Modifying a tape pool

1. Log in to the group leader as Admin or FabricAdmin.

2. Enter the cryptocfg

--modify -tapepool command followed by a tape pool label or number.

Then specify a new policy, encryption format, or both. The following example changes the

encryption format from Brocade native to DF-compatible.

FabricAdmin:switch> cryptocfg --modify -tapepool -label my_tapepool

-encryption_format DF_compatible

Operation succeeded.

3. Commit the transaction.

FabricAdmin:switch> cryptocfg --commit

Operation succeeded.

Impact of tape pool configuration changes

Tape pool-level policies overrule policy configurations at the LUN level, when no policies are

configured at the tape pool level. The following restrictions apply when modifying tape pool-level

configuration parameters:

• If you change the tape pool policy from encrypt to cleartext or from cleartext to encrypt while

data is 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. This

mechanism prevents the mixing of cleartext data to cipher-text data on the tape.

• You cannot modify the tape pool label or the key lifespan value. If you wish to modify these

tape pool attributes, delete the tape pool and create a new tape pool with a different label and

key lifespan.
