System Management Release Notes
5.5 OpenVMS Galaxy Version 7.3
5.5.5 MOP Booting Restrictions
V7.2
In an OpenVMS Galaxy computing environment, MOP (Maintenance Operations
Protocol) Booting is only supported on Instance 0. This restriction will be
removed in a future release.
5.5.6 Restriction on KFMSB and CIXCD Adapters in Galaxy Configurations
Permanent Restriction
Due to firmware addressing limitations on driver-adapter control data structures,
KFMSB and CIXCD adapters can only be used on hardware partitions based at
physical address (PA) = 0. In OpenVMS Galaxy configurations, this restricts their
use to Instance 0.
5.6 LAN ATM (Alpha Only)
This section contains a release note pertaining to the local area network (LAN)
asynchronous transfer mode (ATM) software.
5.6.1 Requirements/Restrictions Using DAPBA/DAPCA Adapters for LAN
Emulation over ATM (Alpha Only)
V7.3
The DAPBA (155 Mb/s) and the DAPCA (622 Mb/s) are ATM adapters for PCI-bus
systems that are supported by SYS$HWDRIVER4.EXE.
Both adapters require a great deal of non-paged pool, and therefore, care should
be taken when configuring them. For each DAPBA, Compaq recommends
increasing the SYSGEN parameter NPAGEVIR by 3000000. For each DAPCA,
Compaq recommends increasing NPAGEVIR by 6000000. To do this, add the
ADD_NPAGEVIR parameter to MODPARAMS.DAT and then run AUTOGEN.
For example, add the following command to MODPARAMS.DAT on a system with
two DAPBAs and one DAPCA:
ADD_NPAGEVIR = 12000000
The following restrictions apply to the DAPBA and DAPCA adapters:
• The adapter cannot be located on a PCI bus that is located behind a PCI-to-
PCI bridge.
• Classical IP is not supported.
5.7 Lock Manager
This section contains notes pertaining to the lock manager.
5.7.1 Lock Manager System Parameter Renamed (Alpha Only)
V7.3
The OpenVMS Performance Management incorrectly refers to the LOCKMGR_
CPU system parameter in its discussion of the Dedicated CPU lock manager.
The LOCKMGR_CPU system parameter name has been changed to LCKMGR_
CPUID.
