Prepare a temporary virtual machine disk

This topic describes how to create a temporary disk to contain the Access Gateway Microsoft Azure disk image. Clone the image and associate it with a virtual machine (VM) by attaching the disk to the VM.

To prepare a disk mounted on a Microsoft Azure VM:

Connect to the VM using the IP address that was generated from the task you performed in Create a temporary virtual machine to host the disk.
```
ssh okta@AA.BB.CC.DD.
```
Find the disk using the dmesg| grep "SCSI disk" command.
```
# dmesg | grep "SCSI disk"
[    2.234786] sd 3:0:1:0: [sdb] Attached SCSI disk
[    2.243805] sd 0:0:0:0: [sda] Attached SCSI disk
[    2.503937] sd 5:0:0:0: [sdc] Attached SCSI disk
```
Note:
Ubuntu 18.04 uses two disks by default: /dev/sda and /dev/sdb. The disk produced by the task in Create a temporary virtual machine to host the disk is /dev/sdc.
Confirm which disks are in use using a command like df -h | grep /dev/sd. This produces output like this:
```
/dev/sda1        29G  1.4G   28G   5% /
/dev/sda15      105M  4.4M  100M   5% /boot/efi
/dev/sdb1        16G   45M   15G   1% /mnt 
```

Create a primary disk partition using the sudo fdisk /dev/sdc command.

sudo fdisk /dev/sdc
. . . 
Command (m for help) n
Partition type
p   primary (0 primary, 0 extended, 4 free)
e   extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-1048575999, default 2048):
Last sector, +sectors or +size{K,M,G,T,P} (2048-1048575999, default 1048575999):[cr]
Command (m for help): w

Syncing disks.

Create a pfile system on the disk using the sudo mkfs -t ext4 /dev/sdc1 command.

sudo mkfs -t ext4 /dev/sdc1
mke2ds 1.44.1 . . .

Writing superblocsl and filesystem accounting information: done

Create a mount point for the new disk using the mkdir command.
```
sudo mkdir /datadrive
```
Mount the disk to the new mount point using the mount command.
```
sudo mount /dev/sdc1 /datadrive
```

Determine the UUID of the disk using the blkid command.

sudo -i blkid  | grep sdc1
/dev/sdc1: UUID="1fcbf355-d641-4fcf-8817-0b4b492413ac" TYPE="ext4" PARTUUID="75642bad-01"

Add an entry to the /etc/fstab disk.

sudo nano /etc/fstab
UUID="1fcbf355-d641-4fcf-8817-0b4b492413ac"      /datadrive   ext4   defaults,nofail   1 2

Reboot the VM, reconnect, and then verify that the new file system is mounted.
```
sudo shutdown -r now
ssh okta@ip address
df -h | grep sdc1
```
The new device should show approximately 467 gigabytes of free space.
