Before you install the new version,
back up critical files and information for each server instance. Store
the files in a safe place, on a different system from the system that
is being upgraded or on offline media, such as a CD. The files are
required after the installation of the new software version is complete.
You also need these files if you must revert to the previous version
after the upgrade.
Procedure
- Back up device configuration information to another directory
by using the following Tivoli® Storage
Manager administrative
command:
backup devconfig filenames=file_name
where file_name specifies
the file in which to store device configuration information.
- Back up volume history information to another directory
by using the following Tivoli Storage
Manager administrative
command:
backup volhistory filenames=file_name
where file_name specifies
the file in which to store volume history information. Ensure that
the volume history includes information about the database backup
that you completed in the preceding steps. For example, issue the
following command: query volhistory type=dbsnapshot
Review
the query output to verify that the time stamp for the database backup
matches the actual time of the backup.
- Save copies of the following files, which are in the server
instance directory:
- Server options file, typically named dsmserv.opt
- dsmserv.dsk
Important: The dsmserv.dsk file
is not available in Tivoli Storage
Manager V7.1. Save a
copy of the dsmserv.dsk file in case you must
revert to V5.5.
- In the server instance directory, look
for the accounting log file, dsmaccnt.log. If
the file exists, save a copy.
- Back up any scripts that were used to complete daily housekeeping
for the server. Examine the scripts for changes that are needed after
the upgrade.
- Store the device configuration
file, the volume history file, the server options file, and the other
files in a safe place. Ensure that the files are stored on a different
system from the system that is being upgraded, or on offline media.
