Reclaiming the WWN base of a failed Brocade Encryption Switch

When a Brocade Encryption Switch fails, to reclaim the WWN base, follow these steps:

1. Locate the Brocade Encryption Switch that has failed and deregister from the encryption

group.

cryptocfg –-dereg –membernode <switchWWN>

2. Reclaim the WWN base of the failed Brocade Encryption Switch.

cryptocfg --reclaimWWN –membernode <switchWWN> [-list]

3. Synchronize the crypto configurations across all member nodes.

cryptocfg –-commit

NOTE

When attempting to reclaim a failed Brocade Encryption Switch, do not execute

cryptocfg –-transabort. Doing so will cause subsequent reclaim attempts to fail.

Splitting an encryption group into two encryption groups

In this example, which is represented in Table 15, you have one encryption group with four nodes

from which you want to remove two of the nodes and add them to a new encryption group.

1. Enter the following command on BES1 to reclaim the VI/VT WWN base for BES3:

cryptocfg --reclaimWWN -membernode <BES3-WWN>

When prompted, enter yes.

2. Enter the following command on BES1 to propagate the change to all nodes in the EG:

cryptocfg --commit

3. Enter the following command in BES1 to eject node BES3 from the EG:

cryptocfg --eject -membernode <BES3-WWN>
