The system recovery procedure works
only when all node canisters are in candidate status. Ensure that
the service assistant displays all of the node canisters with the
550 error code. The 550 error code is the expected node error when
more than half of the nodes in the system are missing or when the
active quorum disk cannot be found. If the service assistant displays
any node canisters with error codes 550 or 578 and all the recommended
actions have been completed on these nodes, you must remove their
system data.
Before performing this task, ensure that you have read the introductory information in the
overall recover system procedure.
Having used the service assistant to identify the system status and specific error, you will
continue to use the service assistant to complete this procedure.
Selecting Change Node in the service assistant tool lists all of the Spectrum Virtualize nodes
that have logged in to the node that is running the tool. Follow these guidelines when
performing the recovery procedure:
- The system column of the node table identifies any nodes that are not in the system
of nodes that must be recovered. Do not remove the system data for these nodes.
- Do not remove system information from any node that has online status, unless directed to
do so by remote technical support.
- Do not remove the system data from the first node until you ensure that the following
conditions are met:
- All nodes in the system of nodes are listed in the Change Node part of the service
assistant and are in service status with error 550 or 578
- You have checked the extra node error data for each node to ensure that no other
communication or hardware problem is causing the node error.
- In the change node part of the service assistant tool, select the radio button of the node
with status service and error 550 or 578.
- Select Manage System.
- Click Remove System Data.
- Confirm that you want to remove the
system data when prompted.
- Remove the system data for the other nodes
that display a 550 or a 578 error.
All nodes
previously in this system must have a node status of Candidate and have no errors listed against them.
- Resolve any hardware errors until the
error condition for all nodes in the system is None.
- Ensure that all nodes in the system of nodes
to be recovered display a status of candidate.
When all nodes display a status of candidate and all error conditions are
None, you can run the system recovery procedure.
