System Management Release Notes
5.9 OpenVMS Cluster Systems
5.9.9 Selective Autoconfiguration Not Supported in Some Fibre Channel and
SCSI Configurations
V7.2-1
OpenVMS Alpha provides SYSMAN commands that enable system managers to
specify which devices will be autoconfigured. Device autoconfiguration can be
specified permanently so that it is applied either at each system boot or for the
duration of a manual autoconfiguration command, using the following qualifiers:
SYSMAN> IO SET/EXCLUDE=(device_name)
SYSMAN> IO AUTOCONFIGURE [/EXCLUDE=(device_name)] [/SELECT=(device_name)]
You can use the /EXCLUDE and /SELECT qualifiers to exclude and include Fibre
Channel port driver devices (PG and FG) and any SCSI port driver devices (PK).
However, you cannot use these qualifiers to exclude or include any of the following
device types:
SCSI class-driver devices (DK, MK, GK) whose names include a port
allocation class or an HSZ allocation class
Fibre Channel class-driver devices (DG, GG)
This restriction also applies to SCSI devices on OpenVMS Alpha Version 7.1
systems, if the SCSI device names include a port allocation class.
5.9.10 SHOW Command Displays Wrong Device Type for Fibre Channel
Devices (VAX Only)
V7.2
Fibre Channel devices can be served to OpenVMS VAX systems. On OpenVMS
VAX Version 7.2 (and later) systems, issuing the SHOW DEVICE/FULL command
for a Fibre Channel device ($1$DGAxxxx) incorrectly displays a device type of
Snapshot-capable virtual disk device
. For example:
$ SHOW DEV/FULL $1$DGA1000
Disk $1$DGA1000: (CRNPOP), device type Snapshot-capable virtual disk device, is
online, mounted, file-oriented device, shareable, available to cluster, error
logging is enabled.
The device type in this case should be DEC HSG80.
5.9.11 MEMORY CHANNEL Rolling Upgrade Restriction (Alpha Only)
V7.3
OpenVMS Version 7.3 supports rolling upgrades in an OpenVMS Cluster system,
as described in Section 1.2.
This note applies to rolling upgrades from OpenVMS Alpha Version 7.1 (or a
Version 7.1 variant) to one of the following:
OpenVMS Alpha Version 7.2x
OpenVMS Alpha Version 7.3
If MEMORY CHANNEL adapters (CCMAA-xx) have been added to the cluster
before upgrading OpenVMS to either Version 7.2 (or a Version 7.2 variant) or to
Version 7.3, an MC_FORCEDCRASH bugcheck occurs on the first system when
the second and subsequent systems perform AUTOGEN and SHUTDOWN during
their installation. This problem is caused by conflicting system parameters.
