Controller settings for IBM DS5000, IBM DS4000, and IBM DS3000 systems
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:
- You must have the following options enabled on any logical units that are mapped to IBM
DS5000, IBM
DS4000, and IBM DS3000 systems:
- read caching
- write caching
- write cache mirroring
- You must not have caching without batteries enabled.
- Configuration settings for IBM DS5000, IBM DS4000, and IBM DS3000 systems
The system configuration interface provides configuration settings and options that can be used with the system. - Global settings for IBM DS5000, IBM DS4000, or IBM DS3000 systems
Global settings apply across IBM DS5000, IBM DS4000, or IBM DS3000 systems. - Logical unit settings for IBM DS5000, IBM DS4000, and IBM DS3000 systems
Logical unit (LU) settings are configurable at the LU level. - Miscellaneous settings for IBM DS5000, IBM DS4000, or IBM DS3000 systems
The system supports all of the media scan settings that are provided by a IBM DS5000, IBM DS4000, or IBM DS3000 system. Set the background media scan to enabled and set the frequency to 30 days. These settings are enabled at both the system level and the individual logical drive level.
