Configuration and serviceability considerations for HA RAID configurations

There are configuration and serviceability differences between the primary and secondary controllers.

There are configuration and serviceability differences between the primary controller (that performs direct management of the physical devices) and the secondary controller (that runs as a client of the primary controller). This functional difference requires many of the configuration and serviceability functions to be performed on the primary controller because it is the only controller that can perform the commands.

Attention: Attempting these commands on a secondary controller might return unexpected results.

The following tasks are the common iprconfig tasks that must be performed from the primary controller:

Under the iprconfig menu option titled Work with disk arrays::
- Create a disk array
- Delete a disk array
  Note: On two-system configurations, the usage of the disk array may need to be discontinued from the secondary controller before some actions can be performed from the primary controller such as deleting the array.
- Add a device to a disk array
- Format device for RAID function
- Format device for JBOD function (512)
- Work with hot spares
- Work with asymmetric access
- Force RAID Consistence Check
- Migrate disk array protection
Under the iprconfig menu option titled Work with Disk Unit Recovery::
- Concurrent add device
- Concurrent remove device
- Initialize and format disk
- Rebuild disk unit data
- Force RAID Consistency Check
Under the iprconfig menu option titled Work with disk configuration::
- Change Queue Depth
- Change Format Timeout
Under the iprconfig menu option titled Download microcode::
- Adapter microcode download
- Disk microcode download
- SES device microcode download
