(Example 1) Setting the Eco-mode schedule via ETERNUS Web GUI
(Example 2) Setting the Eco-mode schedule via ETERNUS Web GUI
• Eco-mode schedules are executed according to the date and time that are set in the ETERUS
DX Disk storage system. To turn on and turn off the disk motors according to the schedule
that is set, use the Network Time Protocol (NTP) server in the date and time setting in
ETERNUS Web GUI to set automatic adjustment of the date and time.
• Up to four disks can be activated at once in a single enclosure. When attempting to activate
more than four disks at once, the first four of the disks are activated, and then the rest of the
disks are activated. When this happens, the server will see increased response times and
access paths may be lost, in which case the RAID configuration or disk installation status may
need to be reviewed.
