很多服務器都會多塊盤或者做了Raid的多個虛擬磁盤，而安裝xenserver後，他只會默認掛載第一快盤，也就是安裝xenServer系統的那塊。
那剩餘的其他盤，怎麼掛載上去做虛擬機的存儲用呢？或者後期新增一塊磁盤該如何操作呢？
1、用命令查看下自己的host-uuid
[root@xenserver-10 ~]# xe host-list
uuid ( RO) : dca60990-98c3-4f10-b05d-aee9138778f7
name-label ( RW): xenserver-8.239
name-description ( RW): Default install
2、查看所有硬盤了的id
[root@xenserver-10 ~]# ls -l /dev/disk/by-id/
total 0
lrwxrwxrwx 1 root root 10 Oct 24 12:52 dm-name-VG_XenStorage--1d5302ea--598a--8acd--5be5--b67e3a142160-MGT -> ../../dm-0
lrwxrwxrwx 1 root root 10 Oct 24 12:52 dm-uuid-LVM-67dHwk1JS4179AxhDbOKqkOue2zwvABRX6ilOR9xT2sUseuVJUfBXa36HKrO726G -> ../../dm-0
lrwxrwxrwx 1 root root 9 Oct 24 12:51 scsi-364cd98f09abc4b002541c7e30460debf -> ../../sda
lrwxrwxrwx 1 root root 10 Oct 24 12:51 scsi-364cd98f09abc4b002541c7e30460debf-part1 -> ../../sda1
lrwxrwxrwx 1 root root 10 Oct 24 12:51 scsi-364cd98f09abc4b002541c7e30460debf-part2 -> ../../sda2

lrwxrwxrwx 1 root root 10 Oct 24 12:51 scsi-364cd98f09abc4b002541c7e30460debf-part5 -> ../../sda5
lrwxrwxrwx 1 root root 10 Oct 24 12:51 scsi-364cd98f09abc4b002541c7e30460debf-part6 -> ../../sda6
lrwxrwxrwx 1 root root 9 Feb 6 10:51 scsi-364cd98f09abc4b002541c7ef0511f4de -> ../../sdb
lrwxrwxrwx 1 root root 9 Oct 24 12:51 wwn-0x64cd98f09abc4b002541c7e30460debf -> ../../sda
lrwxrwxrwx 1 root root 10 Oct 24 12:51 wwn-0x64cd98f09abc4b002541c7e30460debf-part1 -> ../../sda1
lrwxrwxrwx 1 root root 10 Oct 24 12:51 wwn-0x64cd98f09abc4b002541c7e30460debf-part2 -> ../../sda2

lrwxrwxrwx 1 root root 10 Oct 24 12:51 wwn-0x64cd98f09abc4b002541c7e30460debf-part4 -> ../../sda4
lrwxrwxrwx 1 root root 10 Oct 24 12:51 wwn-0x64cd98f09abc4b002541c7e30460debf-part5 -> ../../sda5
lrwxrwxrwx 1 root root 10 Oct 24 12:51 wwn-0x64cd98f09abc4b002541c7e30460debf-part6 -> ../../sda6
lrwxrwxrwx 1 root root 9 Feb 6 10:51 wwn-0x64cd98f09abc4b002541c7ef0511f4de -> ../../sdb
3、查看需要掛載的分區
[root@xenserver-10 ~]# ls -l /dev/disk/by-path/
total 0
lrwxrwxrwx 1 root root 9 Oct 24 12:51 pci-0000:1a:00.0-scsi-0:2:0:0 -> ../../sda
lrwxrwxrwx 1 root root 10 Oct 24 12:51 pci-0000:1a:00.0-scsi-0:2:0:0-part1 -> ../../sda1
lrwxrwxrwx 1 root root 10 Oct 24 12:51 pci-0000:1a:00.0-scsi-0:2:0:0-part2 -> ../../sda2
lrwxrwxrwx 1 root root 10 Oct 24 12:51 pci-0000:1a:00.0-scsi-0:2:0:0-part3 -> ../../sda3
lrwxrwxrwx 1 root root 10 Oct 24 12:51 pci-0000:1a:00.0-scsi-0:2:0:0-part4 -> ../../sda4
lrwxrwxrwx 1 root root 10 Oct 24 12:51 pci-0000:1a:00.0-scsi-0:2:0:0-part5 -> ../../sda5
lrwxrwxrwx 1 root root 10 Oct 24 12:51 pci-0000:1a:00.0-scsi-0:2:0:0-part6 -> ../../sda6
lrwxrwxrwx 1 root root 9 Feb 6 10:51 pci-0000:1a:00.0-scsi-0:2:1:0 -> ../../sdb
4、掛載第2塊硬盤到系統中，掛載成功會返回新存儲的UUID
[root@xenserver-10 ~]# xe sr-create type=lvm content-type=user device-config:device=/dev/disk/by-path/pci-0000:1a:00.0-scsi-0:2:1:0 name-label="Disk 2"
40bf63b0-cb28-9a21-1395-99e3be77e353
ssh鏈接更改xenserver管理ip
[root@xenserver-233 ~]# xe pif-list
