Upgrading to 6.04.01
This appendix provides the following upgrade and downgrade procedures:
• Upgrading VTS — Describes how to upgrade a VTS server to 6.04
Note If GFS is used in your environment, refer to Upgrading a GFS cluster on page 192
to upgrade to GFS version 6.1.
• Downgrading a 6.04 server — Describes how to downgrade the server to the previously
installed version after the 6.04 upgrade
WARNING The following procedures are intended for Linux system administrators. If you
are not proficient in Linux administration and do not have expert knowledge of
the VTS hardware, you could irrevocably damage the system. You are strongly
advised to contact your authorized support representative for assistance.
Upgrading VTS
You can upgrade the VTS server from any interim release level of 6.03.39, 6.03.41, or 6.03.42.
To upgrade from version 6.03.31, you must upgrade to 6.03.37 first. To upgrade from version
6.03.37, you must upgrade to 6.03.39 first. Contact your authorized service and support
representative for assistance. If you have multiple VTS servers in your environment, it is
recommended that you upgrade all VTS servers in your environment.
Preparing to upgrade
Before beginning the upgrade, perform the following:
• Obtain license keys to enable virtual tape drives (VTDs). You can also enable licensing for
optional features — SecureVTS, Instant DR, and AutoCopy (Instant DR and AutoCopy
are licensed together). Obtain a set of license keys for each VTS server in your
environment. Contact your authorized service and support representative for assistance.
• Confirm that at least 800MB of free disk space is available on the server before starting
the upgrade.
• If VTS will be upgraded from 6.03.39 or 6.03.41, or if VTS will be upgraded from 6.03.42
and SecureVTS was not licensed on the 6.03.42 server, you must obtain the vpd.enc file
(referred to as the Vital Product Data, or VPD, file) from your authorized support
representative. For licensing, the VPD file (contains the serial number of the system,
which is used when validating keys for all licensed features of VTS. For encryption, it
contains a tricryption ID that enables VTS to communicate with the key server.
