Decommissioning primary R1 LUNs only
To decommission the primary LUN and make the secondary LUN the primary LUN, complete the
following steps. Failure to do so could result in the LUN state showing as Disabled.
1. Log in as Admin or FabricAdmin.
2. Split the R1/R2 sync.
3. Make the R2 LUN write-enabled.
4. Execute the rekey command on the R2 LUN.
FabricAdmin:switch> cryptocfg --manual_rekey
5. Decommission the primary LUN.
FabricAdmin:switch> cryptocfg --decommission -container
-initiator -LUN
6. Display the decommissioned key IDs.
FabricAdmin:switch> cryptocfg --show –decommissionedkeyids
7. Delete the respective key from the key vault. On the Brocade Encryption Switch, enter the
following command.
FabricAdmin:switch> cryptocfg --delete –decommissionedkeyids
NOTE
Failure to rekey the secondary LUN might result in loss of data on the secondary LUN after the
primary LUN is decommissioned.
Decommissioning mirror R2 LUNs only
To decommission the secondary LUN, complete the following steps:
1. Log in as Admin or FabricAdmin.
2. Split the R1/R2 sync.
3. Make the R2 LUN write-enabled.
4. Decommission the R2 LUN.
FabricAdmin:switch> cryptocfg --decommission -container
-initiator -LUN
NOTE
Do not delete the key from the key vault.
