Storage Basics

I have been concentrating on storage for some time now and if you are trying to understand storage basis, here is a great list of documents covered by Josh Townsend  in his blog.

I was lucky to hit this early than many of you wanted to, I hope this helps you to get a clear understanding on the basic ground of storage.  Josh has smartly split down storage in VIII different units starting from basic to advanced concept, which makes it very easy to understand.  I have added topic and link to respective portion in Josh blog. I am sure you will find it very useful.

Thanks to Josh for his contribution.

How to Disable Automatic Host Registration

When you use EMC CLARiiON or Invista arrays for storage, the hosts must register with the arrays. ESX/ESXi

Performs automatic host registration by sending the host’s name and IP address to the array. If you prefer to

perform manual registration by using storage management software, turn off the ESX/ESXi auto-registration feature.

Procedure

1 In the vSphere Client, select the host in the inventory panel.

2 Click the Configuration tab and select Advanced Settings under Software.

3 Select Disk in the left panel and scroll down to Disk.EnableNaviReg on the right.

4 Change the default value to 0.

5 Reboot the host for the changes to take effect.

This action disables the automatic host registration enabled by default.
