红帽全球峰会第 9 章 Preparing a RHEL installation on 64-bit IBM Z
You can install Red Hat Enterprise Linux on the 64-bit IBM Z architecture.
9.1. Planning for installation on 64-bit IBM Z
Red Hat Enterprise Linux 10 runs on IBM z14 or IBM LinuxONE II systems, or later.
The installation process assumes that you are familiar with the 64-bit IBM Z and can set up logical partitions (LPARs) and z/VM guest virtual machines. For installation of Red Hat Enterprise Linux on 64-bit IBM Z, Red Hat supports Direct Access Storage Device (DASD), SCSI disk devices attached over Fiber Channel Protocol (FCP), and virtio-blk and virtio-scsi devices. When using FCP devices, use them in multipath configuration for better reliability.
DASDs are disks that allow a maximum of three partitions per device. For example, dasda can have partitions dasda1, dasda2, and dasda3.
- Pre-installation decisions
- Whether the operating system is to be run on an LPAR, KVM, or as a z/VM guest operating system.
Network configuration. Red Hat Enterprise Linux 10 for 64-bit IBM Z supports the following network devices:
- Real and virtual Open Systems Adapter (OSA)
- Real and virtual HiperSockets
-
virtio-netdevices - RDMA over Converged Ethernet (RoCE)
-
Ensure you select machine type as
ESAfor your z/VM VMs, because selecting any other machine types might prevent RHEL from installing. See the IBM documentation.
When initializing swap space on a Fixed Block Architecture (FBA) DASD by using the SWAPGEN utility, the FBAPART option must be used.
