Recovery Solution Map
This document is comprised of sections describing specific recovery topics
and procedures. Table 2-1 shows how each failure type potentially affects the
various DPM components, and which section in this document is applicable
to the specific failure type.
As you explore different failure/recovery scenarios, keep the following
guidelines in mind:
• Re-installation of the operating system usually requires you to reinstall all
of the applications on your system.
• A non-recoverable failure of the RAID group containing the operating
system will require reinstallation of the operating system and all
applications
• A non-recoverable failure of the RAID group containing one or more DPM
replicas requires restoration of the replicas on that RAID group from tape,
or a secondary DPM server.
