ESXi fails to identify a device as SSD

VMware vSphere ESXi


The message is received when an ESXi host fails to identify a storage device as a Solid State Disk (SSD). Typically, this happens when your storage array does not support an automatic SSD device detection provided by ESXi.


If the ESXi host does not automatically identify a device as SSD, the device cannot be used to allocate space for host cache.


VMware vSphere ESXi 5.1
VMware vSphere ESXi 5.5
VMware vSphere ESXi 5.0


You can use PSA SATP claim rules to tag SSD devices that are not detected automatically. For information on how to tag devices as SSD, see the Tag Devices as SSD topic in the vSphere Storage documentaiton.
