Here is a little test. Check your documentation: Do you know how to power down and power up the equipment in your computer room? If you had to power off your site in a hurry would you know how? If you wanted to script a shutdown, could you do it?
Here are some hints and tips that might help you with some of my favourite products:
The process to power up or down your DS8000 is documented in the Information Center here.
If you want to script powering off a DS8000 storage unit you can use the chsu -pwroff DSCLI command. This command will shut down and power off the specified DS8000 unit. Be careful before powering off the unit to ensure that all I/O activity has been stopped. An example of the command is shown below. Your machine will have a different IP address, password and serial number to mine. Note the serial number always ends in zero because we send the command to the storage unit.
dscli -hmc1 10.1.60.240 -user admin -passwd passw0rd chsu -pwroff -dev IBM.2107-75DC710
It takes over a minute before you will see any change in the machine. So be patient. The HMC will not power off. You can either leave it powered on or shut it down manually.
To power the DS8000 back on, use the chsu –pwron command:
dscli -hmc1 10.1.60.240 -user admin -passwd passw0rd chsu -pwron -dev IBM.2107-75DC710
Storwize V7000 and SVC
The SVC Information Center explains the process to power down and up here.
I created a short video on how to shutdown your Storwize V7000 using the V7000 GUI. You can view it on Youtube:
