Shutdown via UNISPHERE using the Service Account

VNXe-Shutdown

Please read all notes provided in the ‘More Information..’ section highlighted in the above image before proceeding with shutdown.

Shutdown process as documented in the ‘More Information..’ section:
1. From Unisphere, select Settings > Service System.
2. Enter the Service password to access the Service System page.
3. Under Service Actions, select Shut Down System.
4. Click Execute service action to shut down the storage processors (SPs).
5. In the Service Confirmation dialog box, click OK.
6. Check the status of the shutdown process by looking at the SP LED indicators. The shutdown process is complete when all the Storage Processor Power LEDs are flashing green, the SP Status Fault LED is solid amber, the network management port LEDs are on, and all other Storage Processor LEDs are off.


Shutdown via SSH using the Service Account:

Shutdown command:

EMC XtremIO Shutdown Procedure

The below steps outline how to perform a clean shutdown of an XtremIO array and thus help prevent any case of data corruption or loss. Before proceeding with the shutdown task ensure that all connected hosts are powered off. Running the ‘show-clusters-performance’ command from the XMS console will help determine that no I/O requests are being sent/received from a host. As you can see from the output below all I/O to the X-Brick’s has ceased and it is now safe to proceed:

XIOShut1

The ‘show-clusters’ command should display a status of Active and Connected:

XIOShut2

In order to shutdown the service run the stop-cluster-unorderly command. On completion the “Unorderly stopped Cluster” message appears:

XIOShut3

The ‘show-clusters’ command should now display a status of “stopped (unorderly)”:
XIOShut4

At this stage you may proceed with powering off the X-Bricks by turning off the rack’s PDU (to which the cluster is connected). The XMS can then be shutdown by running the cmd ‘shutdown-xms shutdown-type=machine’.
XIOShut5

To start the cluster:
start-cluster

EMC VNX – New Shutdown Options

Note: Please ensure to reference official EMC documentation before proceeding and ensure your system health checks are passed before completing a shutdown.

A new feature with the release of VNX Rockies(Block OE 5.33 & File OE 8.1) was the ability to Shutdown the Entire Array using either a single command or via the ‘Power Off’ button in the Unisphere GUI. This feature is also available for first generation VNX storage system’s, from VNX OE code release 05.32.000.5.209 & 7.1.74.5 onwards.
These options are supported on Unified, Block and File systems.

Power Off via CLI
The new CLI option extends the nas_halt command to include a new switch to power down the entire system :
nas_halt –f –sp now
This will power off Control Stations, Data Movers and the Storage Processors.
usage: nas_halt [-f] [-sp] now
Perform a controlled halt of the Control Station(s) and Data Mover(s)
-f Force shutting down without prompt
-sp Shut down Storage Processors on unified platforms

nas_halt can only be executed by root users and must be run from the /nas/sbin directory

Power Off via Unisphere
From Unisphere GUI navigate to the System List page:
SHUT1

Once you hit the ‘Power Off’ button a dialog box appears and from here you enter the array serial number in order to confirm shutdown:
SHUT2

Final Confirmation:
SHUT3

Note:
DAEs are not powered off.
