not likely.

That means you will be using option 7 (Stop RAID) and THAT means you
WILL have a full backup of your system before you attempt this
procedure. It is NOT an option.

Rob is right that you could use ASP balancing to drain the drive but why
not go into SST and simply remove the drive. This will completely drain
it AND remove it from the ASP. This can run while the system is still up.

After that you can do your backup, boot to SSD, End RAID, then start
that drive as a hot spare and then start RAID again.

That being said I wonder if you could minimize your downtime by removing
data from the disk, or at least as much as you can, beforehand.
