Hi,
I have two MSA 2000 with 5 disks each. There is a RAID10 running on it (1 spare disk). It have three volumes and the volumes are available on the linux host.
I need to get more disk space and I decided to put in four additional disks. I configured them on the MSA as another RAID10 by the web interface and put one volume on it. After I restarted the Storage and Management Controller of the MSAs I rebooted the Linux host. I would have expected that the new volume shows up as sd[gh] device in the dmesg but it does not.
Any ideas what I missed ?
Many thanks in advance.

Re: Extending an MSA20000 by another RAID10 does not show volumes on linux host.
Hi Cali,
thank you for the hint. That was the solution.
Many thanks.
