# ESXi host Disk.MaxLUN advanced setting.

# Some customer environments relied on lower legacy default value to avoid PDL errors with certain vendor SAN management LUNs exposed at a higher number.

# The test value's data type, to help with conversion: bool/string/int

$Type = 'int'

# The command(s) to pull the actual value for comparison

# $Object will scope to the folder this test is in (Cluster, Host, etc.)
