4.14 Postinstallation Checklist
Use the following checklist to make sure you perform all the necessary
postinstallation tasks:
This chapter describes which tasks you should perform prior to beginning an upgrade. Tasks described in this chapter include:
In addition to reviewing the information in this chapter, you might need to refer to the following sources of information as well:
5.1 Notes, Cautions, and Restrictions
This section provides important information that can affect the success
of your upgrade. Review the cautions, restrictions, and notes carefully
before you begin the upgrade.
5.1.1 Spiralog Notes and Restrictions
OpenVMS Alpha Version 7.1 requires a new version of the Spiralog file
system. If you are running prior versions of Spiralog, you must upgrade
to Spiralog Version 1.2, which is available on CD--ROM. Note the
following:
To upgrade to Version 7.1 of the OpenVMS Alpha operating system, you must be running at least Version 6.1, 6.2, or 7.0.
If you are upgrading in a cluster environment, also see Chapter 6
for information about required versions of the OpenVMS Alpha and
OpenVMS VAX operating systems.
5.1.3 Upgrade Paths
Note the following:
To upgrade to OpenVMS Version 7.1, you must have an appropriate license. Digital's software licenses grant the right to use the current version of a product or any previous version of the product at the time of purchase. If you have an OpenVMS license prior to Version 7.1 and are not covered by a Software Product Services agreement, which includes the right to use new versions (RTNV), you must purchase an Update License before upgrading to OpenVMS Version 7.1.
If you do not have an Update License, please contact your Digital
support representative who will assist you in obtaining the correct
Product Authorization Key (PAK) needed to access the OpenVMS operating
system.
5.1.5 Files and Directories
Note the following:
Because you cannot upgrade the operating system on a shadowed system disk (the upgrade will fail), you need to disable shadowing on that disk and perform other operations before you can upgrade the operating system.
There are several methods for creating a nonshadowed target disk. This chapter describes how to change one of your existing shadowed system disks in a multimember shadow set to a nonshadowed disk that you can use as your target disk for the upgrade.
If you have a larger configuration with disks that you can physically
access, you may want to use a copy of the system disk as your
target disk. Volume Shadowing for OpenVMS describes two methods you can use to create
this copy (using volume shadowing commands or BACKUP commands) and how
to disable volume shadowing.
5.2.1 Creating a Nonshadowed Target Disk
Change one of your existing shadowed system disks to a nonshadowed disk as follows:
>>> BOOT -FL 0,1 DKA100
SYSBOOT> SET SHADOW_SYS_DISK 0
SYSBOOT> CONTINUE
If you want to change the label on the upgrade disk, use the DCL command SET VOLUME/LABEL=volume-label device-spec[:] to perform this optional task. (The SET VOLUME/LABEL command requires write access [W] to the index file on the volume. If you are not the volume owner, you must have either a system UIC or the SYSPRV privilege.)
For OpenVMS Cluster systems, be sure that the volume label is a unique name across the cluster.
Note: If you need to change the volume label of a disk that is mounted across the cluster, be sure you change the label on all nodes in the OpenVMS Cluster system. The following example shows how you can use the SYSMAN utility to define the environment as a cluster and propagate the volume label change to all nodes in that cluster:
SYSMAN> SET ENVIRONMENT/CLUSTER SYSMAN> DO SET VOLUME/LABEL=new-label disk-device-name:
Be sure your system is set to boot from the upgrade disk by default.
Use the SHOW BOOTDEF_DEV and SET BOOTDEF_DEV console commands to
accomplish this task. (See Appendix A for more information.)
5.2.4 What to Do Next
After you have created a nonshadowed system disk that you can use for
the upgrade, perform the additional preupgrade procedures described in
the balance of this chapter.
5.3 Backing Up the System Disk
Digital strongly recommends that you make a backup copy of the system
disk and, if your configuration allows it, upgrade the backup
copy. (If there are problems, you will still have a working system
disk.)
5.3.1 How to Back Up the System Disk
To back up the system disk, do the following:
For complete information about backup operations, including a
description of an alternate method that does not require booting from
the operating system CD--ROM, see Appendix B.
5.4 Preparing the System Disk
The following sections describe how to prepare the system disk for the upgrade. The operations include the following:
Examine and repair (if necessary) the system disk using the ANALYZE/DISK_STRUCTURE command. (See the OpenVMS System Management Utilities Reference Manual for more information about this command.) Use the following procedure:
$ ANALYZE/DISK_STRUCTURE SYS$SYSDEVICE
%ANALDISK-I-OPENQUOTA, error opening QUOTA.SYS
$ ANALYZE/DISK_STRUCTURE/REPAIR SYS$SYSDEVICE
It is difficult to determine in advance how many blocks of disk space you will need for the upgrade. It depends on how many files you have on the target disk already and on how many components you select during the upgrade procedure. However, the following information will help:
To see how much space you have on the system disk, enter the following command:
$ SHOW DEVICE SYS$SYSDEVICE
Verify (and modify if necessary) system parameters, described as follows. (If necessary, see the OpenVMS System Manager's Manual for more information about modifying system parameters.) Any system parameters that you modified and did not enter in SYS$SYSTEM:MODPARAMS.DAT are lost during the upgrade. To retain these parameters, enter their names in SYS$SYSTEM:MODPARAMS.DAT and the value that AUTOGEN needs to add to the default minimum value. (When AUTOGEN runs after the upgrade, it uses the values in SYS$SYSTEM:MODPARAMS.DAT.)
For example, if you modified GBLPAGES by 128 pages above the default, add the following line to SYS$SYSTEM:MODPARAMS.DAT:
ADD_GBLPAGES=128
Continue the preupgrade tasks as follows, depending on whether you are upgrading in a standalone or OpenVMS Cluster environment:
IF ... | THEN ... |
---|---|
you are upgrading a standalone system, |
do the following:
|
you are upgrading an OpenVMS Cluster system, |
do the following:
|
Use the following checklist to make sure you have performed all the tasks before beginning the upgrade:
This chapter describes how to prepare to upgrade in an OpenVMS Cluster environment, depending on the type of upgrade you perform and whether you need to add any new computers to the cluster.
Note: Be sure you have performed the preupgrade
tasks described in Chapter 5 before you upgrade your OpenVMS
Cluster system.
6.1.1 Mixed-Version Support
OpenVMS Alpha Version 7.1 and OpenVMS VAX Version 7.1 provide two levels of support for mixed-version and mixed-architecture OpenVMS Cluster systems. These two support types are warranted and migration.
Warranted support means that Digital has fully qualified the two versions coexisting in an OpenVMS Cluster and will answer all problems identified by customers using these configurations.
Migration support is a superset of the Rolling Upgrade support provided in earlier releases of OpenVMS and is available for mixes that are not warranted. Migration support means that Digital has qualified the versions for use together in configurations that are migrating in a staged fashion to a newer version of OpenVMS VAX or to OpenVMS Alpha. Problem reports submitted against these configurations will be answered by Digital. However, in exceptional cases Digital may request that you move to a warranted configuration as part of answering the problem.
Migration support will help you move to warranted OpenVMS Cluster version mixes with minimal impact on your cluster environment. Table 6-1 shows the level of support provided for all possible version pairings.
Alpha V6.2--xxx | Alpha V7.0 | Alpha V7.1 | |
---|---|---|---|
VAX V6.2-- xxx | WARRANTED | Migration | Migration |
VAX V7.0 | Migration | WARRANTED | Migration |
VAX V7.1 | Migration | Migration | WARRANTED |
Note
Digital does not support the use of Version 7.1 with Version 6.1 (or earlier versions) in an OpenVMS Cluster environment. In many cases, mixing Version 7.1 with versions prior to Version 6.2 will successfully operate, but Digital cannot commit to resolving problems experienced with such configurations.
There are two types of cluster upgrades: concurrent and
rolling. The type of upgrade you use depends on whether you
want to maintain the availability of the cluster during the upgrade and
whether you have more than one system disk. Review this chapter and
then perform the preliminary tasks for the upgrade procedure
(concurrent or rolling) that best suits your configuration.
6.1.3 Adding a New System to the Cluster
If you need to add a new computer supported by OpenVMS Alpha Version 7.1 to an existing OpenVMS Cluster configuration, Digital supports two options, listed in the following preferred order:
When you upgrade the operating system in an OpenVMS Cluster environment, be sure the following information is available to review:
This section describes the following:
During a concurrent upgrade, you must shut down the entire cluster and upgrade each system disk. No one can use the cluster until you upgrade each system disk and reboot each Alpha computer. When the cluster reboots, each Alpha computer will be running the upgraded version of the OpenVMS Alpha operating system.
If all Alpha systems in the OpenVMS Cluster environment are booted from
one system disk, you must perform a concurrent upgrade.
6.2.2 Preparing for a Concurrent Upgrade
To prepare for a concurrent upgrade, use the following procedure:
$ @SYS$SYSTEM:SHUTDOWN
This section describes the following:
During a rolling upgrade, you upgrade each system disk individually,
allowing old and new versions of the operating system to run together
in the same cluster, creating a mixed-version cluster.
Because rolling upgrades allow mixed-version clusters, the systems that
you are not upgrading remain available. During a rolling upgrade, you
keep some of the computers in the cluster running while you upgrade
others (you must have more than one system disk).
6.3.2 Notes and Restrictions
Before performing a rolling upgrade, note the following:
To prepare for a rolling upgrade, follow these steps:
$ MCR SYSMAN SYSMAN> SET ENVIRONMENT/CLUSTER SYSMAN> DO SHOW DEVICE disk-name
$ @SYS$SYSTEM:SHUTDOWN
$ [Ctrl/P] >>> D SIRR C >>> C IPC> Q IPC> [Ctrl/Z]
This chapter describes the following tasks:
The OpenVMS Alpha Version 7.1 operating system includes procedures that allow you to easily upgrade the operating system using the POLYCENTER Software Installation utility. In console mode, you can boot the operating system CD--ROM to begin the upgrade procedure. On a system that is already running the OpenVMS Alpha Version 7.1 operating system, you can invoke the upgrade procedure by entering a command at the DCL level.
