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. 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. You can configure the service tools server to be available when your system is powered on to dedicated service tools (DST).
Create a device description for the virtual optical device. For example:
```
CRTDEVOPT DEVD(NETOPT) RSRCNAME(*VRT) LCLINTNETA(*SRVLAN) 
RMTINTNETA('X.X.XXX.XXX') NETIMGDIR('/pubs')   
```
- The RMTINTNETA is the remote internet 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 should be 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 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 only shows the volume that is mounted in the device.
The Work with Image Catalog Entries (WRKIMGCLGE) command allows you 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)
```
