Managing Satellite Software Upgrade Groups in a Junos Fusion

This topic discusses maintaining satellite software upgrade groups in a Junos Fusion. For more information on the process for creating a satellite software upgrade group, see Configuring Junos Fusion Provider Edge or Configuring or Expanding a Junos Fusion Enterprise.

A satellite software upgrade group is a group of satellite devices that are designated to upgrade to the same satellite software version using the same satellite software package. One Junos Fusion can contain multiple software upgrade groups, and multiple software upgrade groups should be configured in most Junos Fusions to avoid network downtimes during satellite software installations.

When a satellite device is added to a Junos Fusion, the aggregation device checks if the satellite device is using an FPC ID that is included in a satellite software upgrade group. If the satellite device is using an FPC ID that is part of a satellite software upgrade group, the device upgrades its satellite software to the version of software associated with the satellite software upgrade group - unless it is already running the defined version.

When the satellite software package associated with an existing satellite software group is changed, the satellite software for all member satellite devices is upgraded using a throttled upgrade. The throttled upgrade ensures that the aggregation device is not overwhelmed with providing satellite software simultaneously to many satellite devices.

The two most common methods of installing satellite software—autoconverting a device into a satellite device when it is cabled into an aggregation device and manually converting a device that is cabled into an aggregation device into a satellite device—require a configured satellite software upgrade group.

Software upgrade groups are configured and managed from the aggregation device. All satellite devices in a satellite device cluster are part of the same software upgrade group, and a software upgrade group with the name of the satellite device cluster is automatically created when the satellite device cluster is created.

Creating a Satellite Software Upgrade Group

If your satellite device is a member of a satellite device cluster, a satellite software upgrade group with the name of the satellite device cluster is automatically created when the satellite device cluster is created. This satellite software upgrade group must be used to manage the satellite software for all member satellite devices in the satellite device cluster.

For information on creating a satellite software upgrade group for a satellite device that is not part of a satellite device cluster, see Configuring Junos Fusion Provider Edge or Configuring or Expanding a Junos Fusion Enterprise.

Adding Satellite Devices to a Satellite Software Upgrade Group

To add a satellite device to an existing satellite software upgrade group, enter the set chassis satellite-management upgrade-groups upgrade-group-name satellite slot-id-or-range command:

where upgrade-group-name is the name of the existing satellite software upgrade group, and the slot-id-or-range is the FPC slot ID or range of FPC slot IDs of the satellite devices that are being added to the upgrade group.

For example, to add FPC slot IDs 121, 122, and 123 to a satellite software upgrade group named group1:

Additionally, you can use the all statement as your slot-id-or-range to include all satellite devices in the Junos Fusion in the satellite software upgrade group.

For example, to add all satellite devices in the Junos Fusion to a satellite software upgrade group named group1:

Removing a Satellite Device from a Satellite Software Upgrade Group

To remove a satellite device from an existing satellite software upgrade group, enter the delete chassis satellite-management upgrade-groups upgrade-group-name satellite slot-id-or-range statement to delete the statements that initially added the member satellite devices to the satellite software upgrade group.

where upgrade-group-name is the name of the existing satellite software upgrade group, and the slot-id-or-range is the FPC slot ID or range of FPC slot IDs of the satellite devices that are being added to the upgrade group.

In cases where you want to remove some FPC slot IDs that were configured within a range of FPC slot IDs, you might consider re-creating the satellite software group by first deleting it, then re-creating it. To delete the satellite software upgrade group:

You can then re-create the satellite software upgrade group and add satellite devices using the set chassis satellite-management upgrade-groups upgrade-group-name satellite slot-id-or-range statement:

For more information on the satellite software upgrade group creation process, see Configuring Junos Fusion Provider Edge or Configuring or Expanding a Junos Fusion Enterprise.

Modifying the Satellite Software Used by a Satellite Software Upgrade Group

Before you begin:

  • Ensure that a satellite software package is downloaded to the location where you will use it to install the satellite software.

Note:

A satellite software upgrade-group-name can be a user-configured upgrade group or the name of a satellite device cluster.

To associate a satellite software image named satellite-2.0R1.2-signed.tgz that is currently stored in the /var/tmp/ directory from the aggregation device to the upgrade group named group1:

To associate a satellite software package that was previously installed on the aggregation device with a software upgrade group:

For instance:

The satellite software upgrade group is associated with the software package after either of these commands are entered.

Note:

A satellite software upgrade group can be a user-configured upgrade group or the name of a satellite device cluster.

If the group was already associated with a satellite software upgrade group, the previous satellite software package associated with the software group remains the second option for updating satellite software for the satellite software upgrade group. You can disassociate any satellite software package from a satellite software upgrade group using the instructions in the next section.

To associate a new satellite software image with the software upgrade group:

Deleting Associated Satellite Software from a Satellite Software Upgrade Group

This section describes how to delete a satellite software package association from a satellite software upgrade group.

This procedure is always optional. You can always update the satellite software associated with a satellite software upgrade group using the procedure in the previous section, without deleting the satellite software from the satellite software upgrade group.

When a new satellite software package is associated with a satellite software upgrade, the previous satellite software package remains associated with the upgrade group as a backup option. The satellite software upgrade group can be associated with up to two satellite software packages, so no other satellite software packages can be associated with the satellite software upgrade group.

This process disassociates the specified satellite software package from the list of potential packages used by a satellite software upgrade group. It is useful for maintenance purposes only, like if you wanted to ensure a satellite software upgrade group was never associated with a specific satellite software package.

To disassociate a satellite software image from a satellite software upgrade group:

where the upgrade-group-name is the name of the upgrade group that was assigned by the user.

For example, to delete the current satellite software image association to the upgrade group named group1:

Deleting Satellite Software on the Aggregation Device

This section describes how to remove a satellite software package from a Junos Fusion system. This will remove the software from the aggregation device as well as any association with any satellite software upgrade groups. This should be done when another satellite software version is available and will free up the space occupied by the software being removed.

Note:

We recommend deleting satellite software that is not in use to free up space on a QFX10000 acting as an aggregation device.
