Off-host FlashSnap procedure (Two servers)
The following is the off-host FlashSnap procedure.
To use the off-host FlashSnap procedures with two servers
- Use the Prepare command to attach a snapshot mirror to a volume on the working server.
You need to perform this step only once for the initial setup.
The Prepare command replaces the Snap Start command in the GUI. Both prepare and start keywords are available in the CLI, however prepare is the recommended keyword.
- Use the Snap Shot command to automatically detach the snapshot mirror and create a new volume that is associated with the snapshot mirror.
This new volume can be used for backup or other purposes. The snapshot process typically takes less than 20 seconds.
- Split the new volume from its dynamic disk group with the Split Dynamic Disk Group command, creating a new dynamic disk group on the server.
- Deport the new dynamic disk group from the original server.
When you use the command line, a separate deport command is not necessary. It is needed only for the VEA GUI command.
- Rescan on the second server so that the computer recognizes the split-off dynamic disk group.
- Import the dynamic disk group on the second server where the backup or other off-host processing occurs.
- Perform the backup or other off-host processing activity, using the snapshot volume.
To backup the server, NetBackup or Backup Exec is recommended for the backup software.
- Deport the dynamic disk group from the second server.
If you do not have a SAN where you can access the deported dynamic disk group from the original server, physically move the split-off disk group's disks back to the original server.
- Rescan on the original server, so that the server recognizes the split-off dynamic disk group.
You do not need to import the dynamic disk group back to the original server.
- Use the Join Dynamic Disk Group command to join the split-off dynamic disk group back to its original dynamic disk group.
- Join the mirrored volume back to its original volume, using the Snap Back command.
The mirrored volume is now resynched to the data source and is continually updated. Because FastResync (FR) is used in resynchronizing the mirrors, the time for the resynchronization is greatly reduced.
The next time the sequence of commands is run again, the snapshot mirror is ready for the snapshot step. The Prepare step, step 1, does not have to be done again.
