Citrix released the new version of the Xen. Server 7 platform. For installation follow Fresh Installation of Xen. Server 7. Add Xenserver Storage Repository Part 4. Xen. Server introduces several new terms to the traditional storage terminology list. While understanding the concepts are always important when working with any IT system, storage isnt nearly as crucial as the prior article covering networking concepts. However, this article will still take the time to explain and attempt to clarify these storage concepts. The first thing to remember with Xen. Server storage is that we have storage for the actual Xen. Server host and then we also have storage for the guest or virtual machines that will run on the Xen. Server host. Conceptually this is simple to grasp but managing it can be a daunting task if the administrator is unfamiliar with the purposes of each of the storage aspects. The first term is known as SR or Storage Repository. This is arguably the most important term in Xen. Server storage as it represents the physical medium to which virtual machine disks will be stored and retrieved. Storage repositories can be any of several different types of storage systems including, local storage attached physically to the Xen. Server host, i. SCSIFibre Channel LUN, NFS Network File Shares, or storage on a DellNet. App storage appliance. Storage repositories can be shared or dedicated and can support numerous useful features such as fast cloning, sparse allocation storage provisioned as the virtual machine needs it, and re sizable virtual disk images more on these later. Storage repositories, SR, are logically connected to a Xen. Server host with what is known as a Physical Block Device, more commonly referenced as PBD. The PBD is simply a reference to a storage location. These PBD objects can be plugged into a Xen. Server host to allow that host to readwrite information to that storage repository. The purpose of Storage repositories is primarily to store the virtual machine Virtual Disk Image VDI files. VDI files are spots on a SR that have been allocated to hold operating system and other files for virtual machine running on the Xen. Server host. VDI files can be any of several different types. The type is determine by the type of storage repository. Common VDI types in Xen. Server are Logical Volumes LV managed by Logical Volume Manager, Virtual Hard Disk VHD, or they can be Logical Unit Numbers LUN on a Dell or Net. App storage device. Note This article will be using LUNs on a Dell storage device. These VDI files are connected to virtual machines logically through an object known as a Virtual Block Device, commonly referenced as VBD. These VBD objects can be attached to virtual guests which then allows the guest machine to access the data stored in that particular VDI on a respective SR. Much like networking in Xen. Server, reading about storage is one thing but being able to see the relationship amongst each of these items often solidifies the concepts. The common diagrams used to represent Xen. Server storage concepts often confuses newer people as the diagrams are often read in a linear fashion. Below is one such image borrowed from Citrix. Citrix Xen. Server Storage Concepts. Many individuals read this linearly from left to right thinking that each part is a separate physical device. This isnt the case and often leads to much confusion about how Xen. Server storage works. The graphic below attempts to explain the concepts in a less linear but more pragmatic manner. Xen. Server Storage Works. Hopefully the above graphic doesnt further confuse individuals about Xen. Server storage. The second image is an attempt to show the logical connections PBD and VBD that are used to connect Xen. Servers and guests to remote storage over one actual network connection. With the conceptualization out of the way the configuration can begin. Recalling from the first article in this series, this guide is using a Dell PS5. E i. SCSI storage device for the storage of the virtual machine guests disks. This guide will not be walking through configuration of the Dell i. SCSI device. System Configuration Xen. Server 6. 5 installed and patched Part 1 of seriesDell PS5. E i. SCSI device other i. SCSI devices can be used just substitute environment information where needed. Xen. Server network interfaces configured Part 3 of series. SCSI device and Xen. Server can logically see each other via ping utility. CIFS SAMBA Server running and hosting a share of CD ISO files not required but very useful. Citrix Xen. Server Storage Repository Creation. This first process will go through the steps to create a software i. SCSI initiator from the Xen. Server host to the Dell PS5. E. This particular LUN uses Challenge Handshake Authentication Protocol CHAP to restrict access to the i. SCSI volume to certain authorized parties. To create the storage repository, a traditional xe command will occur. The proper i. SCSI information needs to be obtained before creating the Storage Repository. Passing the sr probe parameter to the xe utility will instruct the Xen. Server to query a storage device for the i. SCSI IQN i. SCSI Qualified Name. The first command will look intense at first but its not as bad as it looks. X. X. X. X device config chapusertecmint device config chappasswordtecmintchap. This first command is needed to gather the SCSI IQN for the Storage repository configuration. Before moving on, lets take a look at all the parts of this command. Used to query the i. SCSI device for information about the volume created for this Xen. Server host. type Used to tell the Xen. Server the storage repository type. This will vary depending on what system is being used. How To View Wmf Files On Windows 7 As Thumbnails here. Due to the usage of the Dell PS5. SCSI is used in this command. Be sure to modify to fit the storage device type. Used to tell the Xen. Server what i. SCSI device to query by IP address. This is used to authenticate to the i. SCSI device. In this example an i. SCSI volume has been created previously for the user tecmint. By sending the user name and password in this command, the i. SCSI device will respond back with the necessary information to finish creating the storage repository. This is the password for the above CHAP user name. Once the command is entered and submitted, the Xen. Server will attempt to log into the i. SCSI device and will return some information needed in order to actually add this i. SCSI device as a Storage Repository. Below is what the test system returned from this command. Error code SRBACKENDFAILURE9. Error parameters, The SCSIid parameter is missing or incorrect, lt IPAddress. IPAddress. Target. IQN. iqn. Target. IQN. lt IPAddress. IPAddress. lt Target.
