Erreur VMware_VCMSDS
Posted by Damien in VMware, vSphere 4.X on December 8, 2011
Il arrive d’avoir l’erreur suivante toutes les minutes dans les logs de votre vCenter :
Active Directory Web Services encountered an error while reading the settings for the specified Active Directory Lightweight Directory Services instance. Active Directory Web Services will retry this operation periodically. In the mean time, this instance will be ignored. Instance name: ADAM_VMwareVCMSDS
Pour supprimer ce message d’erreur, modifier la clé de registre suivante sur le serveur vCenter :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ADAM_VMwareVCMSDS\Parameters
Supprimer la clé “Port SSL”, puis recréer une clé DWORD “Port SSL” avec une valeur décimale de 636.
Redémarrer ensuite les serveurs VMware_VCMSDS et AD Web Services du serveur vCenter.
Mise à jour d’un carte HBA Emulex sur un serveur vSphere ESX.4x
Posted by Damien in Hardware, VMware, vSphere 4.X on November 21, 2011
Voici la procédure pour la mise à jour du firmware d’un carte HBA Emulex sur un serveur vSphere 4.x
Tout d’abord, il faut installer sur le serveur esx, l’application HBAnywhere que l’on peut télécharger sur le site d’Emulex, ici
Installer le paquet avec la commande suivante :
rpm -Uvh elxocmcore-esxNN-<kit version>.<arch>.rpm
Copier les sources du firmware à un emplacement du serveur ( ex: /home/admin/***.all)
Ensuite, lancer la commande suivante pour connaitre les cartes HBAs se trouvant sur le serveur :
hbacmd ListHBAs
Lancer la commande suivante pour mettre à jour le firmware de la carte :
hbacmd download “WWW de la carte” /home/admin/***.all
Voila.
Activer / Désactiver l’option VAAI sur Vmware vSphere 4.x
Posted by Damien in Stockage, VMware, vSphere 4.X on November 21, 2011
Il est parfois nécessaire de devoir désactiver l’option VAAI pour des soucis de support avec la baie de stockage utilisée dans dans l’infra.
Allez dans dans l’onglet “configuration” de l’esx, puis “parametres avancés”. Passer à 0 les paramètres suivant pour désactiver le VAAI ou à 1 pour l’activer :
Dans “DataMover”.
- DataMover.HardwareAcceleratedMove setting to 0
- DataMover.HardwareAcceleratedInit setting to 0.
Dans VMFS3.
- HardwareAcceleratedLocking setting to 0.

Les nouveautés de XenServer 6.0
Posted by admin in Citrix, Xen Server on November 18, 2011
Xen Server est sorti le 4 Novembre. Voici les nouveautés de cette version. Je n’ai pas encore eu le temps de tester cette version. Pour plus d’information ( Citrix )
Integrated Site Recovery (Disaster Recovery). Remote data replication between storage arrays with fast recovery and failback capabilities. Integrated Site Recovery replaces StorageLink Gateway Site Recovery used in previous versions, removes the Windows VM requirement, and works with any iSCSI or Hardware HBA storage repository.
Integrated StorageLink. Access to use existing storage array-based features such as data replication, de-duplication, snapshot and cloning. Replaces the StorageLink Gateway technology used in previous editions and removes requirement to run a Windows VM with the StorageLink components.
GPU Pass-Through. Enables a physical GPU to be assigned to a VM providing high-end graphics. Allows applications to leverage GPU instructions in XenDesktop VDI deployments with HDX 3D Pro.
Virtual Appliance Support (vApp). Ability to create multi-VM and boot sequenced virtual appliances (vApps) that integrate with Integrated Site Recovery and High Availability. vApps can be easily imported and exported using the Open Virtualization Format (OVF) standard.
Rolling Pool Upgrade Wizard. Simplify upgrades (automated or semi-automated) to XenServer 6.0 with a wizard that performs pre-checks with a step-by-step process that blocks unsupported upgrades.
Microsoft SCVMM & SCOM Support. Manage XenServer hosts and VMs with System Center Virtual Machine Manager (SCVMM) 2012. System Center Operations Manager (SCOM) 2012 will also be able to manage and monitor XenServer hosts and VMs. System Center integration is available with a special supplemental pack from Citrix. For more information refer to the Microsoft System Center 2012 Virtual Machine Manager page.
Distributed Virtual Switch Improvements. New fail safe mode allows Cross-Server Private Networks, ACLs, QoS, RSPAN and NetFlow settings to continue to be applied to a running VM in the event of vSwitch Controller failure.
Increased Performance and Scale. Supported limits have been increased to 1 TB memory for XenServer hosts, and up to16 virtual processors and 128 GB virtual memory for VMs. Improved XenServer Tools with smaller footprint.
Networking Improvements. Open vSwitch is now the default networking stack in XenServer 6.0 and now provides formal support for Active-Backup NIC bonding.
VM Import & Export Improvements. Full support for VM disk and OVF appliance imports directly from XenCenter with the ability to change VM parameters (virtual processor, virtual memory, virtual interfaces, and target storage repository) with the Import wizard. Full OVF import support for XenServer, XenConvert and VMware.
SR-IOV Improvements. Improved scalability and certification with the SR-IOV Test Kit. Experimental SR-IOV with XenMotion support with Solarflare SR-IOV adapters.
Simplified Installer. Host installations only require a single ISO.
Enhanced Guest OS Support. Support for Ubuntu 10.04 (32/64-bit). Updated support for Debian Squeeze 6.0 64-bit, Oracle Enterprise Linux 6.0 (32/64-bit) and SLES 10 SP4 (32/64-bit). Experimental VM templates for CentOS 6.0 (32/64-bit), Ubuntu 10.10 (32/64-bit) and Solaris 10.
Workload Balancing Improvements. New, ready-to-use Linux-based virtual appliance with a smaller footprint replaces the Windows-based virtual appliance and eliminates the Windows licensing dependency.
XenDesktop Enhancements. HDX enhancements for optimized user experience with virtual desktops, GPU Pass-Through, and increased VM and XenServer host limits.
VM Protection & Recovery. Now available for Advanced, Enterprise and Platinum Edition customers.
NFS Support for High Availability. HA Heartbeat disk can now reside on a NFS storage repository.
XenCenter Improvements. XenCenter operations now run in parallel, and XenCenter will be available in Japanese and Simplified Chinese (ETA Q4 2011).
Host Architectural Improvements. XenServer 6.0 now runs on the Xen 4.1 hypervisor, provides GPT support and a smaller, more scalable Dom0.
