    Hello IT-CA,

    Can you please let us know which disk you are using. Currently, only Ultra Disks, Premium SSD v2, Premium SSD, and Standard SSDs can be used as a shared disk.

    Shared disks have general limitations that apply to all shared disks, regardless of disk type. Apart from this there are some additional limitations that only apply to specific types of shared disks. 

    For reference: https://learn.microsoft.com/en-us/azure/virtual-machines/disks-shared-enable?tabs=azure-portal#limitations

    Kindly let us know if you have any further queries. I’m happy to assist you further.
