I have a HP ML370 G6 server.
I have two LTO-4 tape drives connected to two SCSI controllers.
I discovered that the SCSI controllers installed were incorrect.
We decided to upgrade one tape to LTO-5.
So I removed the incorrect SCSI controllers and installed a new SCSI controller and a SAS controller for the LTO-5.
The new controllers do not appear on the device list when I run the VSphere client.
How do I get ESXi to recognise these new controllers ?
