*1: All of the host interfaces on the CM that will have maintenance performed go offline. When a multipath
configuration is used, switch to the host paths of the CM that will not have maintenance performed to con-
tinue operation.
*2: System volumes must be created if Unified kit/Unified License is installed.
*3: When hot expanded, each CM must be pulled out to expand. Therefore, all host interfaces on the CM to be
expanded will go offline.
*4: Bootup and Utility Device.
*5: Depending on the changes in the firmware, this function may require I/Os to be temporarily stopped.
*6: Mid Plane. This is a board that is located between the front and rear (controller (CM) or I/O module (IOM)
side) of the ETERNUS DX.
*7: Operation can be continued during a failure. The status of the ETERNUS DX can be monitored via ETERNUS
Web GUI or ETERNUS CLI.
*8: FEMs are installed in high-density drive enclosures.
SSD Sanitization
The SSD sanitization function deletes data in the SSDs by using the sanitization function of the SSDs. The SSD
sanitization function can be used to delete user data for cases such as the disposal of the SSDs.
Executing the SSD sanitization function (or the sanitization command) initializes the entire NAND (or data/alter-
nate areas) of the SSDs. The SSDs can be used again after the SSD sanitization function is executed.
The Maintenance Operation policy is required to sanitize the SSDs. Also, change the status of the ETERNUS DX
to the maintenance status.
