Today I want to try provisioning and configuring Amazon AWS instances with Chef. To do that I have:
More and more people reconfigured their sites to ssl connection. So I decided to use ssl certificate and secure connection on my blogs too.
The Chinese CA WoSign offers free SSL certificates which are valid for 2 years and may contain up to 100 domains each (multi-domain/SAN/UCC) which is very useful to host various domains on one single IP address (Better option than SNI if you still have Windows XP clients). Before you stop reading because you don't trust a Chinese company for your website encryption please keep in mind that you don't have to trust them at all! You generate the SSL key on your server and only send them the CSR (certificate signing request) which doesn't contain any private information.

Today I tried to upgrade my standalone (not in Cluster) host (HP DL 180 G6) with esxi 6.0 and Update Manager. But when the process starts I had received this error:

Few weeks ago VMWare released VSAN Health Check Plugin. This plugin allows monitoring and troubleshooting your VSAN 6.0 Clusters. There are two versions of this plugin: first for Windows based vCenter Server and the second – for Linux VCSA (rpm file). VSAN Health Check plugin allows you to collect information about Cluster and its health, which would otherwise needed to be gathered via RVC or CLI. There is also a vib file which you need to deploy on your esxi hosts in VSAN Cluster. The deployment of the VIB file can be done through vSphere web client (other methods are through RVC, VUM or manually via CLI with “esxcli software vib” commands).
