| Ignite-UX is a product bundled with HP-UX 11i that provides a process to create a bootable system recovery tape. The tape contains a boot area and an operating system archive. Should your root disk fail or corruption of the root disk take place, you can recover using the bootable system recovery tape. make_recovery is the Ignite-UX tool that is used to create the bootable system recovery tape. make_recovery is being replaced by make_net_recovery at the time of this writing but make_recovery will be used throughout this section because the check_recovery function covered in this section was not yet implemented with make_net_recovery. You could boot and restore from the system recovery tape and then use your system backup to fully restore the system. If your root disk were to fail, in a non-mirrored environment, you would perform the following steps to recover from the failure: Replace the defective root disk. Boot from the recovery tape by selecting the tape device. Monitor the restoration of the operating system archive from the recovery tape. Restore the balance of data on the system with backup information.
The bootable system recovery tape consists of both a Logical Interchange Format (LIF) volume as well as the operating system archive. The LIF volume contains all the components necessary to boot from the tape. The operating system archive contains only the core operating system by default. You can include additional files in the operating system archive, if you wish, using two different techniques. The first is to edit the file /var/opt/ ignite/recovery/makrec.append and add to it the file name, directory name, or software distributor product name you wish to include in the operating system archive. The second technique is to run make_recovery in preview mode with the -p option, manually add files to include and/or exclude from the archive, and resume make_recovery with the -r option. The manual pages for /opt/ignite/bin/make_recovery and /opt/ignite/bin/ignite are online on your HP-UX system. You can also determine whether your recovery tape is up-to-date by using the check_recovery command. Running make_recovery with the -C option produces a system recovery status file. check_recovery compares the system recovery status file to the current state of the system and produces a list of discrepancies. From this list you can determine whether or not you should produce another system recovery tape. The manual page for /opt/ ignite/bin/check_recovery is online on your HP-UX system. The recovery feature is only one component of the Ignite-UX product. Ignite-UX provides a means to install systems over the network by either pushing the installation to a client from an Ignite server or pulling the installation from the Ignite server to the client. With Ignite-UX, "golden images" of your standard installation setup can be created and systems can be set up in a matter of minutes by "igniting" them from this image over the network. More information about Ignite-UX can be viewed on the Internet at http://www.software.hp.com/products/IUX and read about in the "Configuring an Ignite-UX Server" and "Installing from the Ignite-UX Server" chapters as well as Appendix C: "Ignite-UX System Administration" of the Installing HP-UX 11.0 and Upgrading 10.x to 11.0 manual from Hewlett-Packard. The "HP-UX System Recovery" chapter of the same manual gives additional information about the make_recovery feature of Ignite-UX. An Example of Creating a Bootable System Recovery Tape Now that we have covered the basic components and capabilities of the Ignite-UX recovery process, let's look at an example of creating a bootable system recovery tape. Let's first run make_recovery with the -p option so that we can see the way Ignite-UX reports the information it is including on the tape. I'll also use the -A option, which specifies that the entire root volume group is to be included. I sometimes use make_recovery to clone identical systems by producing a recovery tape with the -A option and then loading the tape on systems that I want to be identical to the original system. You would not use the -A option if you have a large root volume group or if you perform normal backups and don't need to include all root volume group information on the recovery tape. In addition to -p for preview and -A for all, I'll also use the -v for the verbose option and -C to create the system status file in the following preview command example: # make_recovery -p -v -A -C *** Previewing only *** Option -A specified. Entire Core Volume Group/disk will be backed up. *************************************** HP-UX System Recovery Validating append file Done File Systems on Core OS Disks/Volume Groups: vg name = vg00 pv_name = /dev/dsk/c0t5d0 vg00 /dev/vg00/lvol3 / vg00 /dev/vg00/lvol4 /home vg00 /dev/vg00/lvol5 /opt vg00 /dev/vg00/lvol1 /stand vg00 /dev/vg00/lvol6 /tmp vg00 /dev/vg00/lvol7 /usr vg00 /dev/vg00/lvol8 /var Create mount points /apps /work /spill /spill2 /rbdisk01 /rbdisk02 /rbdisk03 /rbdisk04 /rbdisk05 /rbdisk06 /rbdisk07 /rbdisk09 /rbdisk10 /rbdisk11 /rbdisk12 /rbdisk13 /rbdisk14 /rbdisk15 /rbdisk16 /rbdisk17 /rbdisk18 /nfs /opt is a mounted directory It is in the Core Volume Group Mounted at /dev/vg00/lvol5 /var is a mounted directory It is in the Core Volume Group Mounted at /dev/vg00/lvol8 Destination = /dev/rmt/0m Boot LIF location = /var/tmp/uxinstlf.recovery *************************************** Preview only. Tape not created The /var/opt/ignite/recovery/arch.include file has been created. This can be modified to exclude known files. Only delete files or directories that are strictly user created.
