“Invalid configuration for device 0” when removing a virtual disk

I tried to remove RDM disk from VM but it failed with an error “invalid configuration for device 0”. I have usually seen this message related with vNIC but this time it was the disk.

After some searching I found a solution – I changed SCSI ID from 0:1 to 0:2 for the disk I wanted to remove. After that remove operation worked.

Extended my home lab

I’ve recently extended my home lab with additional capacity. In addition to my Windows Server + VMware Workstation (info here) I’ve added refurbished HPE DL380 G7 server with following configuration:

1 x Intel Xeon Processor X5650 2.66Ghz
96GB RAM
1TB HDD
will add SSD in the future

The added server is running VMWare ESXi 6.7. It hosts vCenter 6.7 appliance and also few virtual ESXi 6.7 instances. HPE G7 series servers are not officially supported by VMWare to run ESXi 6.7 but it seems to be working for now.

I found my refurbished HPE G7 server from Ebay.

The required VMWare Tools ISO image does not exist or is inaccessible.

Recently I deployed some VMs from an template which I had created some years ago. When I tried to update VMWare Tools I received an error “The required VMWare Tools ISO image does not exist or is inaccessible.”

After some digging around in Google I found a thread in VMware forums which also pointed me to a right direction. I had set following advanced option in VM configuration –¬†isolation.tools.autoInstall.disable = TRUE.

To allow VMWare Tools ISO mounting I set the value from TRUE to FALSE.
