[验证版]vmware虚拟机添加硬盘不重启
作者:快盘下载 人气:遇到该问题，网上扒拉了很多资料，讲的晕乎乎了，至少看了5篇文章都搞定。是我太笨了。具体vmware添加硬盘的过程就不写了。记得是必须选择SCSI或者SATA类型的接口和把虚拟磁盘存储为单个文件。
网上说的<H>、<B>、<T>、<L>这几个我是没理解。只知道H是host，其他的没对应。可能就是这里不理解造成的吧。
还有下边的一句，我更不理解。
[root@localhost ~]# echo "scsi add-single-device 0 0 1 0" > /proc/scsi/scsi
下边这个也不理解。也蒙不对，或许你可以。下边有解释。
echo "- - -" > /sys/class/scsi_host/host2/scan

先查看一下原有的磁盘个数和大小。我原来是两个 sda和sdb。现在添加了个sdc
格式出问题了。将就看吧。

查看一下原有磁盘对应的一些参数，这里我认为是重点
[root@localhost ~]# [root@localhost ~]# cat /proc/scsi/scsi Attached devices: Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: VMware, Model: VMware Virtual S Rev: 1.0 Type: Direct-Access A NSI SCSI reVision: 02 Host: scsi1 Channel: 00 Id: 01 Lun: 00 Vendor: VMware, Model: VMware Virtual S Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 02Host: scsi2 Channel: 00 Id: 00 Lun: 00 Vendor: NECVMWar Model: VMware SATA CD01 Rev: 1.00 Type: CD-ROM ANSI SCSI revision: 05
只知道硬盘是直连的设备所以显示Direct-Access，最下边的是CD-ROM 。硬盘是scsi1，光驱是scsi2
敲黑板，划重点。敲黑板，划重点。敲黑板，划重点
硬盘是scsi1对应的就是host1
光驱是scsi2对应的就是host2
执行 echo "- - -" > /sys/class/scsi_host/host2/scan
[root@localhost ~]# echo "- - -" > /sys/class/scsi_host/host1/scan[root@localhost ~]# [root@localhost ~]#
再次查看。
