NOTE
When changing the tape LUN policy from encrypt to cleartext or from cleartext to encrypt,
or the encryption format from Brocade native to DF-compatible while data is being written
to or read from a tape backup device, the policy change is not enforced until the current
process completes and the tape is unmounted, rewound, or overwritten. Refer to the
section “Impact of tape LUN configuration changes” on page 135 for more information.
c. Commit the configuration.
FabricAdmin:switch>cryptocfg --commit
Operation Succeeded
d. Display the LUN configuration

Modify example
The following is an example of the use of the cryptocfg - - modify command. This example changes
the encryption format from Brocade native to DF-compatible.
FabricAdmin:switch>cryptocfg --modify -LUN my_tape_tgt 0x0
10:00:00:00:c9:2b:c9:3a -encryption-format DF_compatible
Operation Succeeded
