Reading Time: 2 minutes In the previous post we have described how the command line of a Dell PowerVault storage allows several more operations compare the graphical interface. For example, the disk initialization is just one of the several troubleshooting cases where it becomes mandatory to rely on the command line (or on technical support). Another case is where the RAID of a disks group go into the “corrupted” state: at that point, again, there is no simple solution because you have limited options in the graphical interface. Again, the solution is switch to the command line and use the […]

Reading Time: 3 minutes One of the advantages of Dell PowerVault storage, with the MDxxx series, is that they use disks with identical bays of the server version (obviously depending on the generation, there will bays like the G9 servers or  bays with the same G10, G11, G12 servers form factor). In addition, disks are theoretically interchangeable because are the same models (almost from Seagate vendor, ad least for spinning disks). However, in practice, this was true with MD30xx models and derivatives, but with the recent series (MD32xx or MD36xx), there are some limitation based on the firmware version […]

Reading Time: 5 minutes The upgrade path from Veeam Backup & Replication 6.x to the new version 7 is almost simple and fast: basically you have to upgrade first the Backup Enterprise Manager and then the Backup & Replication part, and finally apply the patch to bring it at the Backup & Replication 7.0 R2 release. The entire upgrade procedure is almost fast and usually can take around 30 min for a simple install with only one single system. Of course before doing the upgrade you need to verify the license file (you need a new one for version […]

Reading Time: 5 minutes As written in a previous post, with the introduction of vSphere 5.0 in addition to the installable version of vCenter Server (which still requires a Windows operating system), there is also a Virtual Appliance version (called VMware vCenter Server Virtual Appliance). VMware vCenter Server Virtual Appliance (vCSA) is a VMware’s official VA that can be used as an alternative way to implement a full vCenter Server, instead to install on a Windows Server (that must be deployed first). Unlike the installable version, it does not require a Windows Server license and instance, but is rather […]

Reading Time: < 1 minute VMware has recently released a new new exam to qualify candidates for the VMware Certified Professional 5 – Data Center Virtualization (VCP5-DCV) Certification. This new exam (exam code VCP550) is based on vSphere v5.5, where the existing exam (exam code VCP510) is based on vSphere 5.0/5.1. Passing either of these exams will earn VCP5-DCV certification. Note that does not change the course requirement (for more information see the official certification page) and that now also for VCP exam you need to request an authorization. Is a change in the common approach of have certification based only on […]

Reading Time: 3 minutes After updating the vCenter Server part to version 5.5, you can focus on the host part. The update of the ESXi host can be completed, as usual, in several ways: Manual update with the installation CD of ESXi (by selecting upgrade and keep VMFS datastore) Manual update using the CLI Automatic updating via vSphere Update Manager (VUM) There are other ways, all discussed in the VMware KB 2058352 (Methods for upgrading to ESXi 5.5).

Reading Time: 5 minutes The VMware vCenter upgrade has some possible issue, considering also that the SSO part is changed from the one implemented in vSphere 5.1. VMware has released the vSphere 5.5b (specifically for the vCenter Server application, both installable and vCSA editions) just before the Christmas holiday. Mostly another bunch of fixes around vCenter Single Sign-On functionality and upgrade errors, so be sure to use this one for the upgrade to reduce the possible issues. Note that most of the issues are related to the vCenter components:
