I have a customer who is using HP Intelligent Management Center (IMC) to monitor their switching environment. Originally they were using all HP Switching, but have slowly moved away during a refresh cycle and now use Cisco Switching, a mix between 2960X and Nexus switching.
When changing the HP IMC (Basic edition licence) over to manage the Cisco switching, everything went fine, apart from the Nexus 9K switches, which were not detected properly nor could be backed up. We contacted HP, who said the 9K switches are supported, but they would not give us any further details until we had a software support contract in place.
When we ran a manual backup of the switch we would receive the following error message;
Failed to send the configuration file from the device to the iMC Server by TFTP
The cause is down to the sysOID seen by IMC, it correctly see’s the vendor a Cisco switch, but does not identify it as a Nexus switch. The default settings for a Cisco Switch in IMC is to use CatOS commands for any operation.
There is two reasons as to why you would be taking this exam. The first is because you want to achieve the CCNP Datacenter title, or the second is because your company requires you to, so they can achieve the Unified Computing Technology Specialization.
My reason was the second, but the Cisco Datacenter track is something I am interested in in the long run.
If your going for the partner route like me, you are not required to have the CCNA DC under your belt. But if you want to achieve the CCNP DC, you need to complete the correct pre-reqs, which can be found here.
The exam is 90 minutes with around 70 questions. The recommendation is to undertake the Designing Cisco Data Center Unified Computing course from an authorised Cisco Learning Partner. Which is exactly what I did, and then sat the exam straight after.
I will blog about the course separately.
So the exam was the usual Cisco, its made of majority multiple choice questions, and I also had two small testlets.
My previous posts in the series covered getting the Cisco UCS up and running and into production, and it seems that adding how to upgrade the Firmware on the UCS at the end of the series is best, as you will find yourself needing to do this once the system is in production as well.
Note: Many thanks to Rene again for this simple post helping me through the steps.
Note2: It’s also worth looking through this short article on the do’s and don’t of UCS Firmware updates, from a session held at Cisco Live 2014.
My most recent customer engagement, was to re-use some older hardware as vSphere disaster recovery. The kit includes a EMC Clariion SAN, and two Cisco MDS 9124 switches.
The customer didn’t setup these FC switches, and required a password reset. Which I was happy to do for him, until I realised the Cisco article online is slightly wrong. So below are the steps I took to get the job done.
Password Reset/Recovery Steps
First off stick your console cable into the switch,
1. Power Cycle the Switch and keep pressing Ctrl + C until you see;
2. You then need to find the boot filename, using the “dir” command
