You add a hard drive to the virtual machine for two reasons: 1) Before adding a cache device to the NAS Bridge, you must have an available virtual machine hard drive. 2) If you are upgrading the NAS Bridge, you must add a hard drive.
Before you begin
You must be familiar with VMware vSphere and ESXi, and you must have experience managing virtual machines in this environment.
Steps
- Before adding a hard drive to use as a cache device, view a list of the drives already in the system so that you will recognize the name of the new drive.
Attention: You must know the name of the new hard drive when you add it as a cache device. If you select the wrong drive, you lose access to your NAS Bridge file systems.
- At the command line on the administrative server, run the following command:lsblk
Example
A list of hard drives appears. For each drive, details such as the name and the capacity (size) are shown.

- Take a screen shot or make a note of the output of the lsblk command.
- Sign in to the VMware vSphere Web Client.
- Locate the NAS Bridge virtual machine.
- Edit the virtual machine settings and add a new hard drive.
- Select the location for the hard drive and click OK.
- Scan the host bus to ensure that the new drive is recognized by the Linux operating system.echo "- - -" | sudo tee /sys/class/scsi_host/host*/scan
- Run the lsblk command again to verify that the new hard drive is listed.
Example
The hard drive named
sdb has been added.

- If you will be using this hard drive as a cache device, record the name of the hard drive you added so that you can select the correct drive when you add a cache device.
The hard drive name is listed as /dev/name in the NAS Bridge web interface's Cache Devices page.
