Use this action to change the write-cache mode setting of a ready physical drive. The write-cache mode determines if the physical drive stores data before or after sending a confirmation to the controller.
Note: (Integrated RAID controller only) When you create an array, the physical drives must have the same write-cache mode setting. The default setting is write through. To set the write-cache mode to write back, you must change the write-cache mode on every physical drive in the array.
Attention: It is possible to lose data if a power outage occurs while using the write-back setting. Consider carefully whether to use the write-back setting on a physical drive. Depending on how you use the system, the write-back setting might be undesirable.
