Object Attribute Description/Verification
Opcom classes
Transports
The Opcom class is defined in the domain object as an Opcom
class when the node was created. Ensure that this is the Opcom
class for this particular node.
Ensure that the transport displayed is the one that you want for
this particular node. The conversion program cannot identify
the transports that you want and hence takes only the defaults.
POOL Description Ensure that you provide the appropriate description for the
pool(s) after the conversion is completed. By default, the
description is not provided during the conversion.
Authorized
users
Ensure that the comma separated list contains the names of all
the authorized users for the pool. The format for specifying an
authorized user must be:
NODE::user
Default users
Ensure that you specify the default users for the pool as the conversion
program does not provide the default users list. The format
for specifying a default user must be:
NODE::user.
VOLUME
The conversion program provides all the necessary attributes.
Type the following command to view the complete volume
attributes.:
MDMS SHOW VOLUME /FULL
B.2.4.1.5 Upgrading the Domain to MDMS V4.x –
Upgrading your SLS/MDMS V2 domain starts with the nodes, which have been defined as database
servers in symbol DB_NODES in file TAPESTART.COM. See HP Archive Backup System
for OpenVMS Installation Guide for details on how to execute the following steps:
1. Shut down all SLS/MDMS database servers in your SLS/MDMS domain.
2. Install version MDMS V4 on nodes that were acting as database servers previously.
3. When the new servers are up-and-running, veify and if possible change the configuration
and database entries so that they match your previous SLS/MDMS V2 setup.
4. Edit SYS$MANAGER:MDMS$SYSTARTUP.COM and ensure that:
– Logical name MDMS$DATABASE_SERVERS includes the current node’s DECnet
(Phase IV) node name.
– Logical name MDMS$PREV3_SUPPORT is set to TRUE to enable the SLS/MDMS
V2 support function in the new server.
– Logical name MDMS$VERSION3 is set to TRUE to direct ABS and/or HSM to use
the new MDMS V4 interface.
If you had to change any of the previous logical name settings, you have to restart the
server by executing the following command procedure :
$ @SYS$STARTUP:MDMS$STARTUP RESTART
You can type the server's logfile to verify that the DECnet listener for object SLS$DB
has been successfully started.
