NetApp LUN block size

While working with Zerto, there was a requirement to ensure NetApp LUN size is a 512 block size.

So, how do you find out the block size of a NetApp LUN in 7 mode?

Here is a command for your rescue.

'LUN SHOW -V'

Commvault restore 0kb files

Hello World,

Hope you are in peace with your creatures and plastics. 

This week while restoring guest files from a deduplication-enabled  Commvault backup of a virtual machine running on Windows 2012 or later, a file-level restore operation completes successfully but creates only stub files (0kb in size). 

Commvault support recommended that the proxy/media agent used for restore has window de-duplication feature installed (using server manager). Once the deduplication feature was installed on the media agent and an additional setting (nEnforceLiveBrowse) was added to the media agent, the restore of files completed successfully. Happy days!

So next time you have this issue, enable windows deduplication on the media agent/proxy and configure the additional setting.

Webconsole report : Unable to edit email recipient

Hello World,

Just last week, I ran into a weird problem where Commvault webconsole would not allow me to update the email recipients of a webconsole report.

After much clicking and scratching, it was found that using a browser other than internet explorer fixes the issue. Chrome worked well for me.
