Quick check for Command Devices mapped from Hitachi arrays

In CCI, under HORCM/etc run:

raidscan -x findcmddev 0-100

If Tuning Manager Agents are installed:


In MS Windows it’s better to specify Command devices like \\.\CMD-12345 instead of \\.\PhysicalDriveX where possible to avoid occasional drive mix after reboot.

UPDATE 2017.05.17. Anyway raidscan utility is preferable, as jpctdlistraid (HCS version 8.4.1-03) was unable to detect command devices on HUS150 arrays.
