Before Upgrading to Version 1.3(3)

You can upgrade directly to GSS software version 1.3(3) from GSS software versions: 1.3(x), 1.2(1.0.3), 1.2(1.1.2), 1.2(2.0.3), 1.2(2.1.3), and 1.2(2.2.0). To upgrade from GSS software version 1.1(x), you must first upgrade to GSS software version 1.2(2.2.0).


Note If you upgrade from GSS software version 1.1(x) to 1.2(2.2.0) to 1.3(3), do not change the role of the GSS devices in the network until you have completed the installation on each GSS device in the network.


Before you upgrade to software version 1.3(3), be sure that you:

1. Determine if you need to perform the steps to remove double quotes from names and associated description strings. GSS software versions 1.3(x) do not allow the use of double quotes for names and associated description strings. If you are upgrading from a software version earlier than version 1.3(1) and you have instances of double quotes (") in object names or associated descriptions, you must remove all double quotes before you upgrade to software version 1.3(3). Follow the steps in the "Removing Double Quotes from Object or Description Names"section.

2. Perform a full backup of your primary GSSM database using the links provided in the "Backing Up Your Current Primary GSSM Database" section.

Removing Double Quotes from Object or Description Names

GSS software versions 1.3(x) do not allow the use of double quotes for names and associated description strings. If you have any instances of double quotes (") in object names or associated descriptions (for example, "dns rule 01" or "dns rule 02), you must remove all double quotes before you upgrade to software version 1.3(3).

Perform these steps to remove double quotes:

1. If you are upgrading from:

Version 1.1(x) to version 1.3.3, first upgrade to GSS software version 1.2(2.2.0), then proceed to step 2.

Version 1.2(x) or 1.3(x), go to step 2.

2. Perform a full backup of your primary GSSM database. For details on performing a full backup, refer to Chapter 7, Backing Up, Restoring, and Downgrading the GSSM, the "Backing Up the Primary GSSM" section in the Cisco Global Site Selector Administration Guide. Provide a unique name for the backup file (this is the backup file that includes double quotes). If you need to downgrade in the future, you can use this file to restore your unmodified 1.2 or 1.3(x) database.

3. In GSS software version 1.2 or 1.3(x), access the GUI at the primary GSSM. Locate and remove the double quotes from any object names or associated descriptions.

4. Perform a full backup of your modified primary GSSM database. Provide a unique name for the modified backup file. If you need to downgrade in the future, you can use this file to restore your modified 1.2 or 1.3(x) database.

5. Upgrade to GSS software version 1.3(3) as described in the Cisco Global Site Selector Administration Guide, Appendix A, Upgrading the GSS Software.

Backing Up Your Current Primary GSSM Database

Before you upgrade, you must back up your current primary GSSM database in the event that you need to restore. Refer to the appropriate instructions for backing up your version of GSS software:

For software version 1.3(3), refer to Chapter 7, Backing Up, Restoring, and Downgrading the GSSM, the "Backing Up the Primary GSSM" section in the Cisco Global Site Selector Administration Guide. Also, review the software version 1.3(3) software upgrade sequence as described in the Cisco Global Site Selector Administration Guide, Appendix A, Upgrading the GSS Software.

For software version 1.2, refer to Chapter 7, Backing Up and Restoring the GSSM, the "Backing Up the Primary GSSM" section in the Cisco Global Site Selector Administration Guide.

For software version 1.1, refer to Chapter 9, GSS Administration and Troubleshooting, the "Backing Up the GSSM" section in the Cisco Global Site Selector Configuration Guide.

For software version 1.0, refer to Chapter 3, GSS Administration and Troubleshooting, the "Backing Up the GSSM" section in the Cisco Global Site Selector Configuration Guide.

Downgrading from Version 1.3(3)

Downgrading from software version 1.3(3) to 1.3(2) on GSS devices 4480, 4490, 4491, 4492 is supported.

This procedure applies to downgrading from software version 1.3.3 to versions earlier than 1.3(2) only on GSS 4490 and 4491 devices. If your GSS system uses 4480 devices, you will need to make RMA arrangements to return the devices to Cisco for the downgrade.

Follow the steps in this procedure if you need to downgrade from software version 1.3(3) to versions earlier than 1.3(2). If you have any questions about the need to downgrade your system, contact Cisco Technical Assistance Center (TAC). See "Obtaining Technical Assistance" for more information. To restore an earlier version of your software, you must have a previous backup of the primary GSSM database that corresponds to the version to which you wish to restore. For example, if you wish to downgrade to software release 1.2(2.2.0), you must have a software release 1.2(2.2.0) database backup that you can restore. A 1.3(3) database cannot run on the earlier software platforms because of changes in the database schema and kernel.

In addition to your earlier GSS software version backup, downgrading requires that you download a recovery image from cisco.com, then create a Recovery CD for the software version to which you need to downgrade.

You need the following items to complete the downgrade:

Full backup of your primary GSSM database that corresponds to the software version to which you wish to restore. This backup is required to restore the database on the primary GSSM.

Recovery CD.

Keyboard, mouse, and monitor.

Downgrading the GSS devices in your system requires that you complete the following procedures:

Obtaining the Recovery Image and Creating the Recovery CD

Using the Recovery CD to Downgrade GSS Devices

Restoring a Primary GSSM Database

Obtaining the Recovery Image and Creating the Recovery CD

The steps in this section describe how to obtain the recovery image from Cisco Systems and create the Recovery CD. If necessary, contact Cisco Technical Assistance Center (TAC) for more information about obtaining the recovery image.

Refer to the steps described in Chapter 7, Backing Up, Restoring, and Downgrading the GSSM, the "Restoring Your Primary GSSM from a Previous Backup" section in the Cisco Global Site Selector Administration Guide.

Additional Information on GSS Front Panel Buttons and LEDs

The following information augments the material on the GSS front panel features provided in Chapter 1, Introduction, in the Cisco Global Site Selector 4491 Hardware Installation Guide.

The System ID button on the GSS front panel allows you to identify the GSS when it is installed in a single rack with multiple GSS devices. The LED illuminates on the rear panel of the active GSS.

Press the front System ID button to activate the blue LED on the rear panel of the GSS.

Press the rear System ID button to turn off the LED on the rear panel.

Note that the Power Spike (or Surge) indicator LED operates as the System ID button on the front of the GSS. Thus, if you press the System ID button on the front or rear of the GSS, the rear System ID button will blink as well as the Power Spike indicator LED on the front of the unit. The reason for this is that the System ID button does not activate a corresponding LED, so it uses the Power Spike indicator LED instead.

If there are several GSSs in the rack and you press the System ID button, you can locate the GSS you are working on should you need to go to the rear of the rack. After using the System ID button to identify the GSS, it is recommended that you press the button a second time to restore solid LED status and thus, re-enable the Power Spike indicator. It is also recommended that you only press the System ID button during installation or troubleshooting in order to retain the Power Spike detection and reporting feature.

Operating Considerations for Software Version 1.3(3)

The following operating considerations apply to software version 1.3(3):

When you use a TCP keepalive with the fast detection and graceful termination methods to test a Telnet service on a server running Windows Server 2003, port 23 may fluctuate between the Up and Down state (port flapping). If port flapping occurs on TCP port 23 of Windows Server 2003, you will notice an increase in keepalive negative probe and keepalive transition counts on the Answer Keepalive Statistics list page of the primary GSSM GUI. To resolve this issue, increase the retries value for the TCP keepalive. A retry value of three or four should prevent flapping on port 23 when connecting to a server running Windows Server 2003.

Depending on the number of TCP keepalives you require to send from port 23 to servers running Windows Server 2003, specify the retries value as follows:

If the GSS is transmitting numerous TCP keepalives using port 23, globally change the Number of Retries value for all TCP keepalives on the Configure Global KeepAlive Properties details page of the GUI. If you are using the keepalive-properties tcp fast command in the CLI to configure keepalives, change the value of the retries option.

If TCP keepalives are being used for different devices or ports, change the Number of Retries value on a per TCP keepalive basis using the Modifying Answer detail page of the GUI. If you are using the keepalive type tcp command in the CLI to configure keepalives on a per TCP keepalive basis, change the value of the retries option.

Cisco LocalDirector does not reply properly to TCP keepalives sent on port 23 from a GSS device. To resolve this behavior, specify a different keepalive method with LocalDirector or directly probe the servers located behind LocalDirector.

For a GSS to successfully operate and perform DNS resolutions, a name server must be properly configured, running, and reachable by the GSS.

When a primary GSSM has been upgraded to software version 1.3(3), but other GSS devices remain at version 1.2(1.1.2) or 1.2(2.0.3), global server load-balancing configuration settings are not propagated to the GSS devices still at version 1.2(1.1.2) or 1.2(2.0.3). To avoid this behavior, ensure that all GSS devices on the network are upgraded to software version 1.3(3) before you configure global server load balancing.

GUI Change in Software Version 1.3(3)

The GUI on the primary GSSM now displays the load for each answer, as well as the answer status, either online or offline, on the Monitoring > Answer Status details page. Previously, only the answer status was shown.

In some cases, the KAL-AP load may be less than 255, yet the answer status remains offline. If so, some other keepalive is causing the answer to be offline.

Software Version 1.3(3) Open Caveats, Resolved Caveats, and Command Changes

The following sections contain the open caveats, resolved caveats, and command changes in software version1.3(3):

Software Version 1.3(3) Open Caveats

Software Version 1.3(3) Resolved Caveats

CLI Command Changes in Software Version 1.3(3)

Software Version 1.3(3) Open Caveats

This section lists the open caveats for software version 1.3(3).

CSCse79659—DNS query processing is case sensitive, but should be not be case sensitive. For example, when a domain is configured as .*foo\.com\.au, the GSS only matches all lowercase characters. The following variations of the domain name example shows names on which the GSS will not match:

*.FOO.COM.AU - is not matched

*.foo.com.AU - is not matched

Workaround: Define a regular expression of the form: .*[fF][oO][oO]\.[cC][oO][mM]\.[aA][uU]

CSCsf17052—The GSS 4492 interface link does not come up when speed/duplex are hard set. When a GSS is connected to a Catalyst 6500 and both devices are hard set to 1000/full, the Ethernet link will not come up. If you set the GSS to auto speed/duplex, the link will come up. The link stays up if you set it back to 1000/full. Workaround: Set both devices to auto-negotiate.

Software Version 1.3(3) Resolved Caveats

This section lists the resolved caveats for software version 1.3(3).

CSCse14107—You cannot use the console when AAA accounting is enabled. When you issue aaa accounting commands on the GSS, you are logged out of the primary GSSM. If you repeat the login attempt, the login succeeds. If you execute any command, you are logged out. Workaround: Access the GSS IP address using telnet or SSH. Do not access the GSS IP address using the console port.

CSCse78532—When doing Name Server Forwarding on the GSS, client initiated traffic to the GSS coming in as TCP (zone transfers or large requests) is incorrectly forwarded to the DNS server as a UDP request.

CSCse41672—GSS primary and standby database timestamps are not synchronized.

CSCsd27446—The GSS WebGUI Monitoring tab shows zero keepalive probes per second even when there are probes present. Workaround: Manually compute the keepalive probes per second based on the configuration and the show command outputs.

CSCsc71389—A DNS rule using hash has an uneven load distribution. When you configure a DNS rule with the hashed load distribution method and the associated answer group only contains two answers, a 2:1 distribution of load occurs.

CSCse33535—Generating a tech report results in a Java null pointer exception in CrDirector.

CSCsf09042—The GSS becomes unusable when you to attempt to restore the startup config from the disk. Workaround: Ensure there is a database on the GSS before attempting to copy the startup config.

CSCse94530—Changes to the GSLB configuration may not take effect after performing a role swap. During and after a role swap in a GSS network, configuration changes on the primary GSSM are displayed by the show gslb-config command, but statistics relating to the new config are not compatible with the changed configuration.

CSCse94715—With remote SSH TACACS authentication, you no longer need to manually create a local user for a successful authentication.

CLI Command Changes in Software Version 1.3(3)

Table 1 lists the new clock command options in software version 1.3(3). Table 2 lists the command that was removed from software version 1.3(3).

Table 1 New CLI Clock Command Options in Software Version 1.3(3) 

Command and Syntax
Description

clock

The user-summer-time, user-timezone, and summer-time options have been added to the clock command to allow you to set:

user-defined daylight savings time

user-defined timezones

daylight savings time to another predefined summer time

The syntax for the new clock command options is as follows:

clock [user-summer-time summer-time name | start time (hh:mm) <0-23> |
start day <Friday, Monday, Saturday, Sunday, Thursday, Tuesday, Wednesday> |
start week
<1-5> | start month <April, August, December, February, January, July, June, March, May, November, October, September>| end time (hh:mm) <0-23> |
end day <Friday, Monday, Saturday, Sunday, Thursday, Tuesday, Wednesday> | end week <1-5> | end month <April, August, December, February, January, July, June, March, May, November, October, September> | offset (in minutes) <0-1440>]

[user-timezone timezone name | hour_offset <-23,+24> | minute_offset <0-59>]

[summer-time timezone <ADT (Atlantic Daylight Time) | AKDT (Alaska Standard Daylight Time) | CDT (Central Daylight Time) | EDT (Eastern Daylight Time) | MDT (Mountain Daylight Time) | PDT (Pacific Daylight Time)]

The options and variables for this command are:

user-summer-time (Optional) Allows you to specify entries such as a summer-time name, start time, start day, start week, start month, end time, end day, end week, end month and an offset for daylight savings time.

user-timezone (Optional) Allows you to specify entries such as a timezone name and an hour and minute offset for a timezone.

summer-time (Optional) Allows you to directly set daylight savings time to some predefined summer times.

clock (continued)

For example, if you wish to set up standard time and daylight savings time in the Eastern Time Zone (i.e., Eastern Standard Time (EST) Universal Time Coordinated (UTC -5)) and its daylight saving time (i.e., Eastern Daylight Time (EDT) (UTC -4), you follow these instructions. EDT begins here at 2:00 am local time on the first Sunday in April and ends at 2:00 am local time on the last Sunday of October.

The following procedure shows how to set the time zones using the 3 new clock command options:

1. Set the clock based on UTC.

gss2.gss-tb6.com#clock set 7:45:00 September 7 2006 
gss2.gss-tb6.com#show clock 
System time: Thu Sep  7 07:45:05 UTC 2006

2. Set the clock to EST by using the user-timezone command option.

Timezone set.com#clock user-timezone EST -5 0 
Please restart the GSS (reload) to sync log timestamps to new timezone. 
gss2.gss-tb6.com#show clock                   
System time: Thu Sep  7 02:45:17 EST 2006

Note that you need to set the user-timezone before using the summer-time command option.

3. Set the summer-time on the GSS in one of two ways:

a. Enter the summer-time command option.

gss1.gss-tb6.com#clock summer-time ?
  ADT   Atlantic Daylight Time: 2 am 1st Sunday April - 2 am last Sunday Oct, +60 
min
  AKDT  Alaska Standard Daylight Time: 2 am 1st Sunday April - 2 am last Sunday 
Oct, +60 min
  CDT   Central Daylight Time: 2 am 1st Sunday April - 2 am last Sunday Oct, +60 min
  EDT   Eastern Daylight Time: 2 am 1st Sunday April - 2 am last Sunday Oct
  MDT   Mountain Daylight Time: 2 am 1st Sunday April - 2 am last Sunday Oct, +60 
min
  PDT   Pacific Daylight Time: 2 am 1st Sunday April - 2 am last Sunday Oct, +60 min
gss1.gss-tb6.com#clock summer-time EDT 
Timezone set.
Please restart the GSS (reload) to sync log timestamps to new timezone. 

b. Enter the user-summer-time command option.

gss2.gss-tb6.com#clock user-summer-time EDT 2:00 Sunday 1 April 2:00 Sunday 5 
October 60  
Timezone set. 
Please restart the GSS (reload) to sync log timestamps to new timezone. 
gss2.gss-tb6.com#show clock 
System time: Thu Sep  7 03:47:07 EDT 2006

If you reside in one of the following timezones, ADT, AKDT, CDT, EDT, MDT, or PDT, you use the summer-time option as shown in step 3a to set the summer-time on the GSS. If you need to configure a custom summer-time, use the user-summer-time option and follow step 3b instead. Note that in this procedure, the summer-times are predefined summer times.

After the procedure is finished, the clock will be set back to the user-timezone after the daylight savings time duration is covered. In this particular instance, the timezone will be set back to EST after 2:00 A.M on the last Sunday in October.

You set both the summer-time and user-summer-time command options with respect to UTC only, and not the user-timezone. Also, there is no relation to the clock timezone command that was used to establish a timezone on the GSS.
