Specifies the resource name that identifies the hardware that the description represents.
No resource name is specified. A resource name must be provided before the device can be varied on.
The resource name will be generated by the operating system at the time the device description is created. The resource name will represent virtual (not physical) hardware. Once the IBM i has created the maximum number of virtual hardware resources, the last created resource will be used for the device description.
Note: The resource name will not be removed if a device description is deleted. You may create a new device description for existing resources by specifying the resource by name.
Specify the name that identifies the media library device hardware on the system.
Note: Use the Work with Hardware Resources (WRKHDWRSC) command with TYPE(*STG) specified to determine the resource name.
| Top |
Specifies the type of device this description represents.
Note: If the type (TYPE) parameter specified is not valid for the resource name (RSRCNAME) parameter specified, the OS will automatically configure the TYPE parameter.
The device type is determined from the resource name (RSRCNAME) parameter.
For a list of the device types that are valid on this parameter, press F4 (Prompt) from the TYPE prompt.

Specifies the TCP/IP interface to be used to communicate with the remote system when using virtual image files on a network.
Note: This parameter is not valid if *NONE is specified for the Resource name (RSRCNAME) parameter, or if any value except 632B or *RSRCNAME is specified for the Device type (TYPE) parameter.
No internet address is specified. Specifying this value will prevent the use of network virtual image files.
The value that was defined for the service tool server or the operations console (LAN) is specified.
| Top |
Specifies the remote internet address of the Network File System (NFS) server where this virtual optical device will look for virtual image files.
Note: A value is required for this parameter if *SRVLAN is specified for the Local internet address (LCLINTNETA) parameter.
The internet address is specified in the form, nnn.nnn.nnn.nnn, where nnn is a decimal number ranging from 0 through 255. Leading zeros in each part of the dotted decimal internet address are invalid and will be removed. An internet address is not valid if it has a value of all binary ones or zeros for the network identifier (ID) or host portion of the address. If the internet address is entered from the command line, the address must be enclosed in apostrophes.
| Top |
Specifies the network path on the Network File System (NFS) server containing the virtual image files that were prepared for use with this device.
Note: A value is required for this parameter if *SRVLAN is specified for the Local internet address (LCLINTNETA) parameter.
Specify the network path on the NFS server containing the virtual image files. Up to 127 characters may be specified.
| Top |
Specifies the ID number of the remote user profile on the Network File System (NFS) server.
Note: This parameter is only valid if *SRVLAN is specified for the Local internet address LCLINTNETA parameter.
Specify the ID number of the remote user profile on the NFS server.
| Top |
Specifies the ID number of the remote group profile on the Network File System (NFS) server.
Note: This parameter is only valid if *SRVLAN is specified for the Local internet address LCLINTNETA parameter.
Specify the ID number of the remote group profile on the NFS server.
| Top |
Specifies whether this object is automatically varied on at initial program load (IPL).
Note: The value for this parameter will be set to *NO if *SRVLAN is specified for the Local internet address LCLINTNETA parameter.
This device is varied on automatically at IPL.
This device is not varied on automatically at IPL.
| Top |
Specifies the message queue to which operational messages for this device are sent.
Single values
Messages are sent to the system operator message queue (QSYS/QSYSOPR).
Qualifier 1: Message queue
Specify the name of the message queue to which operational messages are sent.
Qualifier 2: Library
All libraries in the job's library list are searched until the first match is found.
The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.
Specify the name of the library to be searched.
| Top |
Specifies the text that briefly describes the object.
| Top |
Specifies the authority you are giving to users who do not have specific authority for the object, who are not on an authorization list, and whose group profile or supplemental group profiles do not have specific authority for the object.

Example 1: Create an Optical Device Description
CRTDEVOPT DEVD(OPT01) RSRCNAME(*OPT01) TYPE(*RSRCNAME)
This command creates a device description for an optical device that is named OPT01. The device type is determined from the resource name.
Example 2: Create a Virtual Optical Device Description
CRTDEVOPT DEVD(VRTOPT01) RSRCNAME(*VRT) TYPE(*RSRCNAME)
This command creates a device description for a virtual optical device that is named VRTOPT01. The device type is determined from the resource name. All virtual optical devices will be assigned a TYPE value of 632B.
Example 3: Create a Virtual Optical Device Description When Using Virtual Image Files on a Network
CRTDEVOPT DEVD(VRTOPT02) RSRCNAME(*VRT) LCLINTNETA(*SRVLAN)
RMTINTNETA('9.5.1.1')
NETIMGDIR('/Mypath/My Catalog Directory')
UID(123) GID(26) ONLINE(*NO)
This command creates a device description for a virtual optical device that is named VRTOPT02. The device type is determined from the resource name. All virtual optical devices will be assigned a TYPE value of 632B. The MODEL will be 003, since the value *SRVLAN is specified for LCLINTNETA. The device will look for virtual image files using the Network File System (NFS) server internet address specified for RMTINTNETA. The path name on the remote NFS server specified for NETIMGDIR will be used to locate the virtual image files. The user ID number specified for UID and the group ID number specified for GID identify the profiles that will be used on the remote NFS server. The device will not be varied on automatically at IPL.
