= Enabling the PersistentReservation feature gate
|
|
|
|
[role="_abstract"]
|
|
You can enable the SCSI `persistentReservation` feature gate and allow a LUN-backed block mode virtual machine (VM) disk to be shared among multiple virtual machines.
|
|
|
|
The `persistentReservation` feature gate is disabled by default. You can enable the `persistentReservation` feature gate by using the web console or the command line.

.Prerequisites
|
|
|
|
* Cluster administrator privileges are required.
|
|
* The volume access mode `ReadWriteMany` (RWX) is required if the VMs that are sharing disks are running on different nodes. If the VMs that are sharing disks are running on the same node, the `ReadWriteOnce` (RWO) volume access mode is sufficient.
|
|
* The storage provider must support a Container Storage Interface (CSI) driver that uses Fibre Channel (FC), Fibre Channel over Ethernet (FCoE), or iSCSI storage protocols.
