Overview With the 64-bit open-source Xen hypervisor at its core, Citrix® XenServer Dell™ Edition is a powerful virtualization solution that enables efficient resource consolidation, utilization, dynamic provisioning, and integrated systems management. XenServer Dell Edition has a small footprint and is optimized to run from an internal flash storage in Dell PowerEdge™ systems. For added flexibility, you can also install XenServer Dell Edition on a hard disk drive.
• High Availability — XenServer Dell Edition supports several features to guarantee service uptime in the event of infrastructure failure. You can configure resource pools for automated high availability. For example, in the case of individual host failures, you can move VMs running on the failed hosts to the next available system in the resource pool and restart them.
• Improved XenServer updates — To improve reliability of software upgrades, the XenServer Dell Edition image contains a primary and secondary copy of the XenServer file system. Any time an update is applied, only the secondary copy is updated, leaving the primary copy in a known good state. The secondary copy now becomes the primary image. You can update the XenServer host by using the XenServer local console or XenCenter. NOTE: You can upgrade the XenServer host to release 5.0.

Systems Management Using Dell OpenManage
Configuring Storage Local Storage Repository (SR) Configuration A local storage repository (SR) is a storage for virtual machines (VMs) on the local hard disk drives of a Dell™ PowerEdge™ system. Depending on the storage configuration of the server, a local SR may be automatically created during the Citrix® XenServer® Dell™ Edition boot. A local SR is automatically created on the system if the local storage volume has a Dell utility partition (UP) or a Dell UP and a Dell No Operating System (NOS) partition.
Creating a Volume Using Dell OpenManage Server Administrator Storage Management You can create a new storage volume or virtual disk on the disks attached to Dell PowerEdge RAID Controller(PERC) or Serial Attached SCSI (SAS) storage controllers, as illustrated in Figure 5-1 using OpenManage Server Administrator Storage Management. To create a new virtual disk, follow the steps in the Dell OpenManage Server Administrator Storage Management User's Guide available on the Dell Support website at support.dell.

3 From the Mappings tab in the Storage Array Profile window, note the controller number which owns the newly-created volume. If you wish to provide the XenServer hosts access to more than one volume, ensure all the volumes are on the same MD3000i controller. To change the controller that owns a volume, in the MDSM interface: a Go to Modify→ Change Virtual Disk Ownership/Preferred Path. b Select the appropriate Disk Group and the virtual disk.
Figure 5-17. iSCSI Initiator Window 7 Host Group configuration starts from the Configure Host Access (Manual) - Specify Host Group screen. If provisioning storage as shared storage for a XenServer pool, a host group must be defined so the MD3000i storage subsystem has a configured iSCSI path to each of the hosts.
Figure 5-18. Modular Disk Storage Manager – Configure Tab 10 Select Finish to confirm the new host definition. This initiates the wizard configuration of the new host. 11 On completion, select Yes to proceed to the next host you wish to configure, or select No to end the configuration wizard. 12 Return to XenCenter and create a new SR by connecting to the desired XenServer host and clicking on its Storage tab. 13 Click Add, choose the iSCSI radio button for Virtual disk storage, and click Next.
Dell EqualLogic PS Series Dell EqualLogic PS Series iSCSI arrays simplify storage deployment by offering high performance, reliability, intelligent automation, and seamless virtualization of a single pool of storage. The foundation of an EqualLogic storage array is a PS Series group — an iSCSI SAN including one or more PS Series storage array members connected to an IP network and managed as a single system.
Reference Configurations • Basic Configuration — This configuration contains XenServer hosts, each with a NIC for iSCSI connectivity and a PS Series enclosure with redundant RAID controllers. Each host's NIC is connected to an Ethernet switch, and the Ethernet switch has connections to all six ports on the RAID controllers. See Figure 5-19 for an illustration of this configuration. Storage Repositories on a XenServer host or a XenServer pool can be created on the iSCSI volumes on the EqualLogic array.
• Multi-Host, Highly Available — This configuration contains XenServer hosts, each with two NICs bonded to provide high availability for iSCSI connectivity, and a PS Series enclosure with redundant RAID controllers. Two of each host's NICs are connected to an Ethernet switch, and the Ethernet switch has connections to all six ports on the RAID controllers. See Figure 5-20 for an illustration of this configuration.
• Fully Redundant — This configuration contains XenServer hosts, each with two NICs (bonded to provide high availability) for iSCSI connectivity and a PS Series enclosure with redundant RAID controllers. One of each host's NICs is connected to Ethernet switch 0, while the second of each host's NICs is connected to Ethernet switch 1. The two Ethernet switches are connected by two Inter Switch Links (ISLs).
Creating a Storage Repository on Dell PS Series Arrays With XenServer 5.0, two types of SRs can be created on PS Series arrays: • LVM Over iSCSI (lvmoiscsi) SRs utilize the Linux Volume Manager (LVM) to create a logical volume per virtual disk image (VDI). The entire volume on the PS Series array is used to hold VDIs. • EqualLogic (equal) SRs utilize the XenServer storage adapter to manage VM storage on PS Series arrays.
Creating an EqualLogic (equal) SR NOTE: To use an EqualLogic SR, the firmware version of the PS Series array must be 4.0.1 or higher. 1 Configure the EqualLogic array, create a group, set a member RAID policy, and create a volume by following the instructions available in the PS Series online help. 2 Enable SSH (secure shell) access for the group members. a In the PS Series group manager user interface, click Group Configuration, and then click the Administration tab.
Moving an SR Between Hosts If you wish to remove an SR from an existing XenServer host and use it with a different host, you must back up the SR from the first host and restore it on the second host: 1 Access the Backup, Update and Restore menu in the local console on the XenServer host or pool master. 2 Trigger an immediate metadata backup to the SR being moved using the Backup Virtual Machine Metadata menu option.
4 Unplug the Physical Block Device (PBD) corresponding to the Storage Repository. Type the following command: # xe pbd-unplug uuid= where is the UUID of PBD noted in step 3. 5 Plug the PBD. Type the following command: # xe pbd-plug uuid= 6 Find the physical volume device SCSI device mapping name on which the SR exists. Identify the volume group (VG) corresponding to the SR.
Configuring Storage
Recovering the Citrix XenServer Host Whenever possible, leave the installed state of Citrix® XenServer® Dell™ Edition servers unaltered. That is, treat XenServer hosts as if they are appliances and do not install any additional packages or start additional services on them. XenServer uses a per-host database to store metadata about virtual machines (VMs) and associated resources such as storage and networking.
4 You are prompted to provide a filename for the backup. Type the desired filename and press . The backup file is written to the selected media. 5 Remove the media with the backed-up file and store it in a safe place. When required you can use this media to recover the XenServer state.
Restoring the XenServer Database After restoring the XenServer host to the factory-default configuration, restore the backed-up XenServer database to regain your VMs and the particular network and storage configuration. This process differs depending on whether you have a single host or a resource pool, and whether the restored XenServer is to be a member or master of the pool. For the default case, you can use the XenServer local console.
Resetting the Root Password If you lose or forget the root password, you can reset it using the XenServer Dell Edition Recovery Media. For more information, see "Using the Recovery Media" on page 64. To reset the root password: 1 Boot using the recovery media. 2 Select your preferred key map. 3 Select Reset the password for an existing installation. 4 Follow the on-screen instructions.
Best Practices High Availability Configuration and IP Storage Traffic Segregation • High Availability — To provide high availability for storage traffic, use Citrix® XenCenter® to create a network interface bond using two NIC ports. • IP Storage Traffic Segregation — To segregate IP storage traffic, create a new host interface. In XenCenter, click on the host and select Management Interfaces.
Scripted Backup of XenServer Host Database It is recommended that you regularly back up the XenServer host database to protect against unintentional configuration loss. This operation can be performed using XenCenter. However, it is beneficial to script a recurring backup from your management system where XenCenter is installed. To accomplish this, perform the following steps from your management system: 1 Create a directory to house the backup batch file and host database backup files. For example, C:\back
3 Create a Scheduled Task. In the Run field, enter the path to the batch file, followed by the hostname or IP address, username, and password. For example: c:\backup\backup.bat 172.17.40.70 root rootpassword Enter the directory you created in step 1 in the “Start in” field.
Shut Down VMs Before a Snapshot In scenarios where application consistency cannot be achieved using frameworks such as Microsoft® VSS or VDS, etc., creating a snapshot or clone of an SR when VMs are powered down ensures a volume that can be cleanly recovered. Scenarios where all virtual disks of a VM are virtualized through the XenServer Domain fall into this category.
3 Take a snapshot of the SR and the Suspend SR (if different than the SR for which the snapshot was created). 4 Power on the VMs on the primary XenServer host. 5 Attach the snapshot of the SR and Suspend SR (if different than the SR for which the snapshot was created) on the secondary XenServer host. 6 Restore the VM metadata to recovery VMs. 7 Boot the VMs on the secondary XenServer host.
Attach the SR Snapshot to the Secondary XenServer Host Make the snapshot volume available to the secondary XenServer host by attaching the SR. For snapshots of iSCSI volumes, just attach the SR to the XenServer host using XenCenter. If the snapshot resides on an Dell PowerVault™ MD3000 RAID enclosure, follow the steps below to attach the snapshot as an SR to a XenServer host. 1 Note the universally unique identifier (UUID) of the SR for which the snapshot was created.
Restore VM Metadata to Recover VMs from a Snapshot 1 Access the Backup, Update and Restore menu in the local console on the XenServer host or pool master. 2 Perform a metadata restoration operation using the Restore Virtual Machine Metadata menu option. The metadata restoration operation can restore only VM records associated with the selected SR, or all of the VM records found potentially from other SRs which were present at the time of the backup.
Adjusting SCSI Timeouts for PowerVault MD3000i Storage Arrays If the XenServer host is connected to PowerVault MD3000i storage arrays, on the XenServer host, change the SCSI timeout value for the SCSI device(s) on the PowerVault MD3000i storage arrays. Create a new udev rule file with name 96-md3000i-sto.rules at /etc/udev/rules.
Appendix Citrix XenServer Dell Edition Local Console Menu Items This section details the available menu options in the local console configuration utility.
