To minimize the impact of Grid upgrades on your system operations, you can organize members into upgrade groups and schedule their software distributions. This is useful, for example, in a large Grid spanning multiple time zones where there are fluctuating network and downtime considerations at various locations. Note that you can also schedule their upgrades, depending on the existing releases and their upgrade paths. For information about the different upgrade methods, see Lite Upgrades and Full Upgrades
You can also import and export upgrade groups and their schedules in CSV format. For more information, seeInfoblox CSV Import Reference.
Infoblox provides two default upgrade groups:

• Grid Master: After you configure the Grid Master, it automatically becomes the only member of this group. You cannot modify or delete this group.

• Reporting Member: After you configure a reporting member in a Grid, it automatically becomes the only member of this group. This group will be upgraded automatically after the Grid Master and before other upgrade groups. You cannot modify, delete, or schedule this upgrade group. For information about reporting, seeInfoblox Reporting and Analytics.

• Default: This is the default upgrade group to which the appliance automatically assigns Grid members. If you do not explicitly assign a member to an upgrade group, it remains in the Default group. You cannot delete or rename this group.

  Make sure that the default group has at least one member associated with it, otherwise the appliance displays that the upgrade process is still in progress even though it is complete. To avoid this, you can either use the Infoblox > set grid_upgrade forced_end command to stop the upgrade process or keep at least one member in the default group. For more information, see set grid_upgrade.

Grid Manager provides information about the upgrade group to which a member belongs. You can add or delete an upgrade group and monitor the software version that is currently running on the Grid and on individual member. You can do the following:

...

1. From the Grid tab, select the Upgrade tab.

2. Click Toggle Group List View to display the list of upgrade groups, and then click the Add icon.

3. In the Add Upgrade Group wizard, complete the following:

   • Name: Enter a name for the upgrade group. The name can contain alphanumeric characters, spaces, underscores, hyphens, and dashes.

   • Distribute to Members: Select one of the following to specify how the Grid Master distributes software to the members in the group.

     • Simultaneously: Select this to distribute software upgrade files to all group members at the same time.

     • Sequentially: Select this to distribute software upgrade files to group members in the order they are listed in the group members list.

   • Upgrade Members: Select one of the following to specify how the group members upgrade to the new software version.

     • Simultaneously: Select this to upgrade all group members at the same time.

     • Sequentially: Select this to upgrade group members in the order they are listed in the group members list.

   • Comment: Enter useful information about the upgrade group, such as the location of the group.

4. Click Next to select members for the group. Complete the following:

   • Click the Add icon. Grid Manager adds a row to the Member Assignment table.

   • Click Select. In the Member Selector dialog box, select the members you want to add to the group, and then click the Select icon. Use Shift+click and Ctrl+click to select multiple members. Note that if you choose to distribute and upgrade members sequentially, the distribution and upgrade occur in the order the members are listed. You can reorder the list by dragging a member to a desired location or by selecting a member and using the up and down arrows next to the checkbox to place the member at a desired location. You can also delete a member from the list.

     After you add a member, the appliance adds it to the group members list. The first Grid member in the list determines the time zone of the group when you schedule the distribution and upgrade. Therefore, Grid Manager displays the time zone of the first Grid member in the list. (For information about setting time zones, see Managing   Time   Settings.)

5. Save the configuration and click Restart if it appears at the top of the screen.

...

In the Upgrade tab, Grid Manager lists the Grid Master group, the Default group, and other upgrade groups you have configured. You cannot modify or delete the Grid Master group. You can modify the Default group, but you cannot delete it. To view the members in a specific upgrade group, click the arrow next to the group name to expand the group. All groups are collapsed by default.
Before a distribution or upgrade starts, you can move members from one group to another, reorder the members, or remove a member from an upgrade group. The member you remove automatically joins the Default group. (For information, see Managing Distributions, in Upgrading NIOS SoftwareSoftware.) You cannot add, delete, or reorder members in an upgrade group while a distribution or upgrade is in progress. You can skip a member in an upgrade group from a distribution only before the distribution starts, or after you pause it. For information, see Pausing and Resuming Distributions in Upgrading NIOS Software.
To view the upgrade groups in a Grid:

...

You can hide some of the default columns, but you cannot sort the information in this table. You can use filters and the Go to function to narrow down the list. With the autocomplete feature, you can just enter the first few characters of an object name in the Go to field and select the object from the possible matches. You can also create a quick filter to save frequently used filter criteria. For information, see Using Quick Filters, in Finding and Restoring Data.

Deleting Upgrade Groups

When you delete an upgrade group, members in the upgrade group that you want to delete will be moved to the Default group. Grid Manager displays a warning before deleting an upgrade group.
To delete an upgrade group:
