Setting up the virtual optical device on the client system for installing IBM® i

After you set up the Network File System server to share images, proceed with these steps to set up a virtual optical device on the client.

To set up the virtual optical device type 632B-003 on the client, follow these steps.

If your system uses a LAN console, then proceed to step 2. To configure a service tools server for the virtual optical device to use, see Configure a service tools server for DST for the virtual optical device to use.
Create a device description for the virtual optical device. For example:
```
CRTDEVOPT DEVD(virtual_device_name) RSRCNAME(*VRT) LCLINTNETA(*SRVLAN) 
RMTINTNETA('X.X.XXX.XXX') NETIMGDIR('/catalog_directory')   
```
- The RMTINTNETA is the remote IP address of the Network File system (NFS) server where this virtual optical device looks for virtual image files.
- The NETIMGDIR parameter specifies the network path on the Network File System (NFS) server containing the virtual image files that were prepared for use with this device. The path is limited to 127 characters. The character set is limited to A-Z, a-z, 0-9, and / (slash).
Vary on the virtual optical device. The virtual_device_name specified on the VRYCFG command is the same as the name specified for DEVD on the CRTDEVOPT command. For example:
```
VRYCFG CFGOBJ(virtual_device_name)  CFGTYPE(*DEV) STATUS(*ON)
```

To confirm that the device is working, use the following commands on the client system to allow you to work with image files.

The Work with Optical Volumes (WRKOPTVOL) command shows a list of optical volumes that are known to the system. The WRKOPTVOL command shows the volume that is mounted in the device.

The Work with Image Catalog Entries (WRKIMGCLGE) command is used to work with the entries for the specified virtual optical device. The WRKIMGCLGE command shows the mounted and loaded volumes. You must specify IMGCLG(*DEV) and the NFS backed optical device for the DEV parameter. For example:

WRKIMGCLGE IMGCLG(*DEV) DEV(target-device-description)

The TFTP command can be used to verify that the setup steps for TFTP processing were done correctly on the server. For example:
```
tftp <server_system> get /catalog_dir/bootp/netipl
```
A message similar to the following is displayed:
```
