Shutting Down a 3PAR

I recently did the power down of a datacentre containing a 3PAR and wanted to quickly cover off the steps that I followed to power off and then back on.

First of all I did a health check to check for any issues such as a failed disk:

3PAR1% checkhealth
 Checking alert
 Checking cabling
 Checking cage
 Checking cert
 Checking dar
 Checking date
 Checking fs
 Checking host
 Checking ld
 Checking license
 Checking network
 Checking node
 Checking pd
 Checking port
 Checking rc
 Checking snmp
 Checking task
 Checking vlun
 Checking vv

All looked OK so I proceeded with the shutdown.  You have 3 methods to shutdown SPmaint, SPOCC or via CLI.  I would recommend using SPmaint, or SPOCC  if possible.


1 Connect via web GUI to your Service Processor

2 Select SPmaint on the left hand menu

3 Choose StoreServ Product Maintenance


4 Choose halt a storeServ cluster/node


5 Choose to shutdown the cluster, not the separate nodes

6 Wait about 5 minutes, then follow the hardware steps later in the post


You will need to logon with a local admin account

To begin the shutdown:

3PAR1% shutdownsys halt

You will See the following prompt

-----System Information------
 System Name   : 3PAR1
 System Model  : HP_3PAR 7200c
 Serial Number : 1666666

------------------Partial List Of Hosts-------------------
 Id Name       Persona       -WWN/iSCSI_Name- Port  IP_addr

Shutting down this storage system will impact applications running on the hosts displayed above

Do you REALLY want to HALT this storage system? yes or no:

The system will HALT in 12 seconds

Press the enter key to stop...


No tasks can be running such as Adaptive Optimization. Then follow the hardware steps in the following section.

Hardware Steps

1 Wait aprox 5 mins for shut down

2 Check the node Status LED is flashing green and the node hotplug LED is blue

3 Turn off the node PCM switches at the back of the controller nodes. (Diagram borrowed from HP 3PAR StoreServ 7000 and 7000c Storage Service Guide)

4 Turn off the node PCM switches at the back of the disk shelves


Power On

3PAR will automatically turn its self back on when power is detected so you will just need turn the PCM switches back on.  The order is the reverse of power off:

1 Turn on the node PCM switches at the back of the disk shelves

2 Turn on the node PCM switches at the back of the controller nodes


It would of course be sensible to do a checkhealth after power up to check everything looked OK. If you found this useful you will be interested to see our selection of the best 3PAR posts selected from the 150 posts written on the topic within this blog.

  1. One recommendation (even from HPE)… Before turning off the 3PAR system, activate the maintenance mode so HPE can safely ignore any erros received from the 3PAR system during that period and avoid some false cases open on HPE side 😉

    That can be done on SPMAIN -> 3- StoreServ Configuration Management -> INFO

    You can choose a pre-defined period or use a custom one. If the maintenance is for an unknow period I usually choose like 9999 minutes, and after maintenance is over I’ll go there again and disable maintenance 😉
