VNX VG2 and VG8 planned powerdown

Step Action

1. Do the following before you power down the server:

a. Notify all users of the planned powerdown several days in advance when possible.

b. Prevent all logins and notify all users several minutes in advance of the impending

powerdown.

c. Log out all users.

2. To perform a planned powerdown, you should be within close proximity of the server.

• From the Start menu, select Programs > Accessories > Communications >

HyperTerminal.

• Type a session name and click OK.

• Select the COM port that the cable connects to in the Connect Using box and click OK.

• Type the following port settings:

• Bits per second: 19200

• Data bits: 8

• Parity: None

• Flow Control: None

• Emulation: Auto Detect

• Telnet terminal ID: ANSI

3. Verify the system’s health, type:

$ /nas/bin/nas_checkup

The checkup command reports back on the state of the Control Station, Data Movers, and

storage system.

Note: This health check ensures that there are no major errors in the system that would

prevent the system from being turned on during the power up process.

4. To halt the VNX for file server, type:

# /nasmcd/sbin/nas_halt now

ARE YOU SURE YOU WANT TO CONTINUE? [ yes or no ] :

# yes

Sending the halt signal to the Master Control Daemon...: Done

Halting system...

flushing ide devices: hda hdd

Power down.

It can take as long as 20 minutes to halt the server, depending on the configuration of the

VNX. Wait until the command completes before continuing. If the Control Station halted

successfully, the HyperTerminal session will be unresponsive.

If the Control Station restarts after the nas_halt command, then go to step 6. If the Control

Station has halted successfully, then go to the next step to restart the Control Station.
