The documentation for the dbcc page command incorrectly describes the logical parameter.
The correct description for the logical parameter is:
If cache = 1, then value of this parameter is considered as 1 and value passed for pageno parameter is treated as logical page number.
If cache = 0, then value of this parameter is taken as the virtual device number and value passed for pageno parameter will be treated as virtual page number. The virtual device number can be obtained from the master..sysusages table.
