Power off a Technology Extension with Isilon Storage

Prerequisites

  • WARNING:The Technology Extension for Isilon Storage must be powered off after the PowerFlex rack is powered off.
  • See the relevant procedure in this publication for powering off the attached PowerFlex rack.
  • Look at the back panel and confirm that the LEDs on both batteries are green. If either battery is red, it has failed and must be removed from the node. If both batteries are red, replace and verify them before shutting down the node.
  • Take a backup switch configuration using below command and store the backup file to a remote server: 
    Copy running-config startup-config
copy startup-config tftp://<server-ip>/<switch_backup_file_name>

Steps

  1. Open OneFS and log in as root.
  2. Click CLUSTER MANAGEMENT > Hardware Configuration > Shutdown & Reboot Controls.
  3. Select Shut Down.
  4. Click Submit.
  5. Power off the Switches in the Technology Extension for Isilon Storage cabinet.

Results

Verify that all nodes have shut down by looking at the power indicators on each node.
If nodes do not power off:
  1. SSH to the node.
  2. Log in as root and type: 
    Isi config
  3. In the subsystem, type: 
    shutdown #

    Where # represents the node number, or type: 

    shutdown all

If the node still does not power off, you can force the node to power off by pressing and holding the multifunction/power button on the back of the node.

If the node still does not respond, press Power button of the node three times, and wait five minutes. If the node still does not shut down, press and hold Power button until the node powers off.

NOTE:Perform a forced shutdown only with a failed and unresponsive node. Never force a shutdown with a healthy node. Do not attempt any hardware operations until the shutdown process is complete. The process is complete when the node LEDs are no longer illuminated.
