Yesterday we deployed a few new Cisco UCS B200 M3 host into our blade environment. We would like to extend our computing capacity, formally we use VMware ESXi hypervisor. We have tried create new host profile from one ESXi host, when we got this error message that you can see at below.
I was carfully, before a ran this command I had vmotioned all VMs from this host!!
“Extract Host Profile” operation faild for entity with the following error message.
A general system error occurred:
Value specified is out of range. Range: 1 to 256
Value specified is out of range. Range: 1 to 16″
I typed error message into the Google search, and short time I watched this KB Article: https://kb.vmware.com/kb/2070031 which solved that. In the list appeared this device whitch didn’t have any information. I cheked our ESXi host can’t see this device on GUI, so I continued the steps from the article.

After that I ran this commands, the host profile created successfully without any interruption, so that was online operation, no effected to our environement.
