很多服务器都会多块盘或者做了Raid的多个虚拟磁盘，而安装xenserver后，他只会默认挂载第一快盘，也就是安装xenServer系统的那块。
那剩余的其他盘，怎么挂载上去做虚拟机的存储用呢？或者后期新增一块磁盘该如何操作呢？
1、用命令查看下自己的host-uuid
[root@xenserver-testT1 ~]# xe host-list
uuid ( RO) : e0aadd21-2970-48cc-ba17-b322ed42466d
name-label ( RW): xenserver-testT1
name-description ( RW): Default install
2、查看需要挂载的分区
[root@xenserver-testT1 ~]# ls /dev/disk/by-path pci-0000:00:14.0-usb-0:4:1.0-scsi-0:0:0:0 pci-0000:00:1f.2-ata-3.0-part2 pci-0000:00:1f.2-ata-3.0-part5 pci-0000:00:1f.2-ata-4.0-part1 pci-0000:00:1f.2-ata-3.0 pci-0000:00:1f.2-ata-3.0-part3 pci-0000:00:1f.2-ata-3.0-part6 pci-0000:00:1f.2-ata-3.0-part1 pci-0000:00:1f.2-ata-3.0-part4 pci-0000:00:1f.2-ata-4.0
上图中，大家要学会灵活分析磁盘分区，pci-0000:00:14.0-usb-0:4:1.0-scsi-0:0:0:0这个很明显与其他都不同，那它应该就是光驱了，pci-0000:00:1f.2-ata-3.0和后面的part1-part6就是第一块系统盘的所有分区，那剩下pci-0000:00:1f.2-ata-4.0这个就是我们要挂载的第二块磁盘了，后面的part1 就是这个盘的分区。可以通过fdisk验证
[root@xenserver-testT1 ~]# fdisk -l Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes, 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion. Disk /dev/sda: 1000.2 GB, 1000204886016 bytes, 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk label type: gpt # Start End Size Type Name 1 46139392 83888127 18G Microsoft basic 2 8390656 46139391 18G Microsoft basic 3 87033856 1953525134 890G Linux LVM 4 83888128 84936703 512M BIOS boot parti 5 2048 8390655 4G Microsoft basic 6 84936704 87033855 1G Linux swap Disk /dev/mapper/VG_XenStorage--1b0b09c7--d550--d013--166e--2b4223cf3588-MGT: 4 MB, 4194304 bytes, 8192 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/mapper/VG_XenStorage--8f93f732--9d7b--b792--856b--69a3451a7422-MGT: 4 MB, 4194304 bytes, 8192 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes
3、挂载第2块硬盘到系统中，挂载成功会返回新存储的UUID
[root@xenserver-testT1 ~]# xe sr-create type=lvm content-type=user device-config:device=/dev/disk/by-path/pci-0000:00:1f.2-ata-4.0 name-label=‘Disk 2‘ 8f93f732-9d7b-b792-856b-69a3451a7422
替换掉pci-0000:03:00.0-scsi-0:2:1:0为自己的磁盘分区ID即可；Disk 2是第二块盘的存储名称，可以自定义。
4、切换到XenCenter界面可以看到已经多了一个名为Disk 2的本地存储了
