-When you deploy an Azure Arc enabled SQL managed instance, you can configure the size of the persistent volume (PV) for `data`, `logs`, `datalogs`, and `backups`. The deployment creates these volumes based on the values set by parameters `--volume-size-data`, `--volume-size-logs`, `--volume-size-datalogs`, and `--volume-size-backups`. When these volumes become full, you will need to resize the `PersistentVolumes`. Azure Arc enabled SQL Managed Instance is deployed as part of a `Statefulsets` for both General Purpose or Business Critical service tiers. Kubernetes supports automatic resizing for persistent volumes but not for volumes attached to `StatefulSets`.

 During the patching of `PersistentVolumeClaim`, the status of the persistent volume claim will likely change from: `Attached` to `Resizing` to `FileSystemResizePending` to `Attached`. The exact states will depend on the storage provisioner.

 > Ensure the managed instance is in a healthy state before you proceed. Run `kubectl get sqlmi -n <namespace>` and check the status of the managed instance.

 There is one `StatefulSet` deployed for each Arc SQL MI. The number of replicas in the `StatefulSet` is equal to the number of replicas in the Arc SQL MI. For General Purpose service tier, this is 1. For Business Critical service tier it could be 1, 2 or 3 depending on how many replicas were specified. Run the below command to get the number of `StatefulSet` replicas if you have a Business Critical instance.
