When that is done, then you must stop and flush all I/O, and remove all operating system references to the device, as described below.  If this is a multipath device then you must do this for the multipath psuedo device, and each of the identifiers that represent a path to the device.

How can I find out if I have a 64-bit capable CPU

Questions - Linux
 Problem

 

You want to know if an x86 system is capable of running 64-bit software.

 Resolution

 

There are two primary modes of operation of the microprocessor architecture: Long mode (lm) and Legacy mode. Long mode is used by 64-bit operating systems. It combines the processor's native 64-bit mode and a 32-bit/16-bit compatibility mode. Under this mode, 64-bit, 32-bit and 16-bit applications may be supported. Legacy mode is only used by 16-bit and 32-bit operating systems.
