SolutionHello,
To add a new disk-group follow the instructions in the SMU Guide: https://support.hpe.com/hpesc/public/docDisplay?docId=a00017707en_us
You can begin at page 80 for Virtual Disk Groups. During the creation of the disk-group you will be allowed the option to select Pool A or Pool B - this will depend on which volume you want to increase in size or which Pool you wish to add a volume too.
Once the disk-group is added you can either create a new volume or expand an existing volume. Depending on the host OS there are steps you may need to take if you increase the storage. Please follow those steps to correctly see the storage from the hosts.
Cheers,
Shawn

Re: Process to add new disk array on a MSA2050 with 2 Group disks running in Production?
If you look for only procedure of how to create new VDG and add to the existing Pool then Shawn already shared the same.
From you what we would like to understand,
-> Do you use both Pools?
-> We understand you have two VDG (Virtual Disk Group) but are they part of same Pool or each belongs to different pool ?
--> What is the purpose of creating new VDG with 6 drives ? It means you want to increase space for the existing pool so that you can use this increased space for the existing volumes and new volumes or you want this new VDG for the pool which is not yet used and for future new volumes?
Hope this helps!

Re: Process to add new disk array on a MSA2050 with 2 Group disks running in Production?
Hi, we have this configuration Previously,
Name Health Pool RAID Level Class Total Size Free
10K OK A RAID6 Virtual SAS 7192.0GB 5853.0GB
Cache OK A RAID0 Virtual sSAS 1596.5GB 1012.9GB
7.2k OK B RAID6 Virtual SAS MDL 11.9TB 5097.5GB
But we hace 6 slots empty, and the plan was fill all of them to have another datastore for VMware, i added yesterday, and how is like this array: "10K.NEW"
Name Health Pool RAID Level Class Total Size Free
10K OK A RAID6 Virtual SAS 7192.0GB 5853.0GB
Cache OK A RAID0 Virtual sSAS 1596.5GB 1012.9GB
7.2k OK B RAID6 Virtual SAS MDL 11.9TB 5097.5GB
10K.NEW OK B RAID6 Virtual SAS 4793.9GB 4730.7GB
But im not sure if the setting "Tier Afinitty" should be Performance instead Archive.
And the VGD new is Volumen 3:
Name Pool Size Allocated Size Class Write Policy Optimization Read-ahead Tier Affinity
Volumen 1 A 7191.9GB 1338.9GB Virtual write-back standard Adaptive Performance
Volumen 2 B 11.8TB 6805.5GB Virtual write-back standard Adaptive Performance
Volumen 3 B 4778.9GB 148.1GB Virtual write-back standard Adaptive Archive
Can you please let me know what do you think about this configuration?
Thanks In Advance!
