Hi Managers,
sorry for the longer delay in summarizing but I had a major diskcrash
on my home machine and lost several mails.
So if I do not mention someone - please excuse me.
My original question:
> I have an Sparc Storage Array with 30 Seagate ST32550W (each 2.1G and 5400 rpm).
> Two of the disks show errors.
> I have two newer ST32171WC (2.1G, 7200rpm) ready to insert for the SSA.
>
> The questions:

> Can I simply replace the two disks despite the fact that they are not
> truly identical?
>
> What performance issues may arise from the mix of 5400 and 7200 disks?
>
> And do I need a different entry for format.dat?
And this is from the answers:

We were using Veritas - I did not mention it because I was interested in
the possible hardware issues first. Sorry if I did not make it very clear!
From: Martin Oksnevad <martin@stavanger.geoquest.slb.com>
He poited out that my statement about the disks was wrong.
Both disk types mentioned are 7200rpm!
> The ST32550WC's are 7200 RPM Barracudas and so are the newer ST32171WC's.
>
> Just swap the bad disks with the new disks.
This is what we did.
Then we followed the Veritas instructions (we use RAID 0+1).
No real problems occured. The SSA is operating now with the new
disks for about three weeks.
So thanks for the help
