Description:- Failed to take a snapshot of a VMware Virtual Machine using CA ARCserve Central Host-Based VM Backup for a Machine which has Disks configured as Independent disks.
Solution:- This is a limitation from VMware as well, the documentation of VMware clearly says that we cannot take a snapshot of a Virtual Machine which is configured as Independent Disks as a result if a Snapshot command is triggered all the Writers in the Virtual Machine goes into Failed State. The result is the same even though you trigger a Backup from CA ARCserve Central Host-Based VM Backup or from Vsphere Client while taking a quiesced snapshot.
-Use CA ARCserve D2D to back up the VM. Install it inside the VM.
Refer to the below mentioned kb articles from VMware which clearly explains the same.
Refer to the resolution section which clearly explains the steps, but before changing anything please consult the Administrator or VMware.
