I inherited an old array that seems easy to manage using Storage Mangement Suite called IBM DS Storage Manager.
I had to extend one of the volumes hosted on that box. So I started up the management GUI, found the box, the correct array, and volume (“Logical drive”), and expected to just right click and add capacity.
I could add disks hence capacity to the array using the GUI but could not find anything about extending the volume.
I had to use my favorite search engine – duckduckgo– and found out that this operation can only be performed from the Shell. Which is actually a special shell utility.
PS C:\Program Files (x86)\IBM_DS\client> .\SMcli.exe 172.17.1.114 -p $#$#@$password
Please type desired command.

After checking the details about the volume, I was able to extend the volume using:
set logicalDrive [COMPANY-TOR-FS2-F”] addCapacity=500 GB;
show logicalDrive [“COMPANY-TOR-FS2-F”] actionProgress;
Logical Drive COMPANY-TOR-FS2-F
Percent Complete: 53%
when growing the volume it does tell you much. Be sure to use the other command to verify the status.
And if you are looking for more information, I found the CLI manual here and not on the IBM website.
