Installation guide

Change the SCSI Controller or SCSI Bus Sharing Configuration
You can set the SCSI controller type and the type of SCSI bus sharing for a virtual machine. SCSI bus sharing
can set to none, virtual, or physical sharing types.
You can change the SCSI controller configuration for a virtual machine on an ESX/ESXi host only.
CAUTION Changing the SCSI controller type might result in a virtual machine boot failure.
You can also specify whether the SCSI bus is shared. Depending on the type of sharing, virtual machines can
access the same virtual disk simultaneously on the same server or any server.
Procedure
1 In the Virtual Machine Properties Editor, click the Hardware tab.
2 Click the appropriate SCSI Controller in the Hardware list.
3 Under SCSI Controller Type, click Change Type.
4 Select the SCSI controller type.
5 Click OK.
6 Select the type of sharing in the SCSI Bus Sharing list:
Option Description
None
Virtual disks cannot be shared by other virtual machines.
Virtual
Virtual disks can be shared by virtual machines on same server.
Physical
Virtual disks can be shared by virtual machines on any server.
7 Click OK to save your changes and close the dialog box.
Change the Serial Port Configuration
You can use a physical serial port, an output file, or a named pipe to configure a serial port for a virtual machine.
Procedure
1 In the Virtual Machine Properties Editor, click the Hardware tab.
2 Click the appropriate Serial port in the Hardware list.
3 If you selected Use physical serial port on the host, use the drop-down menu to select the port on the
host computer that you want to use for this serial connection.
4 If you selected Use output file, browse to the location of the file on the host that you want to use to store
the output of the virtual serial port.
5 If you selected Use named pipe, use the default pipe name or enter another pipe name of your choice in
the Pipe Name list.
For a serial pipe for a virtual machine on an ESX host for Linux, enter /tmp/<socket> or another UNIX
socket name of your choice.
Then decide whether you are connecting two virtual machines or connecting a virtual machine to an
application on the host.
