It’s been a long time since I did a Tech Round
Up/Research Links & Info post (16th April 2015). There’s been an
accumulation of tech stuff in my personal inbox recently, time to clear them
down.
3 sections below:
- DevOps Stuff
- NetApp HCI
- NetApp Random Stuff
DevOps Stuff
1) Play with docker classroom
One of
my colleagues sent me this awesome link:
2) DevOps Tools
Image: Periodic Table of DevOps Tools
The same
colleague sent me this link to Periodic Table of
DevOps Tools. Whilst it’s very cool and all clickable with excellent links,
I’m not quite sure why it’s presented as a Periodic Table. If you’re boring

NetApp HCI
NetApp
released their NetApp HCI (Hyper Converged Infrastructure) product on 5th
June 2017. This looks like a great product and I hope to get my hands on some
in the future. It is based on their SolidFire platform. A few links:
And especially check out the following videos:
NetApp HCI Demo (You can
be up and running in about 30 minutes!)
Finally VMware Vvols start to make sense!

A bit more on NetApp HCI...
NetApp HCI allows you to start small (with just two chassis); and grow as needed, on-demand, and non-disruptively; to Enterprise Scale-Out levels.
Guaranteed Performance: Deliver All Your Applications with Confidence
Flexibility & Scale: Scale On Your Terms
Automated Infrastructure: Transform & Empower Your IT Operations

NetApp Random Stuff
1) NetAppDocs-Lite for Customer Collection
It’s no
secret that NetApp have an awesome tool for creating 7-Mode and ONTAP as-built
documentation called NetAppDocs. The full tool is only available to NetApp
partners and internal staff. Customers can download the NetAppDocs-Lite version
to collect the XML for NetApp partners/internal staff to process into as built
documentation. Check out this link:
2) One specific UNIX account is failing to
access its NAS data on NetApp Clustered ONTAP 8.3.2 post 7 to C transition
We had a
UNIX account that’s failing to access its data post 7 to C transition. Just one
UNIX account was affected. Running::>*
diag secd authentication translate -node NODE -vserver
VSERVER -uid UID
Results
in “Unable to retrieve UNIX username for UID”. It turned out that the following
7-Mode option was disabled (it’s hidden by default):
options nfs.authsys.extended_groups_ns.enable
But the
SVM had it configured. Disabling it fixed the problem::>
vserver nfs modify -vserver VSERVER -auth-sys-extended-groups
disabled
3) CN1610 Cluster Switches Hung to Management
(Telnet, SSH and Serial)
I’ve
known the CN1610’s become unmanageable a few times; telnet, SSH, serial - none
of those work. There is a way to break-in to the Linux shell and collect logs
for troubleshooting (so don’t just reboot the switch and accept it as a quirk).
Understandably this information is only available to NetApp partners and
internal staff. This is the link:
4) End of Engineering Support for Clustered
Data ONTAP 8.3.x on 31st October 2017
A date
to make a note of if your ONTAP systems are still on 8.3.x. Engineering Support
ends on the 31st of October 2017 (I understand that the end of
limited support is 30th April 2019.) This is a great excuse to get your
systems upgraded. Check out this link:
What
does end of ‘Engineering Support’ mean?
- Requests for bug fixes on the Data ONTAP
8.3.x release family will no longer be accepted. Fixes for issues that are
found on AFF, FAS, and V-Series systems that run Data ONTAP 8.3.x will be
delivered only in patch derivatives of ONTAP 9.x.
- Interoperability testing with Data ONTAP
8.3.x and updates to the NetApp Interoperability Matrix Tool will stop.
- Manufacturing and SAN qualification PVRs that
are specific to the Data ONTAP 8.3.x release family will not be accepted.
- For systems that cannot be upgraded to ONTAP
9.x, specifically FAS3240 and V3240, for the remainder of the customer’s
current support entitlement, NetApp will provide critical updates if NetApp
determines that they are necessary and commercially reasonable.
5) NetApp is No.1 in current quarter with 32% quarterly
revenue share in EMEA AFA (All Flash Array) market
