The instructions below will help you add a new disk to a Disk Group, then expand a virtual disk:
Step 1 - Adding a drive to a Disk Group
- Open the Dell Modular Disk Storage Manager
- Click the Modify Tab
- Click Add Free Capacity (Physical Disks)
- Follow the prompts (this is the easy part)
Step 2 - Expanding a Virtual Disk
- Determine the amount of space you wish to add in bytes. I recommend that you use this calculator.
- On the computer running Dell Modular Disk Storage Manger, open a command prompt.
- Navigate to Program Files\Dell\MD Storage Manager\Cli
- Use the smcli command to expand the disk. Examples below:
smcli ArrayName -c "set virtualDisk ["virtualdiskname"] addCapacity=virtualdiskcapacityinbytes;"
Lets say I have a:
MD3000i called Array001
A Virtual Disk called VD_Test
And I wanted to add 136 GB of space.
The command would look like this:
smcli -n Array001 -c "set virtualdisk [\"VD_Test\"] addCapacity=146028888064;"
Now this expands the virtual disk on the MD3000i, but the OS will not recognize it. You will need to use Disk Manager to expand the volume in Windows. In our case, we're using the MD3000i as a XenServer storage repository. There will be a future article on expanding the XenServer SR.
