On OpenVMS I64 systems only, a diagnostic partition
is created.
The diagnostic partition is visible only from the console;
it corresponds to the contents of SYS$MAINTENANCE:SYS$DIAGNOSTICS.SYS
on the system disk. The partition is intended and reserved for
use by HP Services (it is used with the HP IPF Offline Diagnostics
and Utilities CD provided with the purchase of your Integrity server).
For more information about offline diagnostics, see your hardware
documentation and the following Web site:

HP recommends creating the system disk with this
partition and not removing it. However, it is not required for
operation of OpenVMS.
If you do not want the diagnostic partition, you can prevent
its creation by initializing the disk before installing OpenVMS,
performing the steps described in “Alternative Method of Initialization”. Alternatively, if you have already created
the system disk and the partition, you can remove it by performing
the steps described in “Removing the Diagnostic Partition File (I64
Only)”.
