You need to confirm the deployment mode of the ACOS cluster before mounting the physical disk. Different deployment modes allow mounting different physical disks:
When the ACOS cluster adopts the non-tiered storage, only SSDs are allowed to be mounted.
When the ACOS cluster adopts the tiered storage, and the cache and data share all physical disks:
When the ACOS cluster adopts the tiered storage and the cache disk and data disk are deployed independently, both SSDs and HDDs can be mounted, but HDDs can only be mounted as data disks.
Risk warning
Mounting a physical disk will clear all data on that physical disk. Operate with caution.
