Controller settings are the settings that apply across one IBM DS5000, IBM
DS4000, or IBM DS3000 system.
You must configure the following settings for
IBM DS5000,
IBM
DS4000, and
IBM DS3000 systems:
- Set the host type for your system to IBM TS SAN VCE.
- Set the system so that both storage systems have the same
worldwide node name (WWNN). See the following website for the scripts that are available to
change the setup for IBM DS5000, IBM
DS4000, and IBM DS3000 systems:

- Ensure that the AVT option is enabled. The host type selection should have already enabled
the AVT option. View the storage system profile data to confirm that you have the AVT option
enabled. This storage profile is presented as a text view in a separate window. See the
following website for the scripts that are available to enable the AVT option:

DS4000, and IBM DS3000 systems:

- write caching
- write cache mirroring
- You must not have caching without batteries enabled.
