12 Replacing Worker Blades

This chapter describes how to identify and replace a failed Worker Blade in a deployment of Oracle Communications Service Broker Netra 6000 High Availability Manager (HA Manager).

Identifying a Failed Worker Blade

Hardware issues in an HA Manager deployment might cause Worker Blade to fail. The following events might indicate that a Worker Blade has failed:

These events alone do not necessarily mean that a Worker Blade failed. For example, a system administrator might intentionally change the state of a Worker Blade to Powered Off.

To ensure that switching to the Powered Off state or process failure occurred because of a failed Worker Blade, you must check the alarms that the HA Manager generates (see "Managing Alarms" for more details). When a Worker Blade fails, the HA Manager generates a notification, indicating that the OperationalStatus attribute of the hardware MBean which represents the blade, changed from OK to Error.

Replacing a Failed Worker Blade

Replacing a Worker Blade involves the following stages:

  1. Powering off the failed Worker Blade, if necessary

  2. Physical removal of the failed blade and insertion of the new blade

  3. Configuration of the new blade using the Chassis Monitoring Module (CMM) Integrated Lights Out Manager (ILOM) Web interface

  4. Powering on the new Worker Blade

To replace a failed Worker Blade:

  1. If a Worker Blade failed but is still in the Power On state, shut down the failed Worker Blade by performing the steps a through d. Otherwise, proceed to step 2.

    1. In the CMM ILOM Web interface, in the chassis tree, select the failed Worker Blade.

      The System Overview tab appears.

    2. Click the Remote Control tab and then click the Remote Power Control tab.

      The Remote Power Control tab shows the list from which you can select a state to which you want to switch the specified Worker Blade.

    3. From the list, select the Graceful Shutdown and Power Off option.

    4. Click Save.

      The failed Worker Blade is now shutting down.

  2. Remove the failed Worker Blade from the chassis slot.

  3. Insert a new Worker Blade into the same chassis slot.

  4. In the CMM ILOM Web interface, in the chassis tree, select the newly inserted Worker Blade.

    The System Overview tab appears.

  5. Click the Configuration tab and then click the Network tab.

    The Network tab enables you to configure the MAC address and network settings for the new Worker Blade.

  6. Configure the new Worker Blade using the same settings that were used to configure the failed blade.

    Note:

    You must keep a record of the network settings for all Worker Blades. See "Keeping a Record of Network Settings for Worker Blades" for more details.
  7. Click Save.

  8. Click the Remote Control tab and then click the Remote Power Control tab.

    The Remote Power Control tab shows the list from which you can select a state to which you want to switch the new Worker Blade.

  9. From the list, select the Power On option.

  10. Click Save.

    The new Worker Blade is now functional.
