Powering off the Storage System

Powering off the Storage System

The storage system power-off sequence is to first power off storage devices and then turn off PDU switches. Respect the power-off sequence when you power off storage devices for not using them, replacing cabinet enclosures, or responding power link failures.

Prerequisites

No service is running on the storage system.

Context

The operation of turning off PDU switches varies based on types of PDUs configured.

  • North American standard PDUs:

    Insert a flat-head screwdriver or a clip into the hole located above the word OFF on the switch, and push forward gently until the upper part of the switch pops up.

  • European standard PDUs and HVDC PDUs:

    Turn the switch downward.

Procedure

  1. Power off the storage device.

    NOTE:

    You can power off the storage system by holding down the engine power button for five seconds or performing power-off operations on DeviceManager. This section uses the operations on DeviceManager as an example.

    1. Log in to DeviceManager.
    2. Choose Settings > Power Off Device.
    3. Confirm the information in the displayed Danger dialog box, enter the password of the currently logged on user, and then select I have read and understand the consequences associated with performing this operation.

      If you enter the wrong password three times in succession within 5 minutes, the current user will be logged out and exit DeviceManager.

    4. Click OK.

      The Success dialog box is displayed, indicating that the operation succeeded.

    5. Click OK. You have powered off the storage device.

  2. Turn off the PDU switches in every bay in the right sequence.

    • The sequence to turn off the PDU switches is as follows:
      • When the system is equipped with disk bays, first turn off the PDU switches on the system bays, then on the disk bays.
      • Turn off the PDU switch on all system bays from system bay 0 to system bay n in sequence.
    NOTE:

    For details about turning off PDU switches, refer to Context.

    • You can turn off the storage system that is configured with European standard PDU switches as follows:
      1. Turn off PDU switches of the system bays from system bay 0 to system bay n in sequence.
        • For European standard PDU switches (single-phase, 220 V, 32 A), turn off the switches in a sequence of B2 > B1.
        • For European standard PDU switches (three-phase, 380 V, 32 A), turn off the switches in a sequence of C2 > C1 > B2 > B1 > A2 > A1.
      2. Turn off PDU switches of the disk bays.
        • For European standard PDU switches (single-phase, 220 V, 32 A), turn off the switches in a sequence of B2 > B1.
        • For European standard PDU switches (three-phase, 380 V, 32 A), turn off the switches in a sequence of C2 > C1 > B2 > B1 > A2 > A1.

          Figure 5-16 and Figure 5-17 show switches on a European standard PDU switches.

    • You can turn off the storage system that is configured with North American standard PDU switches.
      1. Turn off PDU switches of the system bays from system bay 0 to system bay n in sequence.

        For North American standard PDU switches, turn off the switches in a sequence of B3 > B2 > B1.

      2. Turn off PDU switches of the disk bays.

        For North American standard PDU switches, turn off the switches in a sequence of B3 > B2 > B1.

        Figure3 Switches on a North American standard PDU shows North American standard PDU switches.

    • You can turn off the storage system that is configured with HVDC PDU switches as follows:
      1. Turn off PDU switches of the system bays from system bay 0 to system bay n in sequence.

        For HVDC PDU switches, turn off the switches in a sequence of B2 > B1.

      2. Turn off PDU switches of the disk bays.

        For HVDC PDU switches, turn off the switches in a sequence of B2 > B1.

        Figure4 Switches on an HVDC PDU (240 V, 32 A) shows HVDC PDU switches.
