To add additional hard disk in xenserver

When a new internal hard drive is installed on a XenServer to work as a new local storage repository, it is not immediately available to the XenServer Console. This article describes how to add an additional hard drive in XenServer.


To Install a hard drive on a XenServer

At first, Switch On the Xenserver
add-new-hard-drive-as-local-storage-repository-in-XenServer-console-Switch-On-Xenserver-status-display
Open Xencenter tool and connect to Xenserver.
add-new-hard-drive-as-local-storage-repository-in-XenServer-console-Open-Xencenter
Check the available hard disk in Storage section.
add-new-hard-drive-as-local-storage-repository-in-XenServer-console-Storage-section
Here, local storage is my default storage. Select “ console” in xencenter-server menu tab.

Press enter to login into Xenserver
add-new-hard-drive-as-local-storage-repository-in-XenServer-console-login

Run the following command to display the installed disks.

[root@xenSR-linuxhelp ~]# fdisk -l

Disk /dev/sda: 107.3 GB, 107374182400 bytes
255 heads, 63 sectors/track, 13054 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sda doesn' t contain a valid partition table

WARNING: GPT (GUID Partition Table) detected on ' /dev/sdb' ! The util fdisk doesn' t support GPT. Use GNU Parted.

Disk /dev/sdb: 42.9 GB, 42949672960 bytes
256 heads, 63 sectors/track, 5201 cylinders
Units = cylinders of 16128 * 512 = 8257536 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1        5202    41943039+  ee  EFI GPT

“ /dev/sdb1” is my default hard disk. Here my Xenserver take new hard disk as “ /dev/sda”



To check host uuid

[root@xenSR-linuxhelp ~]# xe host-list
uuid ( RO)                : 1b2265f8-06fb-4980-8415-371e627efefb
          name-label ( RW): xenSR-linuxhelp
    name-description ( RW): Default install of XenServer

Run the following command from the command line interface.

[root@xenSR-linuxhelp ~]# xe sr-create content-type=user device-config:device=/dev/sda host-uuid=1b2265f8-06fb-4980-8415-371e627efefb name-label=" local-storage2"  shared=false type=ext
4226d65a-e2cf-f7aa-9f30-d828df5b6879

Now, the installed hard drive is visible in the XenServer Console.

add-new-hard-drive-as-local-storage-repository-in-XenServer-console-hard-drive-visible
Click “ storage” in menu option and check the new hardisk.
add-new-hard-drive-as-local-storage-repository-in-XenServer-console-local-storage2
Here “ local-storage2” is successfully added.

Q

By making UnRaid a VM does it still allow the ability just to drop the bzroot and bzimage files when upgrades are released?

A

yes it does, but you will need to remember to drop the files onto VHD as well as on the USB stick the issue is that Hyper-visors do not support booting VM from USB sticks so you need a VHD

Q

Are the onboard SATA ports of the motherboard left for XenServer operation, and the UnRaid hard drives all placed on Expansion cards placed on the pcie? 

A

this is usually the case for VM setup. the reason being that you would want UnRaid full control of drive controller and HDD attached to it
