Disaster Recovery Sequence for SME Tape
Caution |
Use this procedure only if the SME cluster cannot be recovered to an online / active state. A new SME Cluster must be created and existing keys imported into the new SME Cluster. |
To recover SME tape, follow these steps:
Procedure
Step 1 |
Ensure that all backup operations are stopped. |
Step 2 |
If the ASCII configuration of the SME Cluster exists on the switches, you must removed it. Save the show SME tech support and show running config commands off the switches before any changes are done. These files are useful when configuring the new SME Cluster. |
Step 3 |
Log in to the Key Manager (DCNM Web Client) with credentials that allow you to do key operations (admin, sme-kmc-admin, network-operator). |
Step 4 |
Export all volume groups from the original cluster. If you already have an up to date exported backup, you can skip this step. The Master Key of the old SME Cluster is required to complete this step. If the Cluster’s security mode is Basic, you must have the Master Key file. If the Cluster’s security mode is Standard or Advanced, you must supply the required number of smart cards to reconstitute the Master Key.

Step 5 |
Using the DCNM UI, create a new cluster with a new name, with the same cluster settings. |
Step 6 |
Create a new tape group to match each old tape group.
|
Step 7 |
If you want to continue writing to existing tapes, modify smeserver.properties in the FMS conf directory. If you skip this step, the existing tapes will be read only.
|
Step 8 |
Import the volume groups from step 3 into the new cluster in their respective tape groups volume groups. |
Step 9 |
If you did not skip step 7, complete these steps: |
