VMware GSX Server 2.5.2Features | Documentation | Knowledge Base | Discussion Forums GSX Server permits the sharing of plain disks with multiple virtual machines running on the same host, provided the disk in question is a SCSI disk. Note: Although virtual and raw disks can be used with SCSI reservation, such use is considered experimental. Only the use of plain disks is fully supported with SCSI reservation. To create a plain disk, see Adding Plain Disks to a Virtual Machine. When the disk is shared, all virtual machines connected to the disk are able to write to the disk concurrently with the SCSI reservation protocol. This feature is advanced and should only be used if you are familiar with SCSI in general and the SCSI reservation protocol in particular. In addition, clustering software must be installed in each virtual machine that intends to share a SCSI disk. Enabling SCSI reservation in and of itself does not automatically mean that a running virtual machine is a participant in the SCSI reservation protocol. The following sections describe how to use SCSI reservation to share disks among multiple virtual machines. |
