This document provides general information about upgrading WLSE system software to Release 2.12 and provides a pointer to the software images and accompanying Readme files on Cisco.com. The Readme files provide detailed upgrade procedures.
This document contains the following sections:
Other Relevant Documentation
Use this document along with the following documents:
•The Readme files located along with the software images in the download area on Cisco.com.
•The instructions for backing up and restoring the WLSE database in the online help and the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.12.
Please review the following notes and cautions before upgrading.
•WLSE images are subject to import/export regulations respecting strong encryption. Before you are allowed to download the image, you might need to establish a Cisco.com profile or edit your Cisco.com profile to confirm that you are allowed to download such images. You will also need to respond to the Encryption Software Export Distribution Authorization query.
•You cannot upgrade a WLSE 1105 to WLSE 2.12. If you attempt to do so, the installation will fail. Messages in the install.log file will include the following:Error: Hardware type 1105 not supported for this upgrade.Error: Aborting upgrade installation.Daemon Manager could not start. The port is in use.
For information on the install.log file, see Viewing the Installation Log.
•Non-IOS access points are not supported by WLSE 2.12. You must convert all non-IOS access points to IOS before proceeding with the upgrade. For instructions on converting access points, see the following document on Cisco.com:
•Always review the Readme.txt file that accompanies the upgrade image on Cisco.com before attempting to install the upgrade.
•If you are upgrading from Release 2.9 or 2.9.1a, you must first install a patch. (See the Readme for instructions.)
•You can downgrade to an earlier software version by using the recovery CD method. The database is not preserved when you use the recovery CD, so make sure you have a backup from the earlier version before downgrading. For example, if you downgrade from 2.12 to 2.11, you would need to restore a 2.11 backup.
•You cannot upgrade from pre-release, non-FCS, or beta software to the released version. Also, you cannot back up data from pre-release, non-FCS, or beta software and restore it to a WLSE running the released version.
•Upgrading a redundant WLSE cluster requires special procedures. See Upgrading a Redundant Cluster.
There are two basic methods of upgrading a WLSE to 2.12:
•Repository method: Download the upgrade files and install them from a repository. You can use the WLSE itself or a Microsoft Windows server as the repository. This method is easier and faster and is the recommended method.
•Recovery CD method: Download files and create a recovery CD. Then use this CD to upgrade the WLSE.
The database is not preserved when you use this method. You must restore the database after upgrading.
Overview: Repository Method
This section gives an overview of the upgrade procedure for downloading. For details, see the relevant Readme file.
1. Navigate to the software download area on Cisco.com:
Here you will find the Readme files and software images.
2. Read the following image Readme: WLSE-2.12-K9.readme-V1.txt
3. (Strongly recommended) Back up the WLSE database. The upgrade attempts to preserve the WLSE database, but a new backup is needed in case of errors during the upgrade. For information on backing up and restoring the WLSE database, see the online help or the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.12.
4. Install the WLSE 2.12 upgrade image on a repository.
5. Install the upgrade image on the WLSE.
6. If necessary, restore the backup from Step 3.
7. Run a manual inventory on all managed devices. This ensures that radio management functionality will work correctly. For information on running inventories, see the online help or the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.12.
Overview: Recovery CD Method
This section gives an overview of the upgrade procedure for downloading and installing the patch and creating a recovery CD. For details, see the relevant Readme file.
Caution Performing a database backup as described below is essential. Data is not preserved during this method of upgrading, and the database must be restored after upgrading.
1. Navigate to the software download area on Cisco.com:
Here you will find the Readme files and software images.
2. Read the following image Readme: WLSE-2.12-ISO-ReadmeV1.txt
3. Back up the WLSE database. For information on backing up and restoring the WLSE database, see the online help or the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.12.
4. Use the instructions in the ISO Readme file to create the recovery CD.
5. Install the recovery CD.
6. Restore the backup from Step 3.
Upgrading a Redundant Cluster
There are two ways to upgrade software on redundant WLSEs:
Using Manual WLSE Upgrade Procedures
Use the normal WLSE upgrade procedures in the Readme files. This requires that you:
1. Disable redundancy.
2. Upgrade both nodes.
3. Re-enable redundancy.
With this method, the virtual IP addresses are not bound, causing a temporary outage. Also, this might cause issues with connectivity to the remote network.
For information on disabling and re-enabling redundancy, see the online help or the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.12 on Cisco.com.
Using Cisco Works Resource Manager Essentials (RME) Software Image Management (SWIM) and the Redundancy CLI Command
You can use CiscoWorks Resource Manager Essentials (RME) Software Image Management (SWIM) to download the image and then use the redundancy CLI command to accomplish the upgrade.
Note The minimum version required to use this procedure is RME 4.0.2 and Common Services (CS) 3.0 with Service Pack 2.
This method is preferable because:
•You do not have to disable redundancy.
•The virtual IP addresses (VIPs) remain bound to the WLSE systems.
•Connectivity issues with remote networks are avoided.
During this method of upgrading, synchronization between the two servers is briefly halted and restarted; and the WLSE node that was standby before the upgrade becomes the new active node.
Caution Do not change the admin password on either node while the upgrade is in progress or the upgrade will fail on one of the nodes.
The procedure to upgrade by using this method is:
1. Use SWIM to download the image to the local repository on the active node. For details on downloading the image via SWIM, see the CiscoWorks Resource Manager Essentials documentation on Cisco.com at the following URL: http://www.cisco.com/en/US/products/sw/cscowork/ps2073/tsd_products_support_series_home.html, or the CiscoWorks server's online help.
2. Make sure the upgrade image is in the WLSE's local repository.
3. Log in to the WLSE CLI as a the user admin.
4. Run the redundancy upgrade CLI command on either the active or standby node, although it is preferable run the command on the active node. During upgrade, the redundancy status of the node is shown as Active Upgrade or Standby Upgrade.
5. The upgrade proceeds automatically as follows:
a. The standby node is upgraded first.
b. The standby node reboots and becomes active, while the original active node is upgraded.
c. The original active node becomes the standby node.
Software and Hardware that Can Be Upgraded
You can upgrade a WLSE 1030 Express with WLSE 2.11 to WLSE 2.12.
You can upgrade a WLSE 1130 or 1130-19 to WLSE 2.12 as follows:
•From WLSE 2.9 to WLSE 2.12
•From WLSE 2.9.1a to WLSE 2.12
•From WLSE 2.11 to WLSE 2.12
Note If you are upgrading from Release 2.9 or 2.9.1a , you must first install a patch. (See the Readme for instructions.)
WLSE 2.12 software is supported on the WLSE 1030, WLSE 1130, and WLSE 1130-19 hardware. You cannot upgrade a WLSE 1105 to WLSE 2.12. If you attempt to do so, the installation will fail.
Backing Up the WLSE Before Upgrade
Before upgrading WLSE software, back up the database. The upgrade attempts to preserve the WLSE database, but a backup is recommended in case of errors during the upgrade. For information on backing up the WLSE database, see the online help or the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.12.
Caution Backup is essential if you are upgrading via the recovery CD. Data is not preserved during this method of upgrade. After upgrading, you must restore the WLSE's database.
Viewing the Installation Log
The install.log file contains information about files installed during software installation, as well as any errors that occurred. To view install.log and other WLSE system logs, select Administration > Appliance > Status > View Log File.
