Device description (DEVD)
Specifies the name of the device description.
This is a required parameter.
| Top |
Resource name (RSRCNAME)
Specifies the resource name that identifies the hardware that the description represents.
- *SAME
- The value does not change.
- *NONE
No resource name is specified. A resource name must be provided before the device can be varied on.
- resource-name
Specify the name that identifies the optical device hardware on the system.
Note: Use the Work with Hardware Resources (WRKHDWRSC) command with TYPE(*STG) specified to determine the resource name.
| Top |
Local internet address (LCLINTNETA)
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.
- *SAME
The value does not change.
- *NONE
No internet address is specified. Specifying this value will prevent the use of network virtual image files.
- *SRVLAN
The value that was defined for the service tool server or the operations console (LAN) is specified.
| Top |
Remote internet address (RMTINTNETA)
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.
- *SAME
The value does not change.
- character-value
An IPv4 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.
An IPv6 internet address is specified in the form x:x:x:x:x:x:x:x, where x is a hexadecimal number ranging from 0 through X'FFFF'. "::" may be used once in the IPv6 address to indicate one or more groups of 16 bits of zeros. The "::" may be used to compress leading, imbedded, or trailing zeros in the address. An IPv6 internet address must be a unicast address and must not contain an imbedded IPv4 address (compatibility or mapped). If the internet address is entered from the command line, the address must be enclosed in apostrophes.
| Top |
Network image directory (NETIMGDIR)
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.
- *SAME
The value does not change.
- path-name
Specify the network path on the NFS server containing the virtual image files. Up to 127 characters may be specified.
| Top |
User ID number (UID)
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.
- *SAME
The value does not change.
- 0-4294967295
Specify the ID number of the remote user profile on the NFS server.
| Top |
Group ID number (GID)
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.
- *SAME
The value does not change.
- 0-4294967295
Specify the ID number of the remote group profile on the NFS server.
| Top |
Online at IPL (ONLINE)
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.
- *SAME
- The value does not change.
- *YES
This device is varied on automatically at IPL.
- *NO
This device is not varied on automatically at IPL.

Examples
Example 1: Change an Optical Device To Be Varied On At IPL
CHGDEVOPT DEVD(OPT01) ONLINE(*YES)
This command changes the device description of an optical device that is named OPT01 so that the device is automatically varied on at IPL.
Example 2: Change an Optical Device To Specify an IPv6 Remote Network Internet Address
CHGDEVOPT DEVD(VRTOPT03) RMTINTNETA('fe80::1234')
This command changes the device description of an optical device that is named VRTOPT03 to specify an IPv6 remote network internet address. The device must be varied off for this change to take affect.
