General Information

Juniper Netscreen (Screen-OS based products)

Solution: In order for the device to observe the correct DST schedule for 2007 it should be upgraded to one of the following releases before March 11th, 2007:

Release/BranchVersionExpected release date
5.0-ISG-IDP5.0.0-IDP1.r10e or laterDecember 2006
5.0-M2A5.0.0-M2A.r9d or laterNovember 2006

5.25.2.0r3d or laterNovember 2006
5.35.3.0r6 or laterNovember 2006
5.45.4.0r3 or laterJanuary 2007

Juniper SSL-VPN

Solution: The fix for the 2007 DST issue is included in IVE OS 5.3R7 and above.

If you are using the Secure Meeting feature, upgrade to the following software releases which contain the fix for the DST: 5.2R7, 5.3R10 and 5.4R2.1. These are available in the IVE OS Software download page. In order for the IVE to observe the correct DST schedule for 2007, the recommendation is to upgrade to a supported build that reflects the new DST before March 11th, 2007.

Network Appliance (NetApp) Filers

1.0    Updating timezone information on filers

Affected Data ONTAP versions

1.2 Downloading and installing timezone files

1.3 Initializing the new timezone settings

2.0 Updating timezone information on NetCache appliances

2.1 Affected NetCache software versions

2.2 Downloading and installing timezone files

2.3 Initializing the new timezone settings

1.0 Updating timezone information on filers

IMPORTANT: You must complete the steps in sections 1.2 AND 1.3 to update the zoneinfo files on your filer.

Affected Data ONTAP versions

The following software releases contain the most recent zoneinfo files. You do NOT need to update zoneinfo files, if your appliance is running one of the following software releases:

Data ONTAP 7.0.5 (GD) - Fixed Data ONTAP 7.1.1.1 (GA) - Fixed Data ONTAP 7.2.1 (GA) - Fixed For a full list of releases in which this issue is already fixed, see Bug 195805.

1.2 Downloading and installing timezone files

Complete the steps in ONE of the following three methods, based on your site requirements:

  1. Filers that have unrestricted access to the NOW Web site can use Method 1.
2. Method 2 is for customers who would prefer to download the file to a local HTTP server, and then operate the "software install" command without sending an unencrypted username and password through the "software install" command as required in Method 1.

3. Method 3 is for customers who do not have a local HTTP server and whose filers do not have access to the NOW site.

Method 1: Downloading and installing the timezone file using the “software install” command

  1. Enter the following command as a single line:
filer> software install >>http://nowusername:nowpassword@download.netapp.com/download/tools/ontap_timezone/zoneinfo_current/allzones.zip

Note: You must enter your username and password because NOW requires user authentication; replace nowusername and nowpassword with a valid NOW username and password.

2. Proceed to Section 1.3, "Initializing the new timezone settings".

IMPORTANT: You do NOT need to reboot after running the software install command.

Method 2: Downloading to a local HTTP server and installing using the “software install” command

  1. Log in to the NOW site.
2. Save the allzones.zip file to any intermediate location by clicking on the URL shown and choosing “Save as…” or “Save to disk”:

>>http://now.netapp.com/NOW/download/tools/ontap_timezone/zoneinfo_current/allzones.zip

3. Copy the ZIP file to a local HTTP server.

4. At the filer command line, enter the following command:

filer >software install >>http://local_server/allzones.zip

5. Proceed to Section 1.3, "Initializing the new timezone settings".

IMPORTANT: You do NOT need to reboot after running the software install command.

Method 3: Downloading the file to a Windows/UNIX admin host and extracting it onto the filer

From a UNIX admin host with an NFS share of the root volume

Complete the following steps to extract the allzones.tar file from a UNIX admin host to the filer's /etc directory:

  1. Log in to the NOW site.
2. Save the allzones.tar file to your local system (shown as </PATHTOZONEFILE> below by clicking on the URL shown and choosing “Save as…” or “Save to disk”:

>>http://now.netapp.com/NOW/download/tools/ontap_timezone/zoneinfo_current/allzones.tar

3. Enter the following command:

unix> mount <filername:/vol/ROOTVOLUME> /MOUNTPOINT

Note: An “RPC error” at this stage means that the filer does not have its root volume exported. If you get an RPC error, log in as root on the filer and issue the following command:

exportfs –i –o /

Retry the mount command.

4. Enter the following command:

unix> cd </MOUNTPOINT/>etc

5. Enter the following command:

unix> tar xvf </PATHTOZONEFILE>/allzones.tar

6. Enter the following command:

unix> cd /

7. Enter the following command:

unix> umount </MOUNTPOINT>

8. Proceed to Section 1.3, "Initializing the new timezone settings".

From a Windows admin host with a CIFS share of the root volume

Complete the following steps to extract the allzones.zip file into your filer's ETC$ directory:

  1. Log in to the NOW site.
2. Save the allzones.zip file to your local system by clicking on the URL shown and choosing “Save as…” or “Save to disk”:

>>http://now.netapp.com/NOW/download/tools/ontap_timezone/zoneinfo_current/allzones.zip

3. Map the filer's ETC$ share to a network drive, such as T: on the admin host.

Note: T: is used for example purposes only. Use whatever drive letter you have available.

4. Use unzip to extract the allzones.zip file into the T: directory.

5. Proceed to Section 1.3, Initializing the new timezone settings.

1.3 Initializing the new timezone settings

IMPORTANT: You must complete these steps to successfully update your timezone info.

To load the new timezone settings, execute the following commands:

  1. Enter the following command:
filer> timezone

Current time zone is Location/YourTimezone <--- The text in italics will be the entered in the next step.

2. Enter the following command: filer> timezone Location/YourTimezone

Note: The filer does not have to be rebooted to set the timezone rules.

Caution

Do not test this patch on production filers by changing the time forward and back. Manipulating filer time to verify the US DST change triggers Bug 234237. Once you roll the filer back to the current time, scheduled Snapshots will fail. The only way to restore scheduled Snapshot functionality is to reboot the filer.

NetApp engineering has verified that the procedures documented in this article will successfully apply DST settings for 2007.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
