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:
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 Name : 3PAR1
System Model : HP_3PAR 7200c
Serial Number : 1666666
------------------Partial List Of Hosts-------------------
Id Name Persona -WWN/iSCSI_Name- Port IP_addr
ANY HOSTS STIL CONNECTED LISTED HERE
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 AO. Then follow the hardware steps in the following section.
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
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 check health after power up to check everything looked OK.
