ASR recovery process
For a complete description of the ASR Recovery process, see the documentation that accompanies your backup and recovery application.
The recovery process begins by booting the repaired or replacement system from the operating system CD, and then pressing F2 to begin the text-only mode of the ASR recovery process. This is followed by a prompt to insert the floppy disk that is created during the ASR backup process.
During the text-only mode you are prompted to insert the Storage Foundation CD as well as the CDs from your backup and recovery application and any other third-party applications that participate in the ASR recovery process. At the end of the text-only mode of recovery, the system performs an automatic restart. You may have to remove any floppy disks or CDs in order for the system to continue to the GUI mode of setup by booting through the hard disk.
The system restarts into GUI mode and the ASR Recovery process continues automatically. In the event of a failure, on-screen directions guide you.
Warning:
If there is a failure related to Volume Replicator during this phase, Veritas recommends that you retrieve and save all the error and trace logs when you are provided the opportunity to do so. You may not have access to these diagnostic files later as the system may not be in a bootable state if the error encountered is critical in nature. The error and trace logs can be found in the <systemroot>\repair folder.
After the successful completion of the GUI mode, you are again prompted to restart your system.
Following this final restart, your system is recovered and you are ready to begin the process of data recovery. The RVG configuration is restored, however, the Secondary is detached. You need to resynchronize the Secondary hosts. If any RVG was stopped, that is, the data access was disabled at the time of backup, then the RVG is started, that is, data access is enabled after restore.
