Access the ISO Disk Image

OpenVMS provides a mechanism to mount an ISO image of a CA OpenVMS product CD/DVD directly. These steps are valid for OpenVMS Alpha 7.3-2 and newer, and OpenVMS I64 8.2-1 and newer.

Notes:

OpenVMS Alpha users should start at step 1; OpenVMS I64 users should start at step 4.
Steps 1 and 2 only need to be performed once on systems running OpenVMS Alpha 7.3-2, but are unnecessary for systems running OpenVMS Alpha 8.2 and newer.

To access the ISO disk Image

Edit the file SYS$STARTUP:CDRECORD.COM using any suitable text editor.
Search for the text “load_ldcld:”. The line immediately following the occurrence of this text should be “$ set command sys$input”. Starting with the line immediately after the line that reads "$ set command sys$input", cut all lines of text up to but not including the line that reads "$ RETURN 1" into a file named LD.CLD; this will be approximately 245 lines of text.

The first few and last few lines of the selected text should look as follows:
```
  !+++ 
```
```
  ! 
```
```
  ! Facility: 
```
```
  ! 
```
```
  ! Command Definition File for the LD Utility. 
```
```
  ! 
```
```
  ! Abstract: 
```
```
  ! 
```
```
  ! This file defines the following commands; 
```
```
  . 
```
```
  . 
```
```
  . 
```
```
  DEFINE SYNTAX PARAM_ALL 
```
```
  PARAMETER P1,LABEL=COMMAND,PROMPT="Command",
```
```
  VALUE(REQUIRED,TYPE=LD_OPTIONS) 
```
```
  PARAMETER P2,LABEL=DEVICE,VALUE(TYPE=$DEVICE)
```
```
!<end-of-file> 
```

Edit the file SYS$STARTUP:LD$STARTUP.COM and search for a line of text that reads:

$ if f$file_attributes("sys$system:ld$utility.exe","known")

Insert the following lines of DCL immediately before that line:

$ if f$file_attributes("sys$message:ld$msg.exe","known")

$ then

$   install replace sys$message:ld$msg.exe

$ else

$   install create sys$message:ld$msg.exe

$ endif

Close the file and terminate your editing session.

Add the LD command to your command tables. For OpenVMS Alpha 7.3-2, you will use the LD.CLD file that you created in step 1 as follows:
```
$ SET COMMAND LD
```
```
For OpenVMS Alpha 8.2 and up, execute the following:
```
```
$ SET COMMAND SYS$UPDATE:LD.CLD
```
The above commands should be executed whenever you login.
Start the logical disk facility by executing the new version of LD$STARTUP.COM created in STEP 3. This only needs to be executed once after each system boot:
```
$ @SYS$STARTUP:LD$STARTUP.COM
```
Download the .ISO image of the product(s) that you wish to install and record the location where you have placed them on your OpenVMS system. These files must be transferred using a transfer type of “binary”.
Connect the .ISO image to a logical disk device using the command:
```
$ LD CONNECT disk:[dir-path]filename.ISO
```
The system responds with the device name of the logical disk device that the .ISO file was connected to. You will need this device name for the following step.

Mount the logical disk device using the command:

$ MOUNT/MEDIA=CD/OVER=ID logical-disk-device-from-step-6

Follow the installation guide for the product that you are installing by substituting the name of the logical disk device for the name of the CDROM or DVD device where indicated in the product installation guide.
Repeat steps 6 and 7 for each ISO image for the products that you wish to install.
When you have completed the installations, dismount and disconnect each logical disk using the following commands.
```
$ DISMOUNT LD-device-name
```
```
$ LD DISCONNECT LD-device-name
```
You can do this after you complete each installation and before repeating steps 6 and 7 for other ISO product disk images, or after you have completed all installations. If you do this after all installations, repeat these commands once for each ISO product disk image that was connected and mounted.
