Hi,
I have a MSA 2040 running with dual controller. I can see that I have 10.9 TB space of which 7.9 TB has been provisioned, 1.1 TB free space(I believe spare HDD) and 1.8TB Reserved Space.(Refer attached image).
Well, my question now is whether can I use that reserved space to expand the existing volume?
I tried by right clicking the existing volume - tools - expand volume but I am getting only 1063 GB.
Is it taking from 1.1TB free space or from 1.8 TB reserved space?
Can someone explain about all those storage spaces?
PS RAID5 configured
Solved! Go to Solution.

Re: MSA 2040 Reserved space utilization
from manual:
Reserved space refers to space that is unavailable for host use. It consists of RAID parity and the metadata needed for internal management of data structures.
Hope this helps!
Regards
Torsten.

Re: MSA 2040 Reserved space utilization
Thanks Torsten.
Regarding my question "I tried by right clicking the existing volume - tools - expand volume but I am getting only 1063 GB."
So 1063 GB should be from the 1.1 TB Free space. But can I use this space for expansion?

Solutionyes you can expand the volume size as per the size it shows at the time expand operation. This space coming from free space available in vdisk which you can see at the down of the screenshot which shows 1063.1GB only.

Re: MSA 2040 Reserved space utilization
Hi
Now I have expanded the available disk space to a particular vdisk as in the picture(san.jpg) where it was intially 2 TB and after expanding its 3.1 TB which is mapped to a server but the server says its still 2 TB(as in server.jpg) and I am not able to see the expanded volume.
Do I have to do any additional configuration in order to replicate in the server?

Re: MSA 2040 Reserved space utilization
Try to stop production or application running on this MSA volume. Unpresent/unmap the volume from MSA and represent/remap the same
Hope this helps!

Re: MSA 2040 Reserved space utilization
After expanding it on MSA you must expand the Volume in Windows.
run diskmanager
Reload drives
This should show you free diskpace rigt of the provisioned Volume. Check wheter Volume ist BASIC or GPT. BASIC is limmted to 2 TB.
