Using make_tape_recovery
The creation of make_tape_recovery tapes is supported on vPars-enabled servers using vPars A.02.03 or
later. However, recoveries using these tapes must be done outside of the vPars environment; they cannot be
used to recover a system from within a virtual partition. For example, the tape cannot be used with the
vparboot -I command.
Assumptions
In the following example, it is assumed that the version of vPars in the tape archive is the same as that
installed in the other virtual partitions.
If the virtual partition being recovered owns the system or hard partition's primary boot path, and if changes
have been made to the vPars configuration since make_tape_recovery was run, then the recovered vPars
database (/stand/vpdb) will be out of date.
If the recovered configuration is out of date, the recovery will require one of the following additional steps:
• Boot the vPars Monitor from an alternate boot disk with the current vPars database. When the recovered
virtual partition is booted, the database will be synchronized with the current configuration.
• Recover an up-to-date database file from a backup before booting the vPars Monitor.
• Boot the vPars Monitor and the recovered partition, and then update the configuration with vparmodify,
vparcreate, and vparremove.
Archiving the Virtual Partition(s)
This section describes how to create the recovery tape.
NOTE
• To recover a single virtual partition from a tape, all active virtual partitions must be
shutdown.
•The make_tape_recovery command is not a backup utility. The virtual partition should be
backed up separately. A well thought out backup strategy should be part of every recovery
plan. Your normal backups may be required to recover the virtual partition. Test your
recovery plan to make sure it works properly
1. The virtual partition must have a tape drive attached, as it will be used in step 4 to boot the tape. The
tape drive must be available to the nPartition at boot time.
# make_tape_recovery -A -a /dev/rmt/1mn
The following is archived to tape when make_tape_recovery is run:
a. The data necessary to recover the virtual partition on a “cold” system (nothing running on it,
including vPars). This includes the system filesystems (root, /stand, etc.)
b. The files required by vPars: the vPars Monitor (the default is /stand/vpmon) and the vPars database
(the default is /stand/vpdb).
2. You must document the following information about the system (not the virtual partition) and must be
available in hard copy or electronically in an accessible location not on the system itself.
a. The primary and alternate boot paths. You must get this information from the boot console handler
(BCH). You cannot retrieve this information via the setboot command from a virtual partition.
