Sun N1 System Manager 1.3 Installation and Configuration Guide

Chapter 3 Upgrading the Sun N1 System Manager Software

This chapter provides the procedure for upgrading your N1 System Manager 1.2 management server to N1 System Manager 1.3. If you are upgrading from Sun N1 System Manager version 1.1 to version 1.3, you must first upgrade your version 1.1 N1 System Manager to version 1.2 as described in Chapter 3, Upgrading the Sun N1 System Manager Software, in Sun N1 System Manager 1.2 Installation and Configuration Guide

The following topics are discussed:

Note –

Security warning: Managed servers on which the Solaris operating system has been deployed by N1 System Manager have a user account named n1gc. The n1gc user account is no longer needed and should be removed as described in Removing the N1 System Manager Version 1.2 n1gc Account.
If you are going to use managed servers with the Grid Engine, and if the OS monitoring or base management features have been enabled for the managed servers, then update the servers for Grid Engine deployment as described in Updating Managed Servers For Use by the Grid Engine

Upgrading to Sun N1 System Manager 1.3

This section provides the procedure for upgrading N1 System Manager 1.2 on the management server to N1 System Manager 1.3.

To Upgrade the Sun N1 System Manager Software

Before You Begin

Back up your N1 System Manager installation as described in Chapter 3, Backing Up and Restoring, in Sun N1 System Manager 1.3 Discovery and Administration Guide.

Steps

Stop all N1 System Manager processes.
- On a Solaris management server, type svcadm disable n1sm
- On a Linux management server, type /etc/init.d/n1sminit stop
Wait for all N1 System Manager processes to stop.

Change directory to the N1 System Manager installation source.

If you are installing from the N1 System Manager DVD, change directory as follows.
- Solaris SPARC-based management server:
  # cd /cdrom/n1_system_mngr/Solaris_sparc/Product/installer
- Solaris x86-based management server:
  # cd /cdrom/n1_system_mngr/Solaris_x86/Product/installer
- Linux x86-based management server:
  # cd /cdrom/n1_system_mngr/Linux_x86/Product/installer
If you are installing from an N1 System Manager installation ISO image, substitute your mount point directory name for /cdrom in the path names.

Type ./install -u to start the upgrade installation process

The Software Evaluation Agreement appears.

Choose whether to accept the agreement and continue installation.

Read the agreement carefully. Type y to continue installation, or type n to exit the installation.

When you continue the upgrade, the upgrade script checks for required Perl modules. When this process completes, the upgrade process then checks the component versions on the management server against the application versions in the N1 System Manager 1.3 installation media. The N1SM Installer upgrade menu then appears, listing which components are up to date, and for which components an upgrade is available.

The appearance of the N1SM Upgrade menu, and the list of components to be upgraded depends on the operating system installed on the management server as shown by the following examples.

Solaris 10 Based Management Server

          N1SM Upgrade (version 1.2 to 1.3 on SunOS)

 1. Install IPMI tool.                            [Up to Date]
 2. Install JDK 1.5.                              [Up To Date]
 3. Install service provisioning components.      [Upgrade Available]
 4. Install OS provisioning components.           [Upgrade Available]
 5. Install user interface components.            [Upgrade Available]
 6. Install service container components.         [Up to Date]
 7. Install N1 System Manager.                    [Upgrade Available]


Non-interactive install in progress

Executing current step:  Install OS packages...

Linux Based Management Server

                N1SM Upgrade (version 1.2 to 1.3 on Linux)

 1. Install IPMI tool.                            [Up To Date]
 2. Install JDK 1.5.                              [Up To Date]
 3. Install Python.                               [Up To Date]
 4. Install service provisioning components.      [Upgrade Available]
 5. Install OS provisioning components.           [Upgrade Available]
 6. Install user interface components.            [Upgrade Available]
 7. Install service container components.         [Up To Date]
 8. Install N1 System Manager.                    [Upgrade Available]


Non-interactive upgrade in progress.

Executing current step:  Install IPMI tool...

The installation process runs each step in sequence. When a step completes successfully, the status of the step is changed to [Up to Date].

If a step fails, you are notified, and the status remains [Upgrade Available] or is changed to [Partially Run]. Exit the installation process and examine the log file /var/tmp/installer.log.latest to determine the cause of the failure. Correct the problem and then run the upgrade process again.

When the upgrade process completes, all running N1 System Manager processes are stopped and restarted, and then you are informed that the N1 System Manager upgrade process is complete.

The installation process then exits. You are prompted to run the n1smconfig utility. N1 System Manager 1.3 provides several new features that must be configured before you restart the N1 System Manager. Run n1smconfig as directed in Configuring the N1 System Manager.

Next Steps

Remove the N1 System Manager Version 1.2 n1gc account as described in the next section.

Removing the N1 System Manager Version 1.2 `n1gc` Account

Managed servers on which the Solaris operating system has been deployed by N1 System Manager have a user account named n1gc. The n1gc user account is no longer needed and should be removed. Removal of the n1gc user account does not affect N1 System Manager 1.3 functionality.

The method used for removal of the n1gc user account depends on whether base management is enabled for the managed server.

If base management is enabled, remove the n1gc user account as follows from. the N1 System Manager command line:
- For a single managed server, type:
  
  start server server command "/usr/sbin/userdel n1gc"
- For a group of managed servers, type:
  
  start group groupip command "/usr/sbin/userdel n1gc"
For information about the base management feature, see Adding and Upgrading Base Management and OS Monitoring Features in Sun N1 System Manager 1.3 Discovery and Administration Guide
If base management is not enabled, refer to your operating system documentation for user account removal procedures.

Updating Managed Servers For Use by the Grid Engine

If you are going to use managed servers on which the OS monitoring or base management features have been enabled, the features must be updated before the managed servers can be used by the Grid Engine.

To update the OS monitoring feature on managed servers:
- For a single managed server, type:
  
  add server server feature osmonitor upgrade=true
- For a group of managed servers, type:
  
  add group group feature osmonitor upgrade=true
To update the base management feature on managed servers:
- For a single managed server, type:
  
  add server server feature basemanagement upgrade=true
- For a group of managed servers, type:
  
  add group group feature basemanagement upgrade=true

For information about the base management and OS monitoring features, see Adding and Upgrading Base Management and OS Monitoring Features in Sun N1 System Manager 1.3 Discovery and Administration Guide
