In the following examples you can substitute a hot-swappable
disk for the SAN LUN. Refer to your Storage Area Network software
documentation for information on presenting and unpresenting a LUN
to a system. Example 6-1 Provisioning a New System In this example, you have a blade named SALES01 that is running all the correct releases of the correct OE software,
and you have another blade (not yet running anything) that you want
to set up as SALES02 (a hostname not yet
in use), with the identical OE software as SALES01. You would perform the following steps: Clone the SALES01 system
to a SAN LUN. Create a system information file with SYSINFO_HOSTNAME=SALES02, and the SYSINFO_MAC_ADDRESS, SYSINFO_IP_ADDRESS, and SYSINFO_SUBNET_MASK for SALES02. Execute the drd rehost command,
specifying the system information file created in the previous step. Create a Virtual Connect Profile for the second blade, SALES02. Unpresent the LUN from the first blade, SALES01, and present it to the second blade, SALES02. Choose the new LUN from the boot screens and boot
the SALES02 blade.
In this example, no system with hostname SALES02 existed before you booted the new blade. You must specify
a unique hostname for the rehosted clone. Example 6-2 Updating a System to an Existing System's Maintenance Level In the next example, you use cloning to bring a system up to
the same maintenance level as another system. Support system DEVEL01 is running an HP-UX 11i v3 0803 maintenance
level, and DEVEL02 is running an HP-UX 11i
v3 0709 maintenance level. Rather than use drd runcmd to install 0803 on DEVEL02, you want to
clone DEVEL01 and boot the clone on DEVEL02 (with hostname DEVEL02). You would perform the following steps: Clone DEVEL01 to a SAN LUN. Create a system information file with SYSINFO_HOSTNAME=DEVEL02, and the SYSINFO_MAC_ADDRESS, SYSINFO_IP_ADDRESS, and SYSINFO_SUBNET_MASK for SALES02. Execute the drd rehost command
to copy the DEVEL02 system information file
to the cloned disk. The system information file has SYSINFO_HOSTNAME=DEVEL02 and the correct SYSINFO_MAC_ADDRESS, SYSINFO_IP_ADDRESS, and SYSINFO_SUBNET_MASK for DEVEL02. Unpresent the SAN LUN from DEVEL01 and present it to DEVEL02 Use setboot to make the cloned
disk on DEVEL02 the boot disk and then reboot DEVEL02; or you can simply reboot DEVEL02 and interrupt the boot to set the new LUN as the boot disk in the
EFI interface.
In this example, DEVEL02 is a pre-existing
hostname, but you are booting the same system, just using a different
boot disk. |
