RE: Disks economical for P720?

I did that once on a 270-2248 we used for development. 2 raid sets. Had to save off a lot of test data to squeeze everything into one set and then swap, lather, rinse, repeat, restore.


As you said, ugly & slow (that little 270 was a tortoise) but it worked.


And, when I was done, I took the old drives and added them to the production 720 (an OLD 720 - we're talking small refrigerator) in an new-to-me drive cage. It was a "two-fer" upgrade.

We did the same back on a P5, 35 and 70 to all 141.
I didn't do a unload/reload, but migrated data from 1 raid set to another, then replaced the empty raid set with higher capacity drives, the migrate the data to the new drives, repeat the process.
It was ugly, slow, but got the job done without a reload.

What size disks are you using now? We were tight on slots back when we had a P6. We did an unload/reload to higher capacity drives.

We don't have any slots free. The off-the-cuff response we got from our
BP was that we'd have to add a SAN to our P720, and that would be VERY
expensive. I reluctantly accepted that answer, until I found myself in
the office afterhours, yet again, to babysit my single Windows server.

The disks are 500 for 141GB, and about 1000 for 283GB. Pretty inexpensive
if you have the slots.

You can get these even cheaper on the used market.
