Checklist

The checklist is a tool to ensure you remember to perform all steps in the how-to article. It provides an overview with the option to drill down into the how-to guide. If possible make the checklist chronological.

Ensure the storage increase is authorised and has a Jira ticket
Login to the customers Azure Portal
Locate the correct server
Add the desired disk size and type
RDP to the server
Configure the disk in Disk Management
Confirm the storage expansion in Windows Explorer
Update the config log



Things to be aware of!

Be sure that the disk size is below 1028GB for 1TB, otherwis we will be charged for 2TB. Azure has set disk sizes if the size is incorrect we will be charged for next disk size up, see the table below.

EG to add 10TB select and S40 (2TB) and S60 (8TB)



How-to guide:

  • Login to the customers Azure portal

  • Browse to the desired Virtual Machine by clicking in the search box and selecting Virtual Machines

  • Select the desired Virtual Machine from the list, usually this will be an App server

  • Once the Virtual Machine page is displayed select disks on the left hand side

  • Once the disk page is displayed, select Add data disk

  • You will then be presented with some options, disk name, size, etc

  • The top half of the form should look similar to this once completed

  • In the bottom half of the form we need to select a storage account to be used as these are unmanaged disks (managed disks select the storage account automatically)

  • Scroll down and click on Browse to select the storage account to be used

  • After clicking on Browse select the desired storage account

  • Then select the desired container to be used

  • Click select

  • Then click OK

  • The disk is now added and visible in the list, set the Host Caching to match the other disks and all looks correct, click Save

  • Azure will now update the virtual machine with the new disk configuration

  • After Azure has completed the updating it should look like this

  • We now need to complete the remainder of this task on the server itself, so logon to the server over RDP

  • Once you are on the server open an MMC by clicking start and MMC (Microsoft Management Console)

  • Open MMC and select File > Add Remove Snapin

  • Now select Disk Management > Add

  • Ensure This Computer is selected and click Finish

  • Click OK

  • In the Console root double click Disk Management

  • Click OK to Initialize the new disk

  • Identify the drive you wish to expand

  • Right click on the drive and select Extend Volume

  • This opens the Extend Volume wizard click next

  • Select the disk in Available and click Add

  • Click Next

  • Click Finish

  • Click Yes on the Disk Management dialogue box

  • Browse to This PC in Windows explorer to confirm the disk space is now expanded by 1TB

  • The final step is to update the customers config log to include this storage expansion
