| 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_tape_recovery is the Ignite-UX tool that is used to create the bootable system recovery tape. 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. The following bullet lists describe the components contained in the respective areas of the tape: Boot and Configruation Files: -
Boot files including ISL, HPUX, AUTO -
System configuration information such as hostname , IP address , disk layout , and so on. -
Ignite-UX kernel and user interface. Archive Information includes one of the following three: -
Minimum Core-OS to boot such as /sbin , /dev , /stand , /etc , /usr/bin , /usr/lib , /bin , /lib , /etc , and so on. -
Entire root volume group . -
Files from both root and non-root volume groups. You can easily include additional information to be placed in the archive as well as preview what processing will take place. The following is a summary of the make_tape_recovery command: /opt/ignite/bin/make_tape_recovery [ -s Ignite - UX_server ] [-a tape_drive ] [-A] [-b] [-B boot_destination_file ] [-d description ] [-f content_file ] [-i-ib] [-I] [-l lanic_id ] [-n num_cfg_dirs ] [-p] [-P s w e ] [-r] [-t tape_title_string] [-v] [-x content - options ] [XToolkit_Options] We'll use some of these options in our upcoming command line example. The following list shows the options you would use to add to or exclude from the archive: Adding to or excluding from an archive: -
-x include=< filedirectory > -
-x inc_cross=< filedirectory > (this can contain any number of include , exclude , inc_entire , and inc_cross options. -
-x exclude=< filedirectory > -
-x inc_entire=< vgname > /dev/dsk/ < name > -
-f < contents_file > -
-A (archive all volume groups that contain essential files) You include information in the archive with -x include and exclude with -x exclude except for essential files which can't be excluded. -x inc_cross includes a file or directory recursively and crosses mount points. -x inc_entire will include an entire volume or disk. Let's now run make_tape_recovery on a system. We'll issue three commands in the following example. The first is bdf , so that we can see the two volume groups on the system we wish to include: vg00 and vg01 . Next we'll run make_tape_recovery in preview mode with -p and include both volume groups. Lastly we'll resume making the tape with the -r option with verbose output specified with -v : [View full width] [View full width] # bdf Filesystem kbytes used avail %used Mounted on /dev/vg00/lvol3 204800 70942 125523 36% / /dev/vg00/lvol1 299157 26222 243019 10% /stand /dev/vg00/lvol8 2609152 140280 2315011 6% /var /dev/vg00/lvol7 1056768 767093 271616 74% /usr /dev/vg00/lvol5 204800 1368 190782 1% /tmp /dev/vg00/lvol6 1056768 691086 342888 67% /opt /dev/vg00/lvol4 512000 1234 478849 0% /home /dev/vg01/lvol1 4096000 2104 3838035 0% /backup # make_tape_recovery -x inc_entire=vg00 -x inc_entire=vg01 -p * Creating local directories for configuration files and archive. ======= 03/25/02 10:36:24 EST Started make_tape_recovery.

The LIF area is first written to the tape, then all of the information from the two volume groups is included. You can see that the make_sys_image script is called after the LIF area is written to the tape. Both volume groups were active at the time this tape archive was produced; however, there was minimal activity on the system.  |
