VCP6-DCV Exam Notes

It’s nearly 5 years since I took my VCP5, and my VCP510 notes from October 2011 still rank as vCosonok’s most viewed post (I seriously don’t expect this post to be anything like as popular - I’m very late to the VCP certification prep party this time); now time to upgrade to VCP6!

Firstly, what do I need to do to get the VCP6-DCV?

I did my VCP5-DCV Exam (VCP510) back in October 2011, and discovered that my VCP has since expired, so I just hold an expired VCP certification, this means I need to do a training course, vSphere 6 Foundations Exam, and VMware Certified Professional 6 - Data Center Virtualization Exam.

Course: Through work I was able to attend the “vSphere: Install, Configure, Manage [V6]” course
Exam 1: vSphere 6 Foundations Exam ($120 - online exam)

Check out the following VMware.com links:

Resources on MyLearn.VMware.com

Check out the Exams and Exam Topics:


*I’ve put the Delta Exam link down for those who need to do the full exam, but essentially just need to cover what’s new.


Tip: Before starting in-depth study, first try out the practice exams, you might know more (or less) than you think, and make notes!

Assorted Links (top links from a Google of “VCP 6 Exam Cram Notes”)

There is an awesome amount of content out there to help you with your VCP6, an incredible amount of effort must have been put in. I’d suggest finding the study guide you like the most and study that comprehensively, making notes as you go along. If you finish one study guide and are happy with your notes, and have the time and need more prep, consume more...

7MTT 3.0 CLI End to End Transition Commands for CBT

Continuing from the previous post, here’s a demonstration via an example of how to use 7MTT 3.0 CLI and PowerShell to transition from 7-Mode to cDOT (lab versions are 8.2.3 and 8.3.2).

In the demonstration, we just transition a standalone volume. To make it more interesting though and to test out some features, we add to the mix vFilers and IPSpaces.

Note: The colour coding has Clustershell ::> green, 7-Mode’s Nodeshell > grey, and PowerShell PS> blue.

Some Initial cDOT Setup

We create an IPSpace for the - to be - transitioned vFiler, with Intercluster LIFs in the IPSpace on each node for SnapMirror replication:


ipspace create -ipspace VF01-IPSPACE

broadcast-domain remove-ports -broadcast-domain Default -ports clu1n1:e0d,clu1n1:e0f,clu1n2:e0d,clu1n2:e0f

broadcast-domain create -broadcast-domain VF01 -ipspace VF01-IPSPACE -mtu 1500 -port clu1n1:e0d,clu1n1:e0f,clu1n2:e0d,clu1n2:e0f

net int create -vserver VF01-IPSPACE -lif vf01-n1-icl -role intercluster -home-node clu1n1 -home-port e0d -address 10.1.5.63 -netmask 255.0.0.0

net int create -vserver VF01-IPSPACE -lif vf01-n2-icl -role intercluster -home-node clu1n2 -home-port e0d -address 10.1.5.64 -netmask 255.0.0.0


Some Initial 7-Mode Setup

We allow snapmirror and create a vFiler VF01 with one volume and a test share:


options snapmirror.access host=10.1.5.63,10.1.5.64

options licensed_feature.multistore.enable on
vol create VF01_VOL0 -s none aggr0 10g
vfiler create VF01 -n -s default-ipspace -i 10.1.7.51 /vol/VF01_VOL0

wrfile -a /etc/hosts 10.1.7.51 VF01 FAS101-e0b
wrfile -a /etc/hosts 10.1.7.61 FAS101-e0c
wrfile -a /etc/hosts 10.1.7.62 FAS101-e0d
ifconfig e0b `hostname`-e0b mediatype auto flowcontrol none mtusize 1500
ifconfig e0c `hostname`-e0c mediatype auto flowcontrol none mtusize 1500
ifconfig e0d `hostname`-e0d mediatype auto flowcontrol none mtusize 1500
wrfile -a /etc/rc ifconfig e0b `hostname`-e0b mediatype auto flowcontrol none mtusize 1500
wrfile -a /etc/rc ifconfig e0c `hostname`-e0c mediatype auto flowcontrol none mtusize 1500
wrfile -a /etc/rc ifconfig e0d `hostname`-e0d mediatype auto flowcontrol none mtusize 1500

vol create VF01_VOL1 -s none aggr0 10g
vfiler add VF01 /vol/VF01_VOL1
vfiler disallow VF01 proto=nfs proto=iscsi proto=rsh proto=ftp

vfiler run VF01 options security.passwd.rules.history 0
vfiler run VF01 setup
vfiler run VF01 cifs setup
vfiler run VF01 cifs shares -add VF01_VOL1 /vol/VF01_VOL1

Step-by-Step Transitioning a Standalone Volume to cDOT with 7MTT 3.0 CLI*
*and a little bit of Clustershell

Note that some of the stuff used below is optional, such as: could have used the default project group; could have pre-created the SVM with management LIF, CIFS server, and CIFS test LIF (my preference); totally optional was the downing the transitioned CIFS server to give it the old AD machine account and NETBIOS name...

Taking it Forward

Further investigations:

- Investigate transitioning primary and secondary 7-Mode volumes
- Create a spreadsheet that allows easy management of multiple projects, and automatic generation of 7MTT CLI commands
- See if my June 2016 7MTT Multiple Job Parser still works with 7MTT 3.0

Saturday, 30 July 2016

7MTT 3.0 is GA and 7MTT 3.0 CLI Commands

7MTT 3.0 General Availability (GA) Release is available for Windows and Linux!

The main thing is support for transitioning to ONTAP 9.0 (from pretty much any version of 7-Mode since 8.0). Also, the CBT and CFT binaries are combined now (the Windows version and GUI is required for CFT.) For further reading check out the 7-Mode Transition Tool 3.0 Documentation and especially the Release Notes for all the new features.

7MTT 3.0 CLI Commands List

The following lists all the 7MTT 3.0 CLI commands. Of course you can use GUI for mostly everything; if you’ve got a lot of transitions to do though, you’ll probably want to investigate automation; hence the listing of CLI commands. Note that this is only a list of the commands, for syntax, from a machine running 7MTT 3.0, in a shell (for a Windows guy like me, that’s PowerShell or Command Prompt), type the command and press enter for the complete help output.
