Instructions

Before you begin
  • The system shut down or power down procedure involves shutting down the Storage Processors (SPs). When all SPs are down, all I/O services stop and hosts lose access to the system. Before performing this procedure, it is recommended that you power off all connected hosts and they remain powered down while the Unity system is offline you do not need to disassociate the datastores/LUNs/NAS shares. They need to be powered down before the SPs and powered on after the SPs are fully online.
  • The shutdown process can take between 10 to 20 minutes to complete. During this time, the connection to the system will be lost and you will not have access to Unisphere or the online help. It is important that you print the power up instructions on this page to be sure you have all of the information you need to power up the system. When Unisphere is not available, you can go to the support website to locate product documentation.
  • For physical deployments, working with hardware may cause electrostatic discharge that could damage your hardware. Before working with any hardware, review the precautions when removing or replacing components.
  • Shutting down the system with this method shuts down the storage system without putting storage processors (SPs) into Service mode, and does not require any additional SP boots. When the system is powered back up, the SPs come up in the same mode that they were in when the system was shut down.
IMPORTANT NOTE: See the DC-Powered Unity Enclosures: Installation and operation guide for instructions on how to power down and power up a DC powered system (physical deployments only).


Power down procedure

For virtual deployments:
 
Execute the Shutdown System task and confirm. The VM is automatically powered down. Or you can power down the system from the VMware vSphere Client. For more information, refer to the VMware documentation. Dell EMC recommends using the "Shut Down Guest OS" to gracefully power down the OS and VM. Do not use Power Off.

For physical deployments:
  1. In Unisphere, select Service, under the System heading, then select Service Tasks.
  2. Select Storage System > Shut Down Storage System, then Execute.
  3. Check the status of the shutdown process by looking at the SP LED indicators. The shutdown process is complete when the two power supply LEDs are solid green and amber, the network management port LEDs are flashing amber and green, and all other SP LEDs are off.
  4. After confirming successful SP shutdown, remove all power from the SPs by disconnecting the two power cables from the Disk Processor Enclosures (DPE). Wait 10 seconds and confirm that both the green and amber LEDs have turned off after the power cables are removed.
  5. If you are relocating hardware, also disconnect the two power cables from each Disk Array Enclosure (DAE) to power them down.

Power up procedure

For virtual deployments:
 
Power up the system using the VMware vSphere Client. For more information, refer to the VMware documentation.
  1. Launch VMware vSphere Client.
  2. Locate the UnityVSA VM and select the Summary tab.
  3. Select Power On to start the VM.
For physical deployments:
  1. Reconnect the power cables to each DAE in the following exact order:
  • DAE 0
  • DAE 1
  • DAE 2
  • Power up any remaining DAEs in ascending order.
The front blue Power Status LED on each DAE turns on.   
  1. Reconnect the power cables to each SP in exactly this order:
  • SP A
  • SP B
The rear green SP Power LED on each SP turns on.
  1. The SPs should come up in the same mode that they were in when the system was shut down. If a single SP comes up in Service Mode, in Unisphere, you need to reboot the SP to return it to Normal Mode.

CAUTION: If both SPs reboot in Service Mode, always return SPA to Normal Mode first, to avoid management software conflicts Once SPA is operating normally, you can return SPB to Normal Mode.
