Summary The Insight Control (IC) server provisioning appliance comes pre-packaged with OS Build Plans (OSBPs) that perform scripted installations of Red Hat Linux and SUSE Linux. Currently, it does not have OSBPs that allow the capture of Linux system images and the deployment of those images back to target servers. This technical paper will provide instructions to create OSBPs to capture and deploy Linux images.

Mount Server Image Script Create a new script that creates a target directory (/mnt/target) and then mounts the target server’s image to /mnt/target. The example script below uses a standard RH6.3 installation with only two mount points. If the server’s /etc/fstab indicates more than just /boot and /root as mount points, then the script will need to be modified to reflect the mount points of the image to be captured. IMPORTANT: Do not mount a swap partition.

Environment as well, but that would require additional modifications to some of these scripts to ensure that the VID doesn’t get modified or included in the image capture. c. Keep the third step, Wait for HP SA Agent. d. Add the Set Media Source script to mount the Media Server on /mnt/images. Include the following parameters in the script step: @__OPSW-Media-WinUser@@__OPSW-Media-WinPassword@@__OPSW-MediaWinPath@#/mnt/images?noserverino e.

Intelligent Provisioning Environment and the PXE booted LinuxPE will automatically attempt to mount the server’s image. To create a new script to unmount the disk partitions: 1. On the IC server provisioning appliance, create a new script of Unix type and name it for the appropriate function. 2. Create the script content or copy and paste the script content from an external application.

3. Click OK to save the script. Create New Filesystem Script Create a new script that repartitions the disk, creates logical volumes/groups and creates the filesystem to receive the new image. While the sample script partitions the disk so it replicates the old partition table, it is possible to alter the new partition if required. Any new changes will have to be reflected in the target server image’s /etc/fstab once the image has been deployed. To create a new script to create the filesystem: 1.

2. Create the script content or copy and paste the script content from an external application. For example, the script would contain: #!/bin/bash #Now mount new setup. mkdir -p /mnt/target mount /dev/mapper/VolGroup-lv_root /mnt/target #mkdir –p /mnt/target/home #mount /dev/mapper/VolGroup-lv_home /mnt/target/home mkdir -p /mnt/target/boot mount /dev/sda1 /mnt/target/boot 3. Click OK to save the script. Deploy Linux Image Script Create a new script that deploys the previously captured Linux image.
PAGE 9
sed -i -e '/^HWADDR/d' -e '/^UUID/d' /mnt/target/etc/sysconfig/network-scripts/ifcfg-eth0 rm -f /mnt/target/etc/udev/rules.d/70-persistent-net.rules # # Hostname exit 0 3. Click OK to save the script. Re-Install HP SA Agent Script Create a new script that sets up the target server to re-install the HP SA Agent after the server has rebooted for the first time into production. It is a fairly complicated script and requires that it be passed the IP address of the appliance.

uname -a | grep 86_64 if [ $? -eq 1 ] ; then echo "Cannot migrate x86 target" >> $logfile exit "11" fi if [ -e /etc/redhat-release ] ; then cat /etc/redhat-release | grep "6.*" if [ $? -eq 0 ] ; then echo "found RHEL6" >> $logfile filename="opsware-agent-LINUX-6SERVER-X86_64" fi cat /etc/redhat-release | grep "5.

a. Keep the first step, Check iLO Service. b. Modify the Boot step to ensure that the PXE LinuxPE service OS is booted by adding --method network parameter to the Parameters field. It is possible to avoid using this parameter and use the Intelligent Provisioning environment as well, but that would require modifications to some of the scripts to deal with the VID. c. Keep the third step, Wait for HP SA Agent. d. Add the Set Media Source script to mount the Media Server on /mnt/images.
PAGE 12
IMPORTANT: Do not mount a swap partition. Reviewing the target server’s /etc/fstab file will provide information on what partitions are swap. NOTE: HP Smart Array Controllers are listed as device /dev/cciss/cXdXpX under SLES 11 SP3. However when the same machine is booted into ICsp Linux preboot environment, they get discovered as /dev/sdX (X indicates whether it is first device or second device etc.).

d. Add the Set Media Source script to mount the Media Server on /mnt/images. Include the following parameters in the script step: @__OPSW-Media-WinUser@@__OPSW-Media-WinPassword@@__OPSW-MediaWinPath@#/mnt/images?noserverino e. Add the new Mount Server Image script as created in the Mount Server Image Script section. No parameters are required. f. Add the new Capture Server Image script as created in the Capture Server Image Script section.

1. On the IC server provisioning appliance, create a new script of Unix type and name it for the appropriate function. 2. Create the script content or copy and paste the script content from an external application. For example, the script for simple partitioning of SLES 11 SP3 would contain: #!/bin/bash ## Assumes first disk /dev/sda to be used. Change if needed disk="/dev/sda" # Partition disk echo "Partitioning disk...

2. Create the script content or copy and paste the script content from an external application. For example, the script would contain: #!/bin/bash tar jxf /mnt/images/LinuxImages/$1.tar.bz2 -C /mnt/target where the image name will be passed in as a parameter to the script step and the Media Server is mounted on /mnt/images. 3. Click OK to save the script.
