Solution 2253106.1 : How to Restart a PCA Machine After a Power Failure

Applies to:

Private Cloud Appliance X5-2 Hardware - Version All Versions and later
Information in this document applies to any platform.

Goal

To clean up any components that start automatically and bring the PCA rack back to proper working order. These steps are required due to dependencies of components but as total power failures are rare, it shouldn't be a regular process.

Solution

To return the system to proper operation, please follow the steps below:

1. Toggle the power distribution unit (PDU) circuit breakers of both PDUs from the Off to the On position.

There should be 3 switches on each PDU.

2. Wait at least two minutes to allow the PDUs to complete their power-on sequence.

The Ethernet and InfiniBand switches are powered on with the PDUs.

3. Press the Power button on each Fabric Interconnect. Wait until the Status LED stops blinking and is solid green, indicating the system has finished booting.
4. Press the Power button on the storage server heads. Wait approximately two minutes until the power-on self-test completes, and the Power/OK LED on the front panel lights and remains lit.
5. Press the Power button on the management nodes. The management node that completes booting first assumes the master role.
6. When the management nodes are up, press the Power button on each of the compute nodes.

When all compute nodes are up, verify the status of all system components in Oracle VM Manager. If no components are in error state, the appliance is ready to resume normal operation. You can also verify that the ILOMs are up with an IP address by running the following command:

ipmitool sunoem cli "show /SP/network"
