How To
Summary
A step-by-step example procedure for creating a bootable image for the Recovery media to install or upgrade a 7042-CR9 to V9R2M950
Objective
The V9R2M950 image is larger than previous images and won't fit on a regular DVD requiring additional steps in order to create alternatively USB media to boot from. This document is an example of a method to create the image and is provided as a guide.
Environment
7042-CR9 scratch install of V9R2M950
7042-CR9 updated to the minimum required for V9R2M950 upgrade
Pre-requisites:
Version 9 Release 1 M942 (Service Pack 2 MH01876) + Mandatory PTF MH01857 Save upgrade fix for HMC V9R1 M910+
User must run Save Upgrade Data after installing mandatory fix and before upgrading. Refer to Upgrading HMC code to V9R2M950 returns a pre-requisite iFix required for upgrade is missing.
Steps
Pre-requisites require the syslinux-utils and util-linux packages to perform the following steps:
- Download the HMC_Recovery_V9R2M950_CR9.iso image from fixcentral or the IBM ftp site.
-
Run isohybrid on the ISO image.
isohybrid HMC_Recovery_V9R2M950_CR9.iso
Expected messages "isohybrid: Warning: more than 1024 cylinders: 4778 isohybrid: Not all BIOSes will be able to boot this device". -
Create a bootable USB as follows:
- Identify the USB device name with "lsblk".
If necessary, compare the output before inserting the drive, and after.
Example: /dev/sdb- Erase the drive with wipefs (NOTE: All data in the drive will be lost! Ensure the correct drive was identified)
wipefs --all /dev/sdXExample for /dev/sdb:
wipefs --all /dev/sdb- Run the parted utility against the USB device:
parted /dev/sdX
Example (for /dev/sdb):
# parted /dev/sdb
GNU Parted 3.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted)- Set the label to msdos from the parted prompt:
(parted) mklabel msdos- Call the mkpart command from the parted prompt:
(parted) mkpart- When prompted for partition type, enter primary
Partition type? primary/extended? primary- When prompted for filesystem type, enter fat32
File system type? [ext2]? fat32- When prompted for a Start, enter 0%
Start? 0%- When prompted for an end, enter -1s
End? -1s- Enter quit to end parted
(parted) quit -
Change directory to the location of the iso image.
-
Write the image to the drive with the dd command (this process takes several minutes):
dd bs=4M if=HMC_Recovery_V9R2M950_CR9.iso of=/dev/sdX status=progress && syncExample (for /dev/sdb):
dd bs=4M if=HMC_Recovery_V9R2M950_CR9.iso of=/dev/sdb status=progress && sync
4924112896 bytes (4.9 GB) copied, 32.400682 s, 152 MB/s
1194+1 records in
1194+1 records out
5010096128 bytes (5.0 GB) copied, 480.332 s, 10.4 MB/s
NOTE: Do not try to write to sdb1 or sdc1, follow the example. -
The USB media is now ready.
-
Insert the USB in the 7042-CR9 and reboot.
-
When the BIOS Splash screen appears select F12 to select boot device USB Storage.
-
The HMC reads the media and displays the Hardware Management Console Install Wizard window. Select the desired option "Upgrade to a new version" or "Install".
10.Continue with the install or upgrade.
