feature announcement

Azure is introducing per-disk resiliency in public preview for its Virtual Machines, providing an alternative to the default VM recovery mechanism. This opt-in feature allows individual data disks to detach and go offline while the VM and its remaining disks continue operation, automatically reattaching when connectivity is restored. It is designed for applications tolerant to temporary loss of a single data disk, such as clustered workloads or VMs with backup disks, reducing downtime for the primary workload. The feature is currently available in select regions, while OS disks will continue to use the existing VM shutdown recovery behavior.

Features (1)
  • Opt-in Per-Disk Resiliency for Azure VM Data Disks

    Azure now offers per-disk resiliency, allowing a single data disk to temporarily detach and go offline without shutting down the entire VM. This feature automatically brings the disk back online once connectivity is restored, with I/Os to the offline disk returning errors. It is an opt-in setting for each Azure Managed Disk, while OS disks continue to use the default VM shutdown and power-on recovery.
