Preparing the HP 3000 MPE V/E System for Migration
DIRMIG allows the system manager to duplicate the MPE V/E operating
environment on the MPE/iX system. The operating environment consists of
account structure information, including the UDC environment, private
volume information, and system tables information. DIRMIG runs on your
MPE/iX-based system and takes as input your MPE V/E SYSDUMP tape. Before
using an MPE V/E SYSDUMP tape and DIRMIG to migrate your operating
environment, please review the following checklists.
Accounting Structure
* Certain MPE/iX accounts and groups are reserved for system use.
Check for accounts and groups on the MPE V/E system that are
reserved on the MPE/iX system (DIAG.SYS, CONFIG.SYS, MPE XL.SYS,
CONFG950.SYS, CONFG925.SYS). DIRMIG will not migrate these groups
and accounts.
* Use :LISTFILE or :LISTFto check for files that exist on both the
MPE V/E system and the MPE/iX system. DIRMIG will not restore
user files that already exist on MPE/iX. Purge duplicate files, or
create groups and accounts on the MPE V/E system to accommodate
duplicate files, if needed. Move duplicate files into new groups
and accounts on the MPE V/E system.
User-Logging ID Table
On the MPE V/E system:
* Use :LISTLOG to determine which user-logging IDs to migrate.
* Use :RELLOG to release user-logging identifiers that should not be
migrated or which are no longer in use.
* Define user-logging parameters via SYSDUMP. This includes the
number of user-logging processes and the number of users per
logging process.
UDCs and User Files
Disable any system-level, account-level, and user-level UDCs that users
do not want to migrate. Run the GETUDC utility on the resultant MPE V/E
system. GETUDC aids in the migration of the MPE V/E UDC environment by
creating a text file containing the names of all system-recognized UDC
files.
Refer to Appendix F, "Using the GETUDC Utility" for details on using
GETUDC.
The GETUDC-generated file should be supplied to SYSDUMP's ENTER DUMP FILE
SUBSET prompt so that all UDC files are stored at the beginning of the
STORE portion of the SYSDUMP tape. Placement of UDC files at the
beginning of the SYSDUMP tape greatly reduces the amount of time DIRMIG
takes to search for and restore these files.
Create a SYSDUMP Tape
DIRMIG requires an MPE V/E SYSDUMP tape as input. Accomplish these tasks
when running SYSDUMP:
* Delete unused global RINs that should not be migrated. Configure
RIN parameters.
* Define user-logging parameters. Configure appropriate use-logging
ID parameters, including the number of user-logging processes and
the number of users per logging process.
* Enter the name of the GETUDC-generated text file at the SYSDUMP
prompt ENTER DUMP FILE SUBSETS.
NOTE A non-carriage-return full backup is recommended.
Preparing to Perform Migration
Ensure that all necessary components are available before continuing.
A Hewlett-Packard representative should have installed and configured the
900 Series HP 3000. Check to be sure that the system is up and loaded.
NOTE Please refer to the HP 3000 Computer Systems System Configuration
Guide (5954-9354) for current information on supported peripherals.
Software Requirements
An MPE/iX load tape, and a SYSDUMP tape from an MPE V/E-based system are
required to complete system migration.
