCSI LUNs) be allocated for the installation process. All DASD disk allocations should be completed prior to the install process. After the installation, more DASD or SCSI (for zSeries only) disk partitions may be added or deleted as necessary.
