Poweroff procedure (+WAIT, UNPLUG!)
Shut down the system
The shutdown process can take between 25 to 45 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.
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:
On VNXe3100 and VNXe3150 systems, the shutdown process is complete
when only the Storage Processor Power LEDs are blinking and all
other Storage Processor LEDs are off.
7. If you are relocating hardware, disconnect cables in the
following order:
Disconnect the power cables from disk-processor enclosure (DPE)
to power down the SPs.
Disconnect the power cable from the DAEs to power them down.
