I would add one point to the suggestions offered so far.  Restoring to a
model 12H AutoRaid array can be a painfully slow operation.  Put your array
in "High Performance" mode during the restore, and its performance should be
reasonable.  The array is slightly more vulnerable to data loss while in
this mode, so be sure to return it to standard mode after the restore.

Subject: Conversion to Raid Array?


On a 928RX we are going to convert from standard SCSI disc drives to an
AutoRAID array (12H).

Problem is this is a 24/7 system. Every moment of downtime is very costly.

Does anyone have any suggestions as to how to reduce the downtime from the
several hours that would be required for a full back-up to tape followed by
a full restore to the raid array?

Is it possible to copy the current 7 individual drives directly to the
AutoRAID array without the intermediary of tape?

Any other suggestions, gotchya's etc.?

Thanks in advance.
