# Challenge 2: VM and Managed Disks - Attach a Data Disk to a VM, Extend and Retype it

# Here is what you will learn 🎯

Create a data disk and attach it to a virtual machine

# Table Of Contents

Create and attach a new disk
Logon to your windows VM and partition the disk
Extend your disk
Cleanup

# Create and attach a new disk

[Azure Portal] 
-> Virtual machines 
-> e.g. 'vmfirst001' 
-> Data disks 
-> "+ Create and attach a new disk"

Name	Value
LUN (aka logical unit number)	e.g. 0
Disk name	e.g. vmfirst001-disk-001
Account type	Standard SSD
Size	128GiB (E10)
Host caching	Read/write

And don't forget the SAVE button!

# Logon to your windows VM and partition the disk

[Azure Portal] 
-> Virtual machines e.g. 'vmfirst001' 
-> Connect 
-> RDP 
-> Download RDP File 
-> open...

Once logged into the VM - execute diskmgmt.msc to open the Disk Manager. Your attached data disk will show up 'uninitialized'.
Initialize:
Partition and format it:

# Extend your disk

To modify an existing disk it must be 'detached' first from the VM:
```
[Azure Portal] 
-> Virtual machines e.g. 'vmfirst001'
-> Disks
```
Detach it

And don't forget the SAVE button!

Find your disk in the resource group and change it's configuration

[Azure Portal] 
-> Resource Groups 
-> rg-firstvm-test-001 
-> vmfirst001-disk-001 
-> Size + performance

The new disk should:
- support 99.9% availabilty
- have 256GiB disk size and support 1100 IOPS disk
TIP

📝 Reference: What disk types are available in Azure? (opens new window)
Attach disk back to VM. Once done it'll show up in the VMs like:

TIP

📝 Attaching data disks can be done with a running VM.

❔ Questions:

How much is a E10 / month? (fix price, variable costs, region differences)

Can a disk be resized without losing its data?

Can I easily downsize a disk?

# Cleanup

Delete the resource group. This will also delete its containing artifacts.

[Azure Portal] 
-> Resource Groups 
-> rg-firstvm-test-001 
-> 'Delete resource group'
