Gary is right, if you have enough diskspace, migration is not needed, you
can also use move data or move nodedata to migrate the data.
But if you use the first stgpool on disk, just to migrate all data to tape,
diskpool is much easier, faster and as you noticed cheaper than a filepool.
A diskpool
Hello,
We replaced a primary disk pool on fc disks with a bigger primary
sequential pool on sata disks.
The primary sequential pool on disk is migrated to a primary pool an tape
using 3 processes.
Both pools are collocated by node.
Now we need more tapes in the next pool because the migration
Give the move data command a try.
This will move data from one volume in a sequencial pool to another.

What is the tape drive model? Data transfer rate of LTO4 drives is about
120MB/s, so three drives can carry 3 x 120 = 360 MB/s. (This can be higher
with LTO5 or new IBM tape drives). I don't know your SATA disk
configuration, but you might not gain performance by three parallel
