HP 3PAR CheckHealth Command

If you are running a HP 3PAR storage array you want to be certain it’s in a healthy state at all times. While you could look through all of the management menus to check the status of components it’s far easier to leverage the checkhealth command.

Let’s take a look at the command and some of it’s options.

First we will connect to the 3PAR array (in this case a 3PAR simulator) via SSH.

I will connect using the standard 3PAR administrator account, if you have not changed the default password it will be as follows –

  • Username – 3paradm
  • Password – 3pardata

I would strongly recommend you change default passwords or better yet create a separate service account.


Once we are connected to the array we can enter the checkhealth command.

Checkhealth Command

As you can see the command executes providing feedback on each stage followed by a summary of any outstanding issues. As I mentioned above I am running this test on a copy of the 3PAR simulator so I fully expect to see some problems here.

Of course in an ideal world you wouldn’t want to see any issues listed in the summary but to be honest the odds are you are going to see something now and then.

We can leverage the help command to see additional information and options for checkhealth.

Help Checkhealth Command

As you can see there are a few command switches we can use, typically I use the –detail switch to get a complete review of the array.

Checkhealth -detail Command

You can see that additional output is provided, again as this is a simulator you will see issues which shouldn’t occur in an actual array.

If you wish to check a single component you can append this to the command as below.

Or if you wish to check a number of components.


There are of course other ways to check the health of your array with things like proactive alerts from the service processor (SP) or via other management tools and I will probably cover these in a future posting at some point.

For reference here is the full help output for the command –
