So I am no scripting master, my PowerShell knowledge is still something I want to expand. During an install last week I had a number of hosts to setup from scratch, so I decided to do this via PowerCLI, as a lot of the tasks were repetitive. Setting up the vSwitch networking and iSCSI configuration for each host
For those of you new to scripting, I’ve included screenshots to accompany the commands so you can see whats going on in the GUI.
Note: the full code without the breaks is at the end of this post
#Setup which host to target
$VMhost = 'hostname'

I wrote about the latest CBT issue (November edition) a couple of days ago, and as promised by VMware a patch has been released.
Original issue – KB 2136854
Patch to resolve the issue – ESXi600-201511001 (2137545)
Note: Before applying this patch on HP Proliant Gen 9 servers, see VMware ESXi 6.0 host fails to detect local disk after patching or applying Update 1 on HP Proliant Gen 9 servers (2120539).
Cheers VMware, lets hope this is the last of the CBT issues!!!

So here we are again, rounding the year off with yet another change block tracking warning.
I’ve written posts previously on the CBT bugs found in 5.5 and below and those found when vSphere 6.0 was released into the wild.
Basically it is the same as last time, the wrong sectors of data locations are returned by CBT when requested by your backup software. Meaning it targets the wrong data to backup.
Here is the official VMware KB 2136854. Which describes the following;
When running virtual machine backups which utilize Changed Block Tracking (CBT) in ESXi 6.0, you experience these symptoms:
- The CBT API call QueryDiskChangedAreas() API call can sometimes return incorrect changed sectors, which results in inconsistent incremental virtual machine backups.
- Inconsistent virtual machine backups
All incremental backups which utilize CBT are potentially affected.
Anton Gostev, Veeam, has released a lengthy email to Veeam customers and Gostev lovers stating the following (you can follow the veeam forum post here); Continue reading Yet again, ESXi 6.0, CBT issues #vDM30in30
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.
