The procedure for recovering a failed StorageGRID appliance Storage Node is the same whether you are recovering from the loss of the system drive or from the loss of storage volumes only.
|
If more than one Storage Node has failed (or is offline), contact technical support. Don't perform the following recovery procedure. Data loss could occur. |
|
|
If this is the second Storage Node failure in less than 15 days after a Storage Node failure or recovery, contact technical support. Rebuilding Cassandra on two or more Storage Nodes within 15 days can result in data loss. |
|
If more than one Storage Node at a site has failed, a site recovery procedure might be required. See How technical support recovers a site. |

|
If ILM rules are configured to store only one replicated copy and the copy exists on a storage volume that has failed, you will not be able to recover the object. |

For hardware maintenance procedures, such as instructions for replacing a controller or reinstalling SANtricity OS, see the maintenance instructions for your storage appliance. |
