Thanks Jens

 

I'll get myself acquainted with the SMcli command :)

To be honest, I can't say for sure. If you're lucky all will go well. 

Usually you should clean the drives before moving. 

 

Do the drives from the other MDs represent complete RAID groups? Or just
parts of it? 

The 1st case will increase your chances. 

 

If a wipe beforehand isn't possible, here is what I would do: 

1.      Install all drives in MD1000

2.      Power off both systems 

3.      Connect MD1000 to MD3000 and power on 

4.      If HDDs are imported automatically just delete RAID groups +
volumes on it via MDSM

5.      If not, you will have to initialize every single HDD manually
using SMcli command 

 

One more thing to let you know. If you install HDDs in a running
MD3000(i) enclosure (or an attached MD1000) too quickly you might
experience a corrupt DACstore in rare cases. 

So if you ever install drives in a running system, do them one by one
with plenty of time in between. 

 

Good luck, 

Jens.

Hi

 

we have an MD3000 running fine. I am going to add an MD1000 to it. 

The only thing I'm uncertain about is the disks in the MD1000 are taken
from several now unused MD1000's that were originally attached to an
MD3000i, but the disks have not had the RAID config wiped.

 

Will the MD3000 be able to see the 'used' disks in the newly attached
MD1000 successfully and be OK with creating virtual disks out of them ? 

 

Many thanks,

Nick .
