1. In the primary address space, the first and last page numbers are treated as
real addresses. They are prefixed with the prefix register value of the base
virtual CPU of the target virtual machine.
In other address spaces, the first and last page numbers are treated as
absolute addresses. Prefixing is not applied to these addresses.
2. Only specify the page numbers for the fields firstpage and lastpage. For
example, to unlock storage locations X'12000' to X'2CFFF' of USERA’s primary
address space, enter the following command:
unlock usera 12 2c
3. The LOCK command issued for a user ID’s storage operates independently of
the DIAGNOSE X'98' page locking facility. Pages locked by command cannot be
unlocked by DIAGNOSE X'98', nor can real I/O pages locked by DIAGNOSE
X'98' be unlocked by command.
4. If you enter LOCK to lock a page in a shared segment and do not enter an
UNLOCK, the page is unlocked when the last user of the shared segment
releases the storage with the LOGOFF command or another command that
clears storage.
