SVC or Storwize V7000 Customer? You have homework!

The Storwize V7000 and SVC release 6.1 introduced a new WEB GUI interface to assist with service issues, known as the Service Assistant. The Service Assistant interface is a browser-based GUI that is used to service your nodes. Much of what you traditionally did with the SVC front panel can all be done using the Service Assistant GUI. You can see a screen capture of the Service Assistant below:
While I would like to be optimistic and hope that you will never have to use the Service Assistant, you should always ensure your toolkit is equipped with every possible tool. I say this because one thing I have noted is that the majority of installs are not configuring the Service Assistant IP addresses. This is particularly apparent as clients upgrade their SVC clusters to release 6.1.
By default on Storwize V7000, the Service Assistant is accessible on IP addr
Its an easy five step process as shown in the screen capture below. Go to the Configuration group and then choose Network (step 1). From there select Service IP addresses (step 2) and the relevant node canister (step 3). Choose port one or port two (step 4) and then set the IP address, mask and gateway (step 5).
You can also set them using CLI (replace the word panelname with the panel name of each node, which you can get using the svcinfo lsnode command).
satask chserviceip -serviceip 10.10.10.10 -gw 10.10.10.1 -mask 255.255.255.0 panelname
If you forget these IP addresses, you can reset them using the same CLI commands or using the Initialization tool as documented here.
Finally having set the IP addresses, visit the service assistant by pointing your browser at each address. This is just to confirm you can access it. You logon with your Superuser password. With the process complete, ensure the IP addresses are clearly documented and filed away. So now if requested, you will be able to perform recovery tasks (in the unlikely chance they are needed). If for some reason your browser keeps bringing you to the normal GUI rather than the Service Assistance GUI, just add /service to the URL, e.g. browse to
So what should you do now?
If your an SVC customer on SVC code version v5 and below, please get two IP addresses allocated for each SVC I/O group, so you can set them the moment you upgrade to V6. Do this once the upgrade is complete.
If your an existing Storwize V7000 client or an SVC client already on V6.1 or V6.2 code, then hopefully you should already have set the service IP addresses. If not, please do so and test them.
