reboot server

[ferexderta]

a virtual server restart is happening. microsoft says that this was caused by lsi.sas.sys, LSI_SAS driver . how to find LSI_SAS driver . what is this LSI_SAS driver ? Is the driver installed when I install vmtools?

It's the driver for your virtual SCSI controller.

how to reinstall it or update. Microsoft says old this is an old driver and the problem may be due to it says.  I use ESXi 6.5, Windows 2012 r2, VMware Tools: Running, version:10279 and also SCSI controller LSI Logic SAS. should I use VMware Paravirtual. should I install a driver on windows?

[jburen · Accepted solution]

Personally I prefer the Paravirtual Controller. For this to work follow these steps:

1. Update VMware Tools on your VM.
2. Add an extra small disk to your VM with the Paravirtual Controller.
3. Reboot the VM so the new driver can be loaded. Make sure you see the extra disk in the guest OS.
4. Shutdown the VM and change the controller of your original disk(s).
5. Also remove the extra disk.
6. Boot the VM.

I understand what you say, but I want to know what LSI Logic SAS means to update. update to Paravirtual Controller or reinstall vmtools on windows server?

Trying to update the VMware Tools in order to update the driver is probably the easiest thing to do. So update VMware Tools and try to update the driver inside the guest OS. But as stated before I would upgrade the controller to the paravirtual controller.

When I install VMWare tools, the driver in OS ( windows ) is automatically updated. I don't need to install manual driver for windows. right?

[jburen]

I don't think you need to update the driver manually but you can always point the device to the driver in the VMware Tools folder.
