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.
Log entries are available from the CS: /var/log/messages and SP: cimomlog.txt

  1. Thank you, could have used this already, as there is very little information out there in how to power down a VNX 5500 or 5300…..
