大家好，我是新手，用ioscan命令如何显示没被vg使用的磁盘信息？

Answer 1

ioscan和vgdisplay对比不就行了吗？

Answer 2

ioscan是不能显示有没有给vg使用的,只能显示当前的硬件状态,不包括vg信息.
如果要看vg信息可以用ll /dev/*/group , vgdisplay vg**,但对应ioscan -Cc disk.

Answer 3

我的意思是从存储划分过来的盘，没有被vg使用的盘不让它显示出来，还请指教！

    ioscan(1M)                                                       ioscan(1M)

NAME
      ioscan - scan I/O system

SYNOPSIS
      /usr/sbin/ioscan [-k|-u] [-e] [-d driver|-C class] [-I instance]
           [-H hw_path] [-f[-n]|-F[-n]] [devfile]

      /usr/sbin/ioscan -M driver -H hw_path [-I instance]

      /usr/sbin/ioscan -t

DESCRIPTION
      ioscan scans system hardware, usable I/O system devices, or kernel I/O
      system data structures as appropriate, and lists the results.  For
      each hardware module on the system, ioscan displays by default the
      hardware path to the hardware module, the class of the hardware
      module, and a brief description.

      By default, ioscan scans the system and lists all reportable hardware
      found.  The types of hardware reported include processors, memory,
      interface cards and I/O devices.  Scanning the hardware may cause
      drivers to be unbound and others bound in their place in order to
      match actual system hardware.  Entities that cannot be scanned are not
      listed.

      In the second form shown, ioscan forces the specified software driver
      into the kernel I/O system at the given hardware path and forces
      software driver to be bound.  This can be used to make the system
      recognize a device that cannot be recognized automatically; for
      example, because it has not yet been connected to the system, does not
      support autoconfiguration, or because diagnostics need to be run on a
