Reading Time: < 1 minute One year ago, I’ve described how to disable the certificate warning in the Windows View Client 5.0, by using GPO or a direct change in the local registry (on the client). Now, with the new version 5.1 of the View Client there is a new way client side:
Reading Time: < 1 minute I’ve got a case of a host upgraded to VMware vSphere 5.1 with a determinist PSOD during each host reboot or shutdown (I’ve found the issue during the first patch update). No difference if hosts where rebuild from scratch with a similar configuration. And no difference with all recent ESXi patches. After a full upgrade of each BIOS, firmware and drivers (and of course the HCL verification) I’ve only found the KB 2038281 (ESXi 5.1 host fails with a purple diagnostic screen when Beacon probing is enabled). Syntoms where similar: Cannot reboot a ESXi 5.1 […]
Reading Time: 2 minutes The available VCDX defense dates (and locations) are been recently announced on a thread in the VMware Community. Some were already well know (during the PEX event). The interesting aspect is that is still possible reach the VCDX4(-DV) certification for the entire 2013 (big change on what was announced one year ago and really a good opportunity for VCDX candidates): Candidates at all 2013 VCDX Defenses will be offered the opportunity to submit and defend vSphere4 and vSphere5-based designs in pursuit of the VCDX4 credential. Candidates may also choose to submit and defend vSphere5-based designs […]
Reading Time: 5 minutes There are different reason where you can you loose or corrupt your partition table of your VMFS volumes: resignature from another system (for example the backup server, if connected in SAN mode), a human mistake (datastore / delete), or maybe some storage issues. In this case usually the VMFS partition is still there and also the related data: you have “only” to rebuild the right partition table. But this could really simple if you follow the recommended practice to have only one VMFS partition on each disk. In this case you have only to build […]
Reading Time: 2 minutes As written in the previous post, one common issue with recent servers of new generations is that maybe the NIC drivers are not included in the standard ESXi ISO. An if you use the vendor (or a personal) customized ISO, could be possible that during a patch update or a version upgrade you loose the drivers and the system is no working anymore. In those cases you may have an ESXi that complete his bootstrap, but without any network connectivity is not usable and could be hard to fix the missing drivers because VUM and […]
Reading Time: < 1 minute If you have a new NIC card or a server of a new generation could be possible that the right driver is missing in the standard ESXi installation ISO. And without a working networking is not possible install the ESXi (the installation will stop because one requirement is at least a supported NIC). Maybe the hardware vendor has a customized version of the ISO, but IMHO I don’t like this option (in some cases it could give some issues).
Reading Time: < 1 minute There could some cases where you may have some Windows (Server) completely isolated from the Internet, for example in some appliances or storage solution. One interesting aspect that learn on Windows products during a DataCore training was that in this case you can have some delay in the user interface, both on the DataCore GUI, but also on the Windows one.
