From the new window, click on New alert policy. Now you’ll want to switch over to the acli prompt. The quiesce operation pauses or alters the state of running processes on the virtual machine, especially processes that might modify information stored on the disk during a revert operation. If you switch to the acropolis prompt you’ll be able to make use of handy tab completion acliThis will give you the acropolis prompt. With VMware vSphere you needed to do this with PowerCLI or use the excellent RVTools.In Nutanix Prism you can (to my knowledge) only see the snapshots when opening the virtual machine … To quiesce the virtual machine files, verify that the virtual machine is powered on and that VMware Tools is installed.

This is not possible with hypervisor-based snapshots today. Run apps and workloads on a single platform with unparalleled availability, performance, and simplicity. Required fields are marked *. In an earlier post I described how Nutanix clones can speed up deployment workflows for MongoDB replica sets. Without the ability to track changes snapshots will be one of many features that will not be possible. If additional availability is required then we can clone “blank” gold image VMs and form a new replica set. You can do this as follows …. For example, if you have a special purpose configuration that requires you to use an independent disk, you must power off the virtual machine before taking a snapshot.
