az disk create
Is your feature request related to a problem? Please describe.
Whenever the availability or connectivity between a VM and the associated Azure managed disk is affected for more than 180 seconds, the Azure platform performs a forced shutdown of the VMs. The VMs are automatically powered back on after storage connectivity has been restored.
Disk availability policy is a new disk property that enables customers to avoid rebooting the VM when a data disk experiences an issue. Users can leverage this feature to opt into taking the data disk offline on an IO timeout exceeding 180 seconds without disrupting the running state of the VM. While the disk is offline, the Azure platform will detach the disk and any IO to that disk will return an error. Once the underlying platform issue is resolved, Azure will automatically reattach the disk, bring the disk back online, and make it available to use for the VM.
Describe the solution you'd like
a. Add properties.availabilityPolicy.actionOnDiskDelay to CLI
i. “AutomaticReattach” – Set the disk availability policy
ii. “None” – Remove the disk availability policy. (Default)
