Re: AW: DASD problems

Doesn't sound like a bad idea. Just remember the system decides how to mirror based on where drives are ie BUS level, IOP/CTLR Level and finally Device Level. You might have to build your disk cfg 2 drives at a time to get the results you want.

Hello,

as we don't see a short-term solution to the disk problem, one of my
colleagues just came up with an interesting 
idea:

We had 20 drives with a serial number of 33-xxx. 6 drives have been replaced
with 68-/75-xxx serial numbers.
Those new drives have had no problems (yet).

Now how about creating a mirror configuration with a new 68-xx drive and an
old 33-xxx for each mirror pair? 
Assuming that the new drives are okay, this would decrease the chance of a
faulty mirror pair.

We would only need 4 new drives, and I guess, we could do it online.

'What do you think,

Best Regards,

Oliver Wenzel
