Limitations; Preparation - HP Data Protector A.06.11 Recovery Manual

Limitations

• This description does not cover the recovery of a cluster environment. Depending
on the configuration of the cluster environment, additional steps and modification
to the environment are necessary.
• RAID is not supported.
• Auxiliary disk should be prepared on a system of the same hardware class as
the target system.

Preparation

Preparation for this disaster recovery method should be performed on several levels:
gathering the information for your backup specification, preparing the disk, preparing
your backup specification (pre-exec), and executing the backup. All of these
preparatory steps are necessary before executing disaster recovery of the client.
This section provides a list of items that need to be executed for each target system
at backup time, in order to perform successful disaster recovery. If the information is
collected as part of a pre-exec command, it is important to document the location of
these files in the Disaster Recovery plan so that the information can be found once
disaster strikes. Also version administration (there is a collection of the "auxiliary
information" per backup) has to be considered.
• If the system that will be backed up has application processes active at low run
levels, establish a state of minimal activity (modified init 1 run level) and enter
the single user mode to prevent errors after recovery (see
backup" on page 34). Consult your operating system documentation for details.
HP-UX:
Example
1. Move some kill links from /sbin/rc1.d to /sbin/rc0.d and complement
the changes for the boot-up section. The kill links include the basic services
that would otherwise be suspended by moving to run level 1, and they are
needed for the backup. For an example, see
1 1.x" on page 149.
