HPE MSA 1050 Storage - Powering On/Off

Powering on/Powering off

Before powering on the enclosure for the first time:

  • Install all disk drives in the enclosure so the controller can identify and configure them at power-up.

  • Connect the cables and power cords to the enclosures as explained in the quick start instructions.

    NOTE: Power supplies used in MSA 1050 enclosures The MSA 1050 controller enclosures and drive enclosures are equipped with AC power supplies that do not have power switches (They are switchless). They power on when connected to a power source, and they power off when disconnected.
  • When powering up, make sure to power up the enclosures and associated host in the following order:
    • Drive enclosures first This ensures that disks in each drive enclosure have enough time to completely spin up before being scanned by the controller modules within the controller enclosure. While enclosures power up, their LEDs blink. After the LEDs stop blinking if no LEDs on the front and back of the enclosure are amber, the power-on sequence is complete, and no faults have been detected.

    • Controller enclosure next Depending upon the number and type of disks in the system, it may take several minutes for the system to become ready.

    • Hosts last (If powered down for maintenance purposes)

AC power supply

Enclosures equipped with switchless power supplies rely on the power cord for power cycling. Connecting the cord from the power supply power cord connector to the appropriate power source facilitates power on, whereas disconnecting the cord from the power source facilitates power off.

AC power cycle

To power on the system:

  1. Obtain a suitable AC power cord for each AC power supply that will connect to a power source.

  2. Plug the power cord into the power cord connector on the back of the drive enclosure. Plug the other end of the power cord into the rack power source. Wait several seconds to allow the disks to spin up. Repeat this sequence for each power supply within each drive enclosure.

  3. Plug the power cord into the power cord connector on the back of the controller enclosure. Plug the other end of the power cord into the rack power source. Repeat the sequence for the controller enclosure?s other switchless power supply.

To power off the system:

  1. Stop all I/O from hosts to the system.

  2. Shut down both controllers using either method described below:
    • Use the SMU to shut down both controllers, as described in the online help and web-posted HPE MSA 1050/2050 SMU Reference Guide. Proceed to step 3.
    • Use the CLI to shut down both controllers, as described in the HPE MSA 1050/2050 CLI reference guide.
  3. Disconnect the power cord female plug from the power cord connector on the power supply module. Perform this step for each power supply module (Controller enclosure first, followed by drive enclosures).
