MSA20 RAID 5 two identical drives

[Uwe Zessin]

On second thought, you might also want to run two variants as well, like:

wmic diskdrive get * /format:csv > diskdrive.csv
wmic diskdrive get * /format:htable > diskdrive.html

Uwe, I executed all the commands. On the Shadowcopy and Shadowstorage I got "no instance available", so these files are empty. I've included them all in the attached zip-file. I hope this will do and am looking forward to you reply!

Vielen dank bis jetzt!

'no instance available' means that no shadow copies are active.


Now, to me it looks like the Windows volume manager (this is a dynamic disk!) has become confused. On the other hand, i seems like you have made some configuration since you created this thread.

The original driver letter was X:, not R: and the size of the disk was 1.4TB, not 2TB, right?

Very confusing and I don't have an idea what is causing this, sorry. :-(

Yes that's right, we made some adjustments. We started all over again and this time we created an array without a spare so that explains the 2Gb instead of 1.4Gb. We also named the drive R instead of X to see if anything would happen with the drive I. Nevertheless we still have the same problem of two drive letters using the same logical drive (the one with 2Gb storage). I tried to make it all visible in my last screenshot.
To bad you cant figure out whats wrong but I want to thank you very much for all your efforts and time spend on this thread! Hopefully I will wake up some day with a brilliant idea ...

Sorry .... in my previous reply I meant 1.4Tb and 2Tb .... not Gb.
