Creating the Diagnostic Partition (OpenVMS I64 Only)

If you have an OpenVMS I64 system disk that does not have the HP-recommended diagnostic partition, you can create one as follows:

Check if the required directory is present by entering the following command:
```
$ DIRECTORY target-disk:[VMS$COMMON]SYSMAINT.DIR
```
If the directory file is not found, create it with the following command:
```
$ CREATE/DIRECTORY target-disk:[VMS$COMMON.SYSMAINT]
```

Create the diagnostic partition file with the following commands.

$ DEFINE/NOLOG/USER DIAG$FILE -
_$ target-disk:[VMS$COMMON.SYSMAINT]SYS$DIAGNOSTICS.SYS
$  RUN SYS$SYSTEM:EFI$CP
EFI$CP> /INIT /CREATE /SIZE=600000 /CONTIGUOUS /DEVICE_ALIAS=alias: DIAG$FILE
EFI$CP> EXIT

Set the file to disable movefile operations:

$ SET FILE/NOMOVE target-disk:[VMS$COMMON.SYSMAINT]SYS$DIAGNOSTICS.SYS

Reset the boot block by invoking the SET BOOTBLOCK command at the DCL prompt, as in the following example, where target-disk is the device on which your target system disk is mounted:
```
$ SET BOOTBLOCK /PRESERVE=SIGNATURE target-disk:[VMS$COMMON.SYS$LDR]SYS$EFI.SYS
```
The /PRESERVE=SIGNATURE qualifier causes the existing Globally Unique Identification (GUID) to be preserved. If you want to reset the GUID, do not use this qualifier.

Partitions on OpenVMS I64 System Disks

This section applies to OpenVMS I64 only; OpenVMS Alpha system disk do not use partitions.

Typically, an OpenVMS I64 disk with no SYS$DIAGNOSTICS.SYS file has three partitions and, therefore, three block devices (blk) visible from the EFI menu, as well as one file system (fs). A disk with the SYS$DIAGNOSTICS.SYS file has five block devices and two file systems.
