Reading Time: 3 minutesAfter an upgrade to VMware vSphere 5.5 on a Dell PowerEdge R710, I’ve got strange occasion issues, where the hosts got completly disconnected from vCenter (with the ESXi/ESX host’s status as Not Responding or Disconnected in vCenter Server) and there was no way to reconnect, also after restarting the management services. Locking in the ESXi console those kind of errors where notable: Bootbank cannot be found at path ‘/bootbank’. The only temporally solution was power-off the VMs and restart the host. But the issue can randomly came back.

Reading Time: 3 minutesIn previous posts (see ESXi – Partitions layout of system disk and ESXi – More on partitions) I’ve described how are handles the partitions table on the destination installation media of ESXi 5.x (both in the case of a hard disk or a SD/USB disk). With the new ESXi 6.0 the partition tables is similar in the case of a 1 or 2 GB destination device (like a previous SD media), but has some changes in the case of larger devices. Core partitions remain the same with standard size:

Reading Time: 2 minutesVMware EVO:RAIL represent the first Hyper-Converged Infrastructure offerings from VMware, announced in VMworld 2014 and available from the second half of 2014, and based (on the software part) on vSphere 5.5 and VSAN 1.0. Now there is a new software release of VMware EVO:RAIL which includes also support for the VMware EVO:RAIL vSphere Loyalty Program. One of the most notable improvements is that the scale of the hyper-converged infrastructure appliances are now doubled: from beyond the initial four appliances in a cluster and 16 nodes overall to eight appliances in a cluster and 32 nodes […]

Reading Time: 3 minutesDue to the changes in the new vCenter Server 6.0 architecture, the SSO has now been incorporated in the new VMware Platform Services Controller “role”. But the concepts of a global SSO accounts still exist and remain important to manage the infrastructure (and more important during installation and upgrade). If you forget the SSO admin password you can have some trouble. I’ve already wrote on how reset the VMware SSO password in the vSphere 5.1 and 5.5 versions and the procedure remain almost the same also in the 6.0 version.

Reading Time: 2 minutesIn previous post we have already see how add custom drivers to an ESXi installation ISO and how use ImageBuilder to make custom ESXi ISO, but in other cases you may need to define some custom settings during the installation or add custom vib files. Booting from CD is not the only way, but custom ISO could be used also for boot from USB or for boot from virtual devices (like the iDRAC or ILOE). In case you need to build custom ISO with custom option this post could help you: How to Create Bootable ESXi […]

Reading Time: 2 minutesCompatibility remain one of major reason for wait before a major upgrade, but now several backup products are compatible with vSphere 6.0 (see Backup products and vSphere 6.0 compatibility – Updated). Same for several other 3rd part software. But in the backup space there are still some issues that may limiting the choice of running (yet) vSphere 6.0 in production environments. As written in VMware vSphere 6.0 – Upgrade or not upgrade post one was related in CBT in ESXi 6.0 that can impact your environment also if your backup program will already support vSphere […]

Reading Time: 3 minutesAlso some months after the release the new vSphere 6.0, one of the main reason to don’t use in a production environment remain the compatibility aspect. If most of the VMware products it’s fine from this point, it isn’t the same for the 3rd part backup products. One month ago I’ve wrote a post Backup products and vSphere 6.0 compatibility were only few products were available. Now there are some changes in this list.
