Upgrade Infoblox Code

Below is a brief description / intro on what is involved with upgrading the NIOS image (or the Infoblox Code).

First download the file you want to upgrade to. You have to look through the documentation on the new version to see if the upgrade path is acceptable.

Next, log into the grid (or if not running a grid, the member), GUI (website), not SSH

Click on Grid - Upgrade and take note of the Running Version and Revert Version

Distributing Software Upgrade Files

Distributing the software upgrade files involves unpacking the software files and loading the new software. When you perform a distribution, the NIOS appliance loads the new software code into an alternate disk partition, which overwrites any previously saved version of code that is already there. Therefore starting the distribution disables the appliance from reverting to a release prior to the current version. The time this process takes depends on the number of appliances to which the software is distributed; the more appliances, the longer it takes. Therefore, you might want to schedule the Grid distribution during times when your network is less busy. You can distribute the software immediately or schedule the distribution of any software upgrade file, even if it is not Upgrade Lite compatible.

Distributing Software Immediately

The Grid Master distributes the software upgrade to each member in the Grid, including itself. As an alternative to scheduling the Grid distribution you can distribute the software upgrade throughout the Grid immediately, as follows:

1. From the Grid tab, select the Upgrade tab, and then click Distribute -> Distribute Now from the Toolbar.

2. In the confirmation dialog box, click Yes to start the distribution.

The distribution starts and if there is an active distribution scheduled, the appliance changes its status to inactive. The appliance distributes the upgrade files and displays the status of the distribution in the status bar. You can pause, resume, or stop the distribution by clicking the corresponding icon in the status bar.

Note that starting a manual distribution cancels a scheduled distribution.

Scheduling Distributions

When you schedule a distribution, you schedule the distribution of the Grid Master as well as the upgrade groups, including the Default group. The Grid Master distribution must always occur before the distribution of the upgrade groups.

To schedule a software distribution:

1. From the Grid tab, select the Upgrade tab, and then click Distribute -> Schedule Distribution from the Toolbar.

2. In the Schedule Distribution editor, complete the following:

— Activate Distribution Schedule: Select this to enable the distribution schedule. Clear this if you are creating a distribution schedule you plan to activate at a later date. You can configure and save information in this editor even when you deactivate a scheduled distribution.

— Grid Master Distribution Start Information: Enter a Grid Master distribution date, time, and time zone. The distribution date and time must be before those of the upgrade groups.

—Date: Enter a start date of the Grid Master distribution in YYYY-MM-DD (year-month-day) format. You can click the calendar icon to select a date from the calendar widget.

—Time: Enter a start time of the Grid Master distribution in hh:mm:ss AM/PM (hour:minute:second in AM or PM) format. You can also select a time from the drop-down list.

—Time Zone: Select a time zone that applies to the start time you enter. If this time zone is different from the Grid time zone, the appliance converts the time you enter here based on the Grid time zone, after you save this schedule. When you display this schedule again, it displays the converted time. Selecting the time zone here does not affect any time zone settings in the Grid.

—Admin Local Time: Displays the Grid Master distribution start date and time in the time zone of the administrator

— In the upgrade group table, specify the following for each upgrade group by clicking the corresponding field in each row:

—Start Distribution: Specify when the distribution occurs. Select one of the following from the drop-down list:

•Date/Time: Select this to configure the distribution start date, time, and time zone.

•After : Select After Grid Master to start the distribution immediately after the completion of the Grid Master distribution. Select an upgrade group that must complete its distribution before the group you are configuring. When you select this option, you cannot enter a date, time, and time zone.

Date, Time, and Time Zone are enabled only when you select Date/Time for Start Distribution.

—Date: Enter a distribution start date in YYYY-MM-DD (year-month-day) format. You can click the calendar icon to select a date from the calendar widget.

—Time: Enter a distribution start time in hh:mm:ss AM/PM (hour:minute:second in AM or PM) format. You can select a time from the drop-down list.

—Time Zone: By default, the appliance displays the timezone of the first Grid member in the Upgrade Group. You can change this time zone if you want to enter the time using a different time zone. After you save the schedule though, the appliance converts the time you entered to the time zone of the upgrade group, if it is different. (For information about setting the Grid and member time zones. To change the default timezone of the upgrade group, change the timezone of the first group member

—Admin Local Time: Displays the start date and time in the time zone of the administrator

—Distribute to Members: Indicates whether the distribution with in the group occurs simultaneously or sequentially. You cannot edit this field here. You define this when you create the upgrade group.

3. Save the configuration and click Restart if it appears at the top of the screen. Grid Manager confirms that the schedule is saved and indicates whether the distribution schedule is active. You can click the Refresh icon to refresh the information in this panel.

Note that the appliance does not save the schedule and displays an error message if the schedule contains the following:

— Circular dependencies between upgrade groups. For example, the distribution of Group A is scheduled after Group B, and the distribution of Group B Is scheduled after Group A.

— The distribution time is in the past. Software Distribution Process The following series of events occur after a Grid distribution starts:

• The appliance checks if a NIOS software upgrade was uploaded.

— If the upgrade files are not uploaded, the distribution stops. The appliance displays an error message and if the distribution is scheduled, the appliance deactivates the distribution schedule.

— If the upgrade files are uploaded, the distribution proceeds.

• A single Grid Master uploads the file to a backup partition and unpacks the contents, which overwrites any existing backup software that might have been there. For an HA Grid Master, it is the active node that uploads

the file to a backup partition and unpacks the contents.

— The Grid Master (or active node of the HA Grid Master) sends a command to all nodes that are online to copy their database and software to a backup software partition.

— For an HA Grid Master, the active node sends the command to the passive node as well.

— The nodes perform resynchronization on their backup partition, retrieving only the changed files from the Grid Master.

— After the active node of an HA member receives the software, it then distributes it to the passive node.

When the distribution successfully completes, the appliance updates the distribution status and sets the schedule, if configured, to inactive. The new software is now staged on all member appliances and is ready for use. Grid Manager displays the software version in the Distribution field in the Grid Version Information section.

Managing Distributions

After you start a distribution, you can pause, resume, or stop it.

. Grid Manager displays the status of the overall distribution as well as the status of individual members. You can view this information in the Upgrade tab.

Pausing and Resuming Distributions

The following are some operational guidelines for performing a distribution:

• You cannot create new upgrade groups, add members to a group, or remove members from a group after a distribution starts.

• You can skip a member that is currently offline from a distribution. When both nodes of an HA pair are online, the skip member function is not available.

To pause a distribution:

1. From the Grid Distribution Status bar, click the Pause icon.

2. When the appliance displays a confirmation dialog box, click Yes to pause the distribution.

The Grid Distribution Status bar indicates the distribution is paused.

.

To skip a member from a distribution:

1. From the Grid tab, click the Upgrade tab, and then click Toggle Member List View.

2. Select a member check box, and then click Skip Member from the Toolbar. Grid Manager automatically skips the distribution of software to the members that are offline.

To resume a distribution:

1. From the Grid Distribution Status bar, click the Resume icon.

2. When the appliance displays a dialog box confirming that you want to resume the distribution, click Yes to continue.

Members that have not completed or started distributions that were scheduled at an earlier time resume the distribution.

Stopping Distributions

You can stop a distribution immediately, for example, if there are offline members and you do not want to wait for them to come back online, or if you realize that you have uploaded the wrong software version. When you stop a distribution, you can do the following:

• If the Grid Master has completed its distribution, you can upgrade the Grid immediately. This forces members that do not have a complete distribution to synchronize their releases with the Grid Master.

• If the Grid Master does not have a valid distribution, you can restart the distribution.

• Upload another software upgrade. Ending a distribution does not affect the upgrade schedule, if configured. The Grid upgrade starts as scheduled, as long as the Grid Master completes its distribution.

To stop a distribution:

1. From the Grid Distribution Status bar, click the Stop icon.

2. When the appliance displays a dialog box confirming that you want to stop the distribution, click Yes to continue

Performing Software Upgrades

Performing a software upgrade involves rebooting the appliances and then running the new software. Essentially, each appliance switches between the two software partitions on its system, activating the staged software and saving the previously active software and database as backup.

Note: Before you upgrade the software, Infoblox recommends that you back up the current configuration and database.

Depending on your upgrade paths, you can upgrade to a new release immediately or you can schedule the upgrade.

Before you schedule an upgrade, ensure that you understand the limitations

Upgrading the Grid Immediately

For unschedulable full upgrades, all the Grid members in the Grid must upgrade at the same time. For lite upgrades and schedulable full upgrades or you can upgrade all the Grid members at the same time.

To upgrade a Grid immediately:

•From the Grid tab, select the Upgrade tab, and then click Upgrade -> Upgrade Now from the Toolbar.

Note: The Grid upgrades immediately and if there is an active upgrade schedule, it becomes inactive.
