VxVM Disk Groups
The root-disk groups managed by VERITAS Volume Manager (VxVM) may be included in the Ignite-UX
archive since the B.3.8 release. However, prior to B.3.8 release,the VxVM disk groups cannot be included
in the Ignite-UX archive. If they are included,
make_net_recovery
will error. Those disk groups will
be left undisturbed and reintegrated into the system after the recovery is complete.
LVM Disk Mirrors Not Restored
The
make_net_recovery
tool will create a recovery backup for a system with mirrored disks but it
will not restore the mirrored disk configuration. If the system is later recovered, previously mirrored
volumes will no longer be mirrored. They may be manually remirrored after the system is up. Using the
config.local file in the clients directory, you may specify the LVM commands to restore mirrored
disks to be executed automatically after the system has been restored. For more details, see the
/opt/ignite/share/doc/diskmirror.pdf
white paper.
File System Volume Size May Be Modified
The file system volume size(s) in the recovery archive may be modified when the archive is installed. By
default, Ignite-UX will ensure 10% free space for each volume and modify the file system volume size
accordingly.
If you do not want Ignite-UX to modify the file system volume size(s) automatically, add:
init _hp_ignore_sw_impact=1
to the /var/opt/ignite/clients/0x
LLA/recovery/latest/system_cfg
file.
Warning: Setting _hp_ignite_sw_impact
to 1 may cause recoveries to fail if any file system sizes
are reduced below the minimum required.
Note that changes to the system_cfg file must be done after a preview has been created (-p). After making
the above changes, resume the creation of the tape recovery archive (-r).
File Names with Non-Printable Characters
Although permissible within HP-UX, it is inadvisable to use characters that do not have a printable
graphic on the hardware you commonly use, or that are likely to confuse your terminal. Filenames with
these characters cause a warning message to be displayed by
make_net_recovery.
In addition, files
that contain these non-printable characters are not included in the archive.
Running Commands in Single User Mode
HP recommends that the
make_tape_recovery
and make_net_recovery commands be run in
default mode of multi-user (run level 3 or 4 depending on how the system is configured). However, HP
does support execution of
make_tape_recovery
in single-user mode using the supported method
documented in Ignite-UX FAQs. (See Section 11, Network/Tape Recovery, Question 23.) A copy of the
Ignite-UX FAQs is installed with Ignite-UX in
/opt/ignite/share/doc/FAQ
, and the latest version
of the Ignite-UX FAQ may be obtained by sending an email to

.HP
does not recommend running
make_net_recovery
in single-user mode.
Non-Responding NFS Servers
The
make_tape_recovery and make_net_recovery
tools can handle non-responding auto-
mounted file systems accessed via indirect maps or the -hosts map without hanging. However, the tools
will hang if there are automounted file systems accessed via direct maps or directly mounted NFS file sys-
tems.
Unmounted File Systems in /etc/fstab file
If unmounted file system in
/etc/fstab is detected, a WARNING message will be displayed and the
make_tape_recovery and make_net_recovery
will complete with return code 2.
Data Recovery from Raw Logical Volumes
Only file system data is included in recovery archives created by
make_tape_recovery. Data
included in raw logical volumes (like those that contain database data) is not included in recovery
archives, and must be backed up as part of the overall backup stategy of a system.
LVM Volume Group Version 2.x or higher
Ignite-UX does not support the system recovery archive creation using the
make_net_recovery com-
mand for Volume Groups having Volume Group Version 2.0 or 2.1. If any LVM Volume Group having
unsupported Volume Group Versions is provided as arguments to make_net_recovery command, the
command fails and reports the unsupported volume groups. In such situations, either omit the
