Drive Sanitization

¡: Allowed / ´: Not allowed (cold swap is possible) / —: Not applicable
*1: Mid Plane. A board that is located between the front and rear (SVC or FRT, CM or IOM side) of the ETERNUS DX.
*2: 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 continue operation.
*3: When hot expanded, each CM must be pulled out to expand. Therefore, all host interfaces on the CM to be expanded will temporarily go
offline.
*4: Bootup and Utility Device.
*5: An I/O suspension may be required depending on the firmware changes.
*6: Can be replaced for configurations with two CEs.
All of the paths on the CE that will have maintenance performed go offline. When a multipath configuration is used, switch to the host
paths of the CE that will not have maintenance performed to continue operation.
*7: Operation can be continued during a failure. The status of the DE can be monitored via ETERNUS Web GUI or ETERNUS CLI.
*8: FEMs are installed in high-density drive enclosures.
Drive Sanitization
Drive sanitization is a function that deletes data in a drive using the sanitization function of the drives (SSDs,
Online SAS disks, or Nearline SAS disks). The drive sanitization function can be used to delete user data when,
for example, discarding drives.
Caution
The Maintenance Operation policy is required to sanitize the drives. Also, change the status of the
ETERNUS DX to the maintenance status.
