Last week was the annual pilgrimage to Cisco Live in Melbourne. Well, normally it is. This year however I was unable to secure a free pass because let’s be honest here, the price of a full pass is extortionate. While the value of the event cannot be disputed the cost to get there can. Cisco Live is the best networking conference in Melbourne for those working in enterprise IT. I also mean networking in both senses of the word, networking technology and people networking. This year there were 7200 attendees and it promised to be an absolute cracker. But I was not going to be there.
I find conferences such as Cisco Live a great way to recharge the batteries and get re-inspired at work. You hear about all the latest and greatest and being out of your normal habitat changes how you approach solutions. Having the opportunity to meet experts and those that have literally wrote the book on a subject is invaluable. I’ve been to the past three Cisco Live events in Melbourne and I had hoped to keep that run going but unfortunately this year I was unable to secure a pass and it was too much of an expense to fund myself.
It wasn’t so bad though. We run our Cisco Data Center User Group (DCUG) on a monthly basis and it falls on the first Tuesday of Cisco Live so we had organised to have two international speakers for that. This would at least give me my fix. We were extremely fortunate to have Lukas Krattiger and David Jansen both extend their schedule to fit in the DCUG and provide a thoroughly enthralling session.
Last year I presented at the local Cisco DCUG to a warm and receptive audience about Cisco UCS Director being deployed on a global scale. At the time I was working for a global pharmaceutical company and following some organisational changes the requirements of the business and in turn IT changed to match. A key part of the changes focused on global standardisation of IT infrastructure to ensure 24 x 7 operational support. The best way to achieve that goal was to look at automation and orchestration. Cisco UCS Director was the tool chosen at the time. UCS Director is an absolute beast of a product and it reflects badly on Cisco as to how they have marketed and managed the product. It has potential to be the one stop shop for infrastructure management.
Create a global platform to enable physical and virtual automation based on standardised templates and processes.
- Drive standardisation across 14 global sites, reduce management overheads and complexities
- Put the company in a position to leverage follow the sun support for infrastructure to minimise out of hours support at each local site
- Provide a secure platform that could easily meet strict auditing guidelines
- Deliver a mechanism to allow end-users to quickly and easily request new virtual machines
- Streamline the request for infrastructure processes and remove existing bottlenecks
- Drive the business towards a Private Cloud architecture rather than individual silos
- Reduce licensing costs across the business for multiple existing automation and orchestration platforms.
- The ability to provide a cost model and service catalog and quickly inform projects on the estimated potential costs of their projects.
- Integration into the existing service management tool
- Integration into HP Quality Control for auditing and quality control purposes. This allowed for installation verification scripts to be completed.
Cisco Live Melbourne has come and gone for another year and this year was without a doubt the best of all the years I’ve attended so far. This was my 3rd year at CLMEL (#CLMEL) and it was an action packed week. At previous events I’ve been primarily going to the breakout sessions and giving myself a migraine from the amount of information I tried to chug through. This year I went in community mode. Being a Cisco Champion I was lucky to be able to partake in some special events, get some nice perk treatment such as prime seats for the keynote and also to interact with the other Cisco Champions. The number of Cisco Champions for Australia in 2017 has seen a significant increase and it’s heavily loaded towards Melbourne so CLMEL provided the ideal opportunity to meet new people.
Last year there were no real events so it was great to see some special Cisco Champions events organised and allow the Champions to meet up. This year Veritas, the events organisers, were on hand to assist with the Cisco Champion events throughout the week. A massive thank you to Freya for keeping things in check throughout the few days. A huge thank you also goes to Brandon Prebynski and Lauren Friedman of the Cisco Champions program for getting everything organised on the back end. The value added to the program during Cisco Live this year cannot be underestimated.
The first order of business on Day 1, Tuesday, was the Data Centre Innovation Day. This session provided an inside look at the upcoming technology roadmap for data centre tech. The Data Centre Innovation Day is by invite only and was organised for me by Lauren Friendman (massive thanks for that). I found the information on the upcoming roadmaps for UCS Compute, UCS Central and UCS Director platforms. I can’t divulge anything as it was under NDA but I can say some of it is pretty cool. One thing they did discuss which I can mention is the new interoperability matrix tool which has been updated to make it easier to search compatibility requirements. I haven’t played around with it yet but will most likely be using it for my next planned upgrade. Read More
The Cisco DCUG has been running for almost a year now and we’ve been very lucky with the support we’ve recieved from both Cisco and the IT community. Back in March, I know I’m well behind the times here due to other commitments, we were immensely privileged to have some top speakers present to the local DCUG.
Cisco Live opening day fell on the same day as our monthly DCUG meeting so it made sense to try to get some of the heavy hitters over from the US to present for us. Cisco DCUG ran with superstars Lauren Malhoit and Remi Phillippe. Lauren is well known within the IT community for her work on the In Tech We Trust podcast but also through her work on ACI. She’s got a course on Pluralsight around ACI if you’re interested in learning more about the Cisco technology. She’s recently jumped into a new role at Techwise TV. Lauren is also the author of a couple of books and an avid blogger for AdaptingIT.com and VirtualizationAdmin.com. Lauren is a massive presence within the tecnology community and I was immensely excited when she agreed to present at the DCUG. Remi is a TME within Cisco’s INSBU and has a heavy focus on the data center analytics platform, Tetration. A massive shout out goes to Rob Tappenden from Cisco in ANZ for helping to organise such quality speakers and initiating the initial contact. A small shout-out (almost at whisper-level) goes to Brett Johnson from vBrownBag for letting us know Lauren was making the trip out to Melbourne.
During a recent upgrade of Cisco B200 M4 blades I got the following error:
I really wasn’t sure what was causing the issue but it turned out to be a known bug for M4 blades. More details can be found over on Cisco BugSearch Note: You’ll need a Cisco Login to access the site. Basically the issue affects B200 M4 blades upgraded to 2.2(4) or higher.
The workaround is actually quite easy and just needs to have the FlexFlash Controller reset. This can be done using the below steps:
Step 1: Select Equipment -> Chassis # -> Server # -> Inventory -> Storage -> Reset FlexFlash Controller
Step 2: Click Yes to reset the FlexFlash controller
Step 3: Click Ok on reset notification
During a recent upgrade I ran into a problem with activation of B200 M4 blade. This was following the infrastructure firmware upgrade and the next step was to upgrade the server firmware. However, before upgrading the server firmware I got the error from the B200 M4 blades showing the following error:
Activation failed and Activate Status Set to Failed
This turned out to be due to the B200 M4 blades shipping with version 7.0 of the board controller firmware. On investigation with Cisco I found that it’s a known bug – CSCuu78484
You can follow the commands to change the base board. You can find more information on that from the Cisco forums but the commands you need are below:
#scope server X/Y (chassis X blade Y)
#activate firmware version.0 force
>Select a lower version than current one
What I found was that since I was going to be upgrading the blade firmware version anyway there was no point in dropping the server firmware back and instead proceed with the upgrade which fixed the issue.
I spoke with TAC and they advised that the error could be ignored and I could proceed with the UCS upgrade. The full details of the upgrade can be found in another post.
Recently I had to upgrade our ESXi hosts from Update 2 to Update 3 due to security patch requirements. This requirement stretches across two separate physical environments, one running IBM blades and the other running on Cisco UCS blade chassis in a Flexpod configuration. The upgrade paths for both are slightly different, and they also run on different vCenter platforms. Both of these also have different upgrade paths as one is running VMware SRM and is in linked mode. I’m not going to discuss the IBM upgrades but I did need to upgrade the firmware of the Infrastructure and Servers for Cisco UCSM.
Before you being any upgrade process I highly recommend reading the release notes to make sure that a) an upgrade path exists from your current version, b) you become aware of any known issues in the new version and c) the features you want exist in the new version
UCS Upgrade Prep Work
Check the UCS Release Guides
Check the release notes to make sure all the components and modules are supported. The release notes for UCS Manager can be found on their site. The link is listed further below in the documents section.
Some of the things to check within the release notes are:
* Resolved Caveats
- UCS Version Upgrade patch
- UCS Infrastructure Hardware compatibility
- Minimum software version for UCS Blade servers
Open a Pre-Emptive Support Call
I opened a call with Cisco TAC to investigate the discrepancy in the firmware versions. The advice was to downgrade the B200 M4 server firmware down to 4.0 (1). However, as I was planning on upgrading anyway I’ve now confirmed that the best option is to upgrade to the planned 3.1 version. As part of this upgrade I will also upgrade all the ESXi hosts on that site the same day. There is a second UCS domain on another site that will be upgraded on another date.
Last week I had the opportunity to attend Cisco Live in Melbourne and it was awesome. This is the second year I’ve attended Cisco Live but this year I was there as an Attendee so I had access to the breakout sessions. Previously I only had an Explorer Plus pass which was good for the keynote access, partner theatre sessions and the World of Solutions. While that was fun experience getting access to the breakout session was what I really wanted, and they didn’t disappoint. I’m privileged in that my ticket to Cisco Live was covered by my employer that sees the value in such events and we were also able to leverage Cisco Learning credits. If you wish to attend and have these credits available to you this is a great return on investment and one I’d recommend over a regular 5-day training course.
This year Cisco Live was once again held at Melbourne Convention Centre and it’s a brilliant facility that has a great layout, is large enough to cater for the ever-growing number of attendees and is easy to access via public transport. The breakout sessions are full on and a number of people had mentioned beforehand that going to Cisco Live was like drinking from a firehose. They weren’t wrong. Cisco tee up the sessions and you try to cram as much as you can into your grey matter. I also chose to sign up for an extra day technical seminar which was an 8 hour session on Cisco UCS. There were a number of streams that could be chosen but my focus is on UCS. This was an added extra on top of the regular attendee ticket. During the remainder of the week I tried to cram in as many other breakout sessions as I could and catch a few of the partner sessions as well as have some downtime to network a bit.
After a recent upgrade to UCS Director 5.4 I noticed that my storage connections were showing a status of failed on the dashboard. I went to Administration -> Physical Accounts -> Physical Accounts. All of my NetApp controllers were offline.
I went to edit settings and re-entered my password to make sure that it had been picked up correctly.
All the settings were fine so I saved them and tested the connection to the controllers again.
The connection failed with the following error:
500 Connection has been shutdown: javax.net.ssl.SSLHandsakeException:
Server chose SSLv3, but that protocol version is not enabled or not supported by the client.
After the recent upgrade to 5.4 I decided to bite the bullet and upgrade to 5.4.1. Go to the download software portal for Cisco. Download the 5.4.1.zip patch file. I had a number of issue with the download as the checksum didn’t match. I had to take a number of attempts to get the file in-tact. I believe the issue was the ISA that acts as our internet proxy. Death to the ISA!!!!
Once the file has been downloaded copy it to your FTP server. Now it’s time to apply the patch. log onto UCS Director via either the console or SSH using the shelladmin account. Select option 3 to stop all the services.
