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).
6.5.2 Notes and Restrictions
The following restrictions apply to rolling upgrades. See the OpenVMS Version 7.3 Release Notes for additional compatibility issues and restrictions.
Any attempt to access the target disk from the remaining OpenVMS Cluster members will corrupt the target disk in most cases. Even if the target disk is mounted only by a remaining cluster member, and no file access is done, the target disk will probably be corrupted. If a disk is corrupted in this way, the only supported recovery is to restore the backup copy of the corrupted disk. |
To prepare for a rolling upgrade:
$ 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 Compaq OpenVMS Alpha Version 7.3 operating system includes
procedures that allow you to easily upgrade the operating system using
the POLYCENTER Software Installation utility. To get started, boot the
Compaq OpenVMS Alpha operating system CD-ROM either from your
local CD-ROM drive or from a CD-ROM
drive connected to the InfoServer, as described in the following
sections.
7.1.1 Booting from the Local Drive
To boot the operating system CD-ROM from the local drive, follow these steps:
BOOT -FLAGS 0,0 source-drive |
Substitute the device name of the CD-ROM drive (as
listed in the SHOW DEVICE display) for source-drive.
For
example, if the SHOW DEVICE display lists the device name of your
CD-ROM drive as DKA400, enter the following command
and press the Return key:
>>> BOOT -FLAGS 0,0 DKA400 |
To boot the operating system CD-ROM using the InfoServer, follow these steps:
>>> BOOT -FLAGS 0,0 -FILE APB_073 lan-device-name |

If you boot the Compaq OpenVMS Alpha operating system CD-ROM from an InfoServer system but lose your connection during the upgrade procedure (the system is unresponsive and pressing Ctrl/Y does not return you to the menu), do the following:
|
The following sections describe how to upgrade from the operating
system CD-ROM.
7.2.1 Upgrading from the CD-ROM
After you boot the operating system CD-ROM, choose the upgrade option (1) from the menu displayed on the screen. The display is similar to the following:
OpenVMS (TM) Alpha Operating System, Version x7.3-76H Copyright (c) 2001 Compaq Computer Corporation. All rights reserved. Installing required known files... Configuring devices... **************************************************************** You can install or upgrade the OpenVMS Alpha operating system or you can install or upgrade layered products that are included on the OpenVMS Alpha operating system CD-ROM. You can also execute DCL commands and procedures to perform "standalone" tasks, such as backing up the system disk. Please choose one of the following: 1) Upgrade, install or reconfigure OpenVMS Alpha Version x7.3-76H 2) Display products and patches that this procedure can install 3) Install or upgrade layered products and patches 4) Show installed products 5) Reconfigure installed products 6) Remove installed products 7) Execute DCL commands and procedures 8) Shut down this system Enter CHOICE or ? for help: (1/2/3/4/5/6/7/8/?) 1 |
The Compaq OpenVMS Alpha operating system CD-ROM may contain patch kits. If it does, information similar to the following will be displayed:
The following PATCH kits are present on the OpenVMS Alpha distribution media. ----------------------------------- ----------- ---------- PRODUCT KIT TYPE KIT FORMAT ----------------------------------- ----------- ---------- DEC AXPVMS UCXECO_42_1 V1.0 Patch Sequential ----------------------------------- ----------- ---------- 1 item found Please consult the OpenVMS Alpha Upgrade and Installation Manual, the Release Notes, and the Cover Letter to determine if any or all of these patches may be required for your system. |
After you choose the upgrade option, the system displays the following information and prompts:
*********************************************************** The installation procedure will ask a series of questions. () - encloses acceptable answers [] - encloses default answers Type your response and press the <Return> key. Type: ? - to repeat an explanation ^ - to change prior input (not always possible) Ctrl/Y - to exit the installation procedure There are two choices for Installation/Upgrade: INITIALIZE - removes all software and data files that were previously on the target disk and installs OpenVMS Alpha. PRESERVE -- installs or upgrades OpenVMS Alpha on the target disk and retains all other contents of the target disk. * NOTE: You cannot use PRESERVE to install OpenVMS Alpha on a disk on which OpenVMS VAX or any other operating system is installed. Do you want to INITIALIZE or to PRESERVE? [PRESERVE]) |
For an upgrade, press the Return key to accept the default (PRESERVE).
7.2.3 Specifying the Target Disk
Next, the procedure asks you for the name of the target disk. If you enter a question mark (?), the system displays a list of devices on your system. Select the appropriate disk and respond to the prompt. For example:
You must enter the device name for the target disk on which OpenVMS Alpha will be installed. Enter device name for target disk: (? for choices) dkb400 |
If you select a device that is not available or that cannot be used for some other reason, the system displays information indicating why the device cannot be used. For example, if you enter MKA500, a tape device, a message similar to the following is displayed:
MKA500 is not a disk device |
The system then prompts you for the volume label and asks if the information is correct. You can accept the default label assigned by the system (AXPVMSSYS) or specify a different volume label (with a limit of 12 characters that can be letters A-Z, numbers 0-9, dollar signs ($), hyphens (-), or underscores (_)).
Compaq strongly recommends that the volume labels for all disks on your system or OpenVMS Cluster have unique labels. If a disk that has the same label as the system disk is mounted, various OpenVMS components will not function as intended. |
After you select the volume label, the target disk is mounted and page and swap files are created. For example:
DKB400: is now labeled ALPHAUPGIV. Do you want to keep this label? (Yes/No) [Yes] OpenVMS Alpha will be upgraded on DKB400:. |
At this point the upgrade performs checks of some related software
products.
7.2.5.1 Spiralog
If your system contains a version of Spiralog lower than Version 1.2,
the following message is displayed:
The target system contains a version of SPIRALOG that is not compatible with this version of the operating system. SPIRALOG must be removed before upgrading OpenVMS Alpha. Termination is strongly recommended. Do you want to terminate? (Yes/No) [YES] |
Note that Spiralog will not work with Compaq OpenVMS Alpha Version
7.3. If you have any version of Spiralog installed on your
system, uninstall it before upgrading to Compaq OpenVMS Alpha Version
7.3.
7.2.5.2 DECamds
Beginning with OpenVMS version 7.2 and DECamds version 7.2, certain parts of DECamds that were previously supplied with the layered product kit are now incorporated into OpenVMS. Because of this, prior versions of DECamds must be removed.
If the upgrade procedure detects a prior version of DECamds, it will display the following message and automatically remove the prior version of DECamds. Note that you must reinstall DECamds if you wish to continue using it.
The target system contains a version of DECamds that is not compatible with this version of the operating system. If you continue DECamds will be removed. A current version of DECamds can be installed after the upgrade completes. |
If PATHWORKS is installed on the system, OpenVMS Version 7.3 requires PATHWORKS Version V6.0D or later. The installation determines the PATHWORKS version and displays one of the following messages if an earlier version of PATHWORKS is present.
If PATHWORKS Version 5 or earlier is present:
PATHWORKS V5 is installed on the target system. This version of PATHWORKS will not work on OpenVMS V7.3. You must upgrade to PATHWORKS V6.0D or later, or disable PATHWORKS on the target system, before upgrading OpenVMS. Please refer to the release notes for additional information. Do you want to continue? (Yes/No) [NO] |
PATHWORKS V6.0-000 is installed on the target system. This version of PATHWORKS is not supported on OpenVMS V7.3. PATHWORKS V6.0D and later are supported on OpenVMS V7.3. You may wish to upgrade to PATHWORKS V6.0D or later before upgrading OpenVMS. Please refer to the release notes for additional information. Do you want to continue? (Yes/No) [NO] |
In both cases the default is to terminate the upgrade. You must explicitly enter Yes and press the Return key to continue.
