Dell PowerStore – Local discovery fetch error (0xE04040010004)

More Details: Unable to load system configuration data. Contact your service provider for assistance: Service unavailable. Please retry in a few minutes.

So trying again after a few minutes (or even a week) didn’t work. However, this error message appeared immediately after the initial deployment of a “Unified” PowerStore, as soon as you try to login.

After a little research and Feedback by my appreciated Dell colleagues the best solution is to Reimage the PowerStore Appliance. My customer couldn’t access the PowerStore via previously configured IP on the management port, so I stayed on the service port. By default SSH is enabled on the service ports, once your made the initial configuration, so this is the ideal solution when you no longer have access via the management ports. For those who may not be familiar with PowerStore, here is a description of the ports on a PowerStore node:

The Service LAN Port location is shown here with number 5.

If you are in any doubt, pay attention to the arrows in the middle of the two ports (one of the nodes is inverted). Follow the yellow port bearing the tool (service) symbol.

ATTENTION: The system becomes inaccessible to the user over the network if the management cables are removed (this only affects management).

The following configuration is required for the service laptop being used to connect to the service LAN ports:

IP: 128.221.1.249
Mask: 255.255.255.0
Gateway: <none>

The laptop can be physically connected to one of the PowerStore nodes at a time, or to both nodes’ Service LAN ports using a small switch or hub.

However, multiple appliances should never be connected to the same hub or switch as the nodes use the same internal IPs. Never connect multiple appliances to the same hub or switch for Service LAN port access.

Once the laptop IP is configured as shown above and the physical connection is established, you can ping the relevant IPs:

Node A: 128.221.1.250
Node B: 128.221.1.251

To connect to SSH, use your preferred SSH client to connect to the IP addresses shown above over port 22. First, ensure that both nodes are healthy and free of hardware issues.

Run the following command on both nodes and check for any errors or faults. If any failures are detected, they must be addressed before proceeding.

svc_diag list --hardware --sub_options fault_status

The system cannot be reinitialised until both nodes are in service mode.

This requires two commands. The first command sets the service mode flag on the node, and the second command reboots the node into service mode.

svc_rescue_state set

+

svc_node reboot local

# If errors are observed, as mentioned above, the -f (force) flag may be used.

svc_node reboot local -f

The SSH session will close and the nodes will take around 10–15 minutes to reboot. Once rebooted, you can confirm that each node is in service mode by checking for this warning:

[SVC:service@ABC123-B user (*** SERVICE MODE ***)]$

Now login to Node A and reinitialize the system.
In order to start the reinitialization process, run the factory reset command on node A only and follow the command prompt guidance:

svc_factory_reset

# If errors are observed, the --force flag may be used.

Another hardware check is performed

As well as another health check

After the checks, the actual factory reset or reimaging begins.

Wait 70 minutes (1 hour + 10 minutes) while the reimage operation closes the connection.

• All data and configuration settings on the system will be permanently deleted and cannot be recovered once the svc_factory_reset command has been issued and accepted.
• The nodes are then rebooted and returned to a blank factory state.

This process takes around:

• 1 hour for PowerStore T; longer for a downgrade between major versions.
• Do not attempt to do anything before the minimum expected durations listed above have elapsed.

Once reinitialisation is complete, the system can be set up again as if it were brand new. However, if you are still experiencing issues, please contact Dell Support.
