PowerCLI – Setup Host networking and storage ready for ISCSI LUNs

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'

Yet again, ESXi 6.0, CBT issues #vDM30in30

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.

So whats the issue this time?

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

Deploy a Cisco UCS system – Part 4 – Upgrading the Firmware

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.

Covered in this post;

  • Pre-reqs
  • Getting the Firmware
  • Upload firmware into UCS Manager
  • Upgrading UCS Manager
  • Upgrading the Fabric Interconnects
  • Upgrading the Blade Servers
Pre-Reqs
