如果在系统开启之前的硬盘信息,可以通过 fdisk -l查看。
如果系统启动之后,再添加的硬盘信息可能通过 fdisk -l查询不到。
此时重新扫面:
[root@localhost /]# echo "- - - "> /sys/class/scsi_host/host0/scan
[root@localhost /]# echo "- - - "> /sys/class/scsi_host/host1/scan
[root@localhost /]# echo "- - - "> /sys/class/scsi_host/host2/scan
再查看:
bash
[root@localhost /]# fdisk -l
