Re: Changing a RAID configuration - Adding/removing disks -- MIDRANGE-L

Pete,

The new drivers are 70GB vs the original ones at 35GB. (But you knewthat!) You should be able to start parity on those drives even now withthe data on them. They can be in the same ASP, that's not a problem theywill just be a different RAID set.

Boot the thing to DST to into Work with Disk Units, then tell it toStart Disk Parity. If it doesn't let you do that with the data stillthere then you'll need to remove the new drives from the ASP, then startParity, then add them back into ASP 1.

I have a customer with a new i5 520 that we added 4 drives to. Itoriginally had 4 drives and we added 4 more. The problem is that Iadded the new units to the existing ASP (1) and it turns out the newdrives were a different size and model than the original 4 so theycouldn't be added to the RAID parity set. I need to correct this beforewe go into production.
So, what I'd like to do is get these new drives as part of a protectedraid set. Current disk protection status is:

The storage controller displays asa 573D when I use Work with Storage Resources. Or, is there a betterway to do this? Also, I have typically worked with smaller system thathave only one ASP, is there a downside to multiple ASP's?
If I do remove the 4327's from ASP 1 and create a new ASP, how do I movedata off of them?
Just need a few pointers on how to proceed.
