Some of you had asked to know when this was released so here it is. Please, as always take time to read through the release notes and the admin guides to familiarize yourself with the changes. There are new commands and some have been retired.
A couple of key things for this release:
Support for the EXN 3000 disk shelf
Port based load balancing option for multimode VIFs
There is a lots of good information in the release notes that a lot of people miss and end up calling support. Everything in the document is linked so you can quickly move around and find things easily.

A packet is sent down the line and it comes to a fork in the channel, does it pick the right way? Only if you tell it.
With N series active/active configurations, you can see a lun from both controllers. This sometimes confusses people and they end up picking the wrong path to the hosting controller. The I/O that should be going directly to the primary controller is now going through the ‘partner’ and over the interconnect. This does increase the amount of workload each system has to put out as it handles the extra traffic.
Typically there are a few things to check when trying to diagnose the issue.
- Identify the LUNs being accessed through the partner node’s FCP Target port.
a. lun stats -o (LUN STATISTICS)
- Identify the host initiators that are performing the I/O through the partner path
a. lun config_check -A (LUN CONFIG CHECK)
b. lun show -v (LUN CONFIGURATION)
c. igroup show -v (INITIATOR GROUPS)
- Identify the primary storage controller FCP target ports available for access to the LUN.
a. fcp show cfmode (FCP CFMODE)
b. fcp show adapters (FCP TARGET ADAPTERS)
- Verify the host initiator connectivity to primary FCP target ports and the host MPIO software configuration.
- Verify use of the partner path has ceased from both cluster nodes.
a. sysstat -b 1
Also make sure your MPIO settings are correct and not affecting the system path. All hosts should also be running the host utility kit provided by IBM.
With these techniques you should be able to clear up any mis-directed I/O. As with any correction, if you are not sure please contact IBM Support at 1.800.IBM.SERV or open a service request ticket at IBM Online Support Portal

You just received your new N series system and after plugging it all up, you want to read up on how configure autosupport. Or maybe, you want to chat with others about the best way to setup a cifs share. Whether you are an experienced user or just starting out, we have all of the information you need to get through the install, administrate the day to day activities and if needed a recovery.
I put together a list of topics / links people are always asking me to send to them.
Your N series system has to be registered with the current information so IBM Support can contact you and you can get access the IBM Support Page. To begin this process go to the following link and start your process with the overview of this process in step 1.
You can now customize your support page with IBM Support Portal. Here you can select your different IBM products (storage, servers, software…).
My IBM is where you can sign up for notifications on IBM products.
To download code from IBM you have to be signed into the support site and choose Data ONAP as your storage family, then click download.
On the next screen you will click on the link at the bottom for Software Packages for registered users.
The following pages allow you to choose your product to download. If you do not see a product that you purchased on the page, contact your local account team or call 1.800. IBM.SERV for support (See below for more instructions on contacting support via phone).
All of the IBM documentation is based on the release of Data Ontap. The best way to get to the documentation is the through the ‘Matrix’. From the same screen you used to get the software download, click on the N series Data ONTAP Matrix link at the bottom:
From here you find release notes and publications that will assist you with every aspect of your N series system and environment.
Here is a quick link to the latest (October 12, 2009) release of publications. You will have to either be logged in or the site will prompt you to login.
This page has tons of information that you will need for administrating and recovering your system and more. Here is a list of topics:
- General Information
- Data Access Protocols
- Storage Management
- Data Protection/Recovery
- Command References
- Autosupport and Troubleshooting
Ask questions and chat with IBM team members about N series and other products:
Professionally written Redbooks and Redpapers on N series and other technologies.
A couple of suggestions:
There are over 60 Redbooks written about N series and its software components. Need help with virtualization, Exchange, SQL, SAP? This is where you will find it.
Opening a service ticket:
Currently there are two ways to open a service ticket with IBM support; calling 1.800.IBM.SERV or through the website.
1. Calling IBM.SERV
When calling IBM.SERV you will have two options: Hardware or Software. Your warranty for break fix covers both the system and the software that was sold to you. If you are needing a part fixed or if an error is occurring with your software, you will choose option 1 for Hardware.
If you have purchased a supportline contract from your account manager, then you will be able to ask IBM any type of installation or configuration question by choosing option 2 for Software.
Typically if you do not know which option to choose, then select option 1 and our Level 1 team will transfer you to the appropriate team as needed.
As with any IBM production you will be asked for the Machine type and serial when calling. This can be found on the front bezel of the machine or in the header of your autosupport:
===== SYSCONFIG-A =====
> Data ONTAP Release 18.104.22.168: Wed Jun 25 11:01:02 PDT 2008 (IBM)
> System ID: 0101224997 (toasterA); partner ID: 01014303234 (toasterB)
> System Serial Number: 2864130990522 (toasterA)
Look for the Serial Number listing, the first four digits are your model, the next 7 digists are the serial number.
2. Through Webpage
If you wish to submit a ticket to through the IBM Support site simply click on the link in the blue box (on the right side of the page).
After answering your questions the ticket will be submitted to the IBM Support team who will call you to resolve your issue.
If for any reason you do not receive the level of support you deserve, you can always call the 1.800.IBM.SERV number and ask to speak to Duty Manger. This person will always be available and can be an advocate for you when you need someone.
There have been plenty of you that have said the IBM support site is hard to navigate. You wanted a quick way of finding things that only pertain to your environment. Finally, IBM now has a way to do both, introducing the IBM Support Portal.
The portal is very user friendly and allows me to pick up to t10 different items that I want to keep up to date on. For Example, If I have a N7900 and a HS20 Blade and some System X server, I can choose all three on my portal and get information on the latest updates, news and flashes.
When you click on the link it will take you through a couple of simple questions to get an idea of what things you are looking for on the IBM support site. Once this is done you can then customize the portal with different types of downloads, forums, tools and so much more.
