Use these procedures to upgrade redundant appliances to SolOS-TR 10.10.1.
These upgrade procedures only apply to the latest version of the Solace PubSub+ appliance. Refer to the version-specific documentation to upgrade to versions before SolOS-TR 10.10.1.
With Guaranteed Messaging
To upgrade SolOS software to SolOS-TR 10.10.1 without a prolonged service outage on a redundant appliance pair that uses guaranteed messaging, follow the procedure in this section.
In the example solace-primary is the primary appliance, and solace-backup is the backup.
Before you begin
Perform the following steps to ensure the redundant pair is in the correct state before upgrading.
-
Review the appliance upgrade notices.
Appliance Upgrade Notices
Before upgrading to version 10.2.0 or later, ensure there are no queue, client-profile, or acl-profile objects configured whose name begins with #telemetry-. As a general rule, no objects should be configured that start with # since Solace uses such object names for internal use.
The following upgrade paths are not supported:
- Direct upgrades from SolOS 9.11.0 or earlier to SolOS 10.9.1 or later.
For unsupported upgrade paths, you must follow the upgrade procedure to the last SolOS-TR version that is part of a supported upgrade path from the source version, before following the upgrade procedure to the destination version.
Upgrades to or from SolOS Early Availability (EA) loads are not supported. All configuration and spooled messages may be lost during the upgrade.
Faulty or noisy serial connections can result in the appliance not booting correctly following an upgrade or restart. Ensure either serial connections are fully functional, or disconnect all serial cables from the Solace appliance prior to upgrading.
Solace recommends upgrading SolAdmin and SolGeneos to the most recent versions before upgrading the appliance to a new major or minor version.
In mixed release replication configurations between this SolOS version and older SolOS versions, config-sync may not work correctly. Running mixed release replication configurations with older SolOS versions is not recommended for extended periods of time. Once the releases are the same, the config-sync issues will clear, so upgrading both replications to the same version should be done as soon as possible. For additional information, contact Solace.
Upgrades that require changing the underlying version of SolBase will not preserve files in the root partition of the appliance’s internal file system.
Configuration changes should not be made while performing any in-service upgrade. This includes avoiding the use of administrative config-sync commands.
Before upgrading standalone appliances that use the Replication feature, follow the Performing a Controlled Failover procedure to fail over to Message VPNs at the alternate replication site.
If the message-spool is enabled as backup but no mate-router-name is configured, the event broker will fail to boot following the upgrade. Prior to upgrading, ensure that either a mate-router-name is configured or the message-spool is not enabled as backup.
The screen output examples shown in this section reflect the software release to which you are upgrading. In the steps that occur before the upgrade, the screen outputs may be formatted differently, or contain slightly different information, depending on the software release from which you are upgrading.
Before upgrading to version 10.9.1 or later, remove any LAG interface that was erroneously configured without a mode of
lacporactive-backup. Such interfaces were always non-functional, however, if they are not removed the event broker will fail to boot following the upgrade.For appliances in Active/Standby redundancy mode, prior to upgrading to version 10.0.1 or later, ensure that the
active-standby-roleis set to eitherprimaryorbackup. If the redundancy role isnoneon either appliance, the upgrade will fail. For appliances in Active/Active redundancy mode, this setting is expected to be set tonone. See Configuring Redundancy Parameters for instructions. -
Ensure that the internal disks are in a redundant state on both the primary and backup appliances.

Before upgrading the appliance, SolAdmin may also need to be upgraded. In addition, after the upgrade, SolGeneos Agent may also need to be upgraded. See Appliance Upgrade Notices for more information.
Procedure
-
Follow all steps in Before you begin. Do not proceed if you cannot confirm that the system is in the correct state.
-
Make a copy of the current SolOS configuration in the
/configssubdirectory on both appliances:solace-primary> enable solace-primary# copy current-config /configs/<old_version>_preUpgradeCfg solace-backup> enable solace-backup# copy current-config /configs/<old_version>_preUpgradeCfg
Where:
<old_version>is the version number of current SolOS software as seen in the output of the show version command. -
On the backup appliance, release activity to the primary appliance:
solace-backup# configure solace-backup(configure)# redundancy solace-backup(configure/redundancy)# release-activity solace-backup(configure/redundancy)# end
-
On the primary appliance, confirm the redundancy status.
If using Active/Active redundancy mode, the Activity Status for both virtual routers should be
Local Active:Example (Output may vary by appliance version):

Shut down the Msg-Backbone service on the primary appliance:
solace-primary# configure solace-primary(configure)# service msg-backbone solace-primary(configure/service/msg-backbone)# shutdown All SMF, WEB, and REST clients will be disconnected. Do you want to continue (y/n)? y solace-primary(configure/service/msg-backbone)# end
-
Upgrade the primary appliance:
solace-primary# boot <new_version>
Where:
<new_version>is the version number of the new SolOS software that was previously copied to the appliance. -
Respond to prompts and then wait for the primary appliance to restart using the new SolOS software. This may take several minutes. You will be disconnected from the CLI and have to reconnect to the appliance.
-
Once reconnected, confirm that the appliance has started using the new software version:
solace-primary> enable solace-primary# show version
-
Start the Msg-Backbone service that was shut down on the primary appliance:
solace-primary#configure
solace-primary(configure)# service msg-backbone
solace-primary(configure/service/msg-backbone)# no shutdown
solace-primary(configure/service/msg-backbone)# end -
Revert activity back to the primary appliance from the backup appliance.
Enter the no release-activity command on the primary appliance to allow activity to return back to it:
solace-primary# configure solace-primary(configure)# redundancy solace-primary(configure/redundancy)# no release-activity solace-primary(configure/redundancy)# end
Enter the redundancy revert-activity Admin command on the backup appliance to administratively force it to give up service:
solace-backup# admin solace-backup(admin)# redundancy revert-activity solace-backup(admin)# end
-
On the backup appliance, release activity to the primary appliance:
solace-backup# configure solace-backup(configure)# redundancy solace-backup(configure/redundancy)# release-activity solace-backup(configure/redundancy)# end
-
Confirm on the primary appliance that it has taken activity for both virtual routers. The Activity Status for both virtual routers should be
Local Active:Example (Output may vary by appliance version):
solace-primary# show redundancy Configuration Status : Enabled Redundancy Status : Down Auto Revert : No Redundancy Mode : Active/Active Mate Router Name : solace-backup ADB Link To Mate : Down ADB Hello To Mate : Down Primary Virtual Router Backup Virtual Router ---------------------- ---------------------- Activity Status Local Active Local Active Routing Interface 1/6/lag1:1 1/6/lag1:2 VRRP VRID 50 197 Routing Interface Status Up Up VRRP Status Master Master VRRP Priority 250 250 Message Spool Status AD-Disabled AD-Disabled Priority Reported By Mate None None
If the primary appliance is not active for both virtual routers, do NOT proceed with the upgrade. Instead, contact Systems technical support for further instructions.

-
Shut down the Msg-Backbone service on the backup appliance:
solace-backup# configure solace-backup(configure)# service msg-backbone solace-backup(configure/service/msg-backbone)# shutdown All SMF, WEB, and REST clients will be disconnected. Do you want to continue (y/n)? y solace-backup(configure/service/msg-backbone)# end
-
Upgrade the backup appliance:
solace-backup# boot <new version>
Where:
<new_version>is the version number of new SolOS software that was previously copied to the appliance. -
Respond to prompts and then wait for the backup appliance to restart using the new SolOS software. This may take several minutes. You will be disconnected from the CLI and have to reconnect to the appliance.
-
Once reconnected to the backup appliance, confirm that the appliance has started using the new software version:
solace-backup> enable solace-backup# show version
-
Start the Msg-Backbone service that was shut down on the backup appliance:
solace-backup# configure solace-backup(configure)# service msg-backbone solace-backup(configure/service/msg-backbone)# no shutdown solace-backup(configure/service/msg-backbone)# end
-
Enter the no release-activity command on the backup appliance to allow activity to return back to it:
solace-backup# configure solace-backup(configure)# redundancy solace-backup(configure/redundancy)# no release-activity solace-backup(configure/redundancy)# end
-
Enter the redundancy revert-activity Admin command on the primary appliance to administratively force it to give up service:
solace-primary# admin solace-primary(admin)# redundancy revert-activity solace-primary(admin)# end
-
On the primary appliance, confirm that the primary appliance is active for the primary virtual router and the backup appliance is active for the backup virtual router. The Activity Status line should read
Local Activefor the primary virtual router andMate Activefor the backup virtual router:Example (Output may vary by appliance version):
solace-primary# show redundancy Configuration Status : Enabled Redundancy Status : Up Auto Revert : No Redundancy Mode : Active/Active Mate Router Name : solace-backup ADB Link To Mate : Down ADB Hello To Mate : Down Primary Virtual Router Backup Virtual Router ---------------------- ---------------------- Activity Status Local Active Mate Active Routing Interface 1/6/lag1:1 1/6/lag1:2 VRRP VRID 50 197 Routing Interface Status Up Up VRRP Status Master Backup VRRP Priority 250 100 Message Spool Status AD-Disabled AD-Disabled Priority Reported By Mate None Active
If the activity status is not correct, do NOT proceed with the upgrade. Instead, contact Solace for further instructions.
-
If the redundancy auto-revert setting was set to not enabled in step 3, enable it on both appliances:
Solace recommends running redundancy with auto-revert not enabled.
solace-primary# configure solace-primary(configure)# redundancy solace-primary(configure/redundancy)# auto-revert solace-primary(configure/redundancy)# end solace-backup# configure solace-backup(configure)# redundancy solace-backup(configure/redundancy)# auto-revert solace-backup(configure/redundancy)# end
-
Ensure that the backup appliance is in the correct redundancy state.
The output from show redundancy on the backup appliance looks like this:
Example (Output may vary by appliance version):
solace-backup# show redundancy Configuration Status : Enabled Redundancy Status : Up Auto Revert : No Redundancy Mode : Active/Active Mate Router Name : solace-primary ADB Link To Mate : Down ADB Hello To Mate : Down Primary Virtual Router Backup Virtual Router ---------------------- ---------------------- Activity Status Local Active Mate Active Routing Interface 1/6/lag1:1 1/6/lag1:2 VRRP VRID 197 50 Routing Interface Status Up Up VRRP Status Master Backup VRRP Priority 250 100 Message Spool Status AD-Disabled AD-Disabled Priority Reported By Mate None Active
The
Auto Revertvalue is a configurable option and may be set toYes, depending on the redundant system configuration.
You have completed this procedure.
