Installing Redhat and SuSE on a power server using a USB flash drive

PowerLinux installation is almost as convenient as x86 Linux installation. But there may be a bit of trouble in some cases, for example, a power server that does not have VIOS installed, does not have a built-in optical drive, and does not find a compatible USB external drive, and how do we install it in addition to the cumbersome network installation.

Here, describe how to use USB Flash disk to start installation powerlinux.

First, we need to have a larger USB flash drive, at least 4GB, capable of loading a powerlinux DVD image file. In view of possible compatibility issues, it is recommended that you use the USB flash drive that you have on your IBM server or storage device, or you may not be able to find a USB flash drive such as a Scandisk or other large brand.

In addition, we need a Linux environment that is connected to the installation target network, both power Linux and x86 Linux are available. If you are always experiencing a USB flash drive to install PowerLinux, you can install a Linux environment in your own notebook. This Linux environment has two functions, first, to make Linux boot USB flash disk, and second, as the installation source. Here I used a x86 Redhat 6.2 environment.

Of course, we also need to install the PowerLinux ISO file (DVD ROM also can).

Next, I will detail the installation process of the USB flash disk on the power server for RedHat and SUSE respectively.

Installing RedHat for power with USB Flash disk

First, we introduce the installation process of RedHat for power, which is tested on RedHat 6.2 for power.

Ready to start USB flash drive

Copy the ISO file of RedHat 6.2 to the Linux environment.

First find the USB device.

# Lsusbbus 001 Device 001:id 1d6b:0002 linux Foundation 2.0 root hubbus 002 Device 001:id 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001:id 1d6b:0001 Linux Foundation 1.1 root hubbus 001 Device 002:id Smart 0e39:1014 Modular Www.aliyun.com/zixun/aggregation/3447.html ">technologies, Inc.

Use the DMESG command to determine the device name used by USB:

# Dmesg......usb-storage:device Scan COMPLETESCSI 2:0:0:0: direct-access Smart Smart USB 8GB 880C pq:0 ansi:2 ccssd 2:0:0:0: [SDI] 15728640 512-byte logical blocks: (8.05 gb/7.50-GiB) SD 2:0:0:0: [SDI] Write Protect is OFFSD 2:0:0:0: [SDI] Mode sense:43 00SD 2:0:0:0: [SDI] assuming drive cache:write THROUGHSD 2:0:0:0: [SDI] assuming drive cache:write through 2:0:0:0: [SDI] assuming drive cache:write THROUGHSD 2:0:0:0: [SDI] checkmark SCSI removable disk

In my environment, the device name for the USB Flash drive is SDI.

Use the DD command to make the splash drive.

# dd If=redhat62.iso OF=/DEV/SDI bs=32m

When the command is complete, start the flash drive and do it.
