2. Verify that the power source matches the power cord feature code for the
storage system. The power connector type for the current model can differ from
the previous model. For more information, see “Feature codes for power cords”
on page 110.
3. Verify that the circuit breaker rating meets the storage system requirements.
DS8880 power requirements are completely different from the DS8870
requirements. For more information, see “Input voltage requirements” on page
157
4. Verify that the physical requirements necessary for storage system installation
are sufficient.
The location, floor type, frame weight, and cable management must be
considered.
5. Verify that you have a complete list of the necessary licensed function keys.
The list of licensed function keys must match that of the converted model. The
keys are used to reactivate all licensed functions after completion of the model
conversion.
Removing data, configuration, and encryption
You must migrate all data from the existing storage system, remove the logical
configuration and remove the encryption group before the technical service
representative can begin the model conversion.
Procedure
Ensure that the following operations are completed on the storage system that is to
be converted before the technical service representative arrives:
1. Migrate all data from the storage system.
2. Remove the logical configuration from the storage system.
3. Remove the encryption group, recovery keys, Security Key Lifecycle Manager,
and Tivoli Key Lifecycle Manager server information from the storage system.
4. If data must be securely removed from the management console and processor
drives, you can request the technical service representative to perform a Secure
Data Overwrite (SDO). This is an extra service. The SDO must be performed
after you have migrated data and removed the logical configuration and
encryption group, and before you begin the conversion. An SDO can take
significant time to complete. You must plan accordingly.
Completing post-conversion tasks
After the model conversion is completed by an IBM service representative, a few
more tasks must be completed.
Procedure
Complete the following tasks on the DS8880:
1. Download the necessary licensed-machine-code keys from the IBM Data storage
feature activation (DSFA) website (www.ibm.com/storage/dsfa) by using the
same frame serial number as the storage system that was converted.
2. Apply the licensed-machine-code keys obtained from the IBM DSFA website.
3.
If encryption is to be activated:
a. Assign the Security Key Lifecycle Manager servers.
b. Create the encryption recovery keys to prevent encryption deadlock.
