“Download failed” when using proxy for VCSA update

There is still a bug in current VCSA 6.5 U1g. When you use a proxy server in management interface (Port 5480) to access VMware repository for updates, you get a “Download failed” error. The problem is that in configuration file https-proxy setting will not be set. To resolve the issue, do the following:

  1. Log in to VCSA shell
  2. Edit /etc/sysconfig/proxy
      • set entry HTTPS_PROXY like HTTP_PROXY
      • example:
        • HTTP_PROXY="http://proxy:3128/"
        • HTTPS_PROXY="http://proxy:3128/"

     

No reboot or service restart is necessary. Just re-try to scan repository.

Warning in VCSA Upgrade Wizard

A short (and funny) one. At my last upgrade of VCSA from 6.0 to 6.5 I got a warning that says: “User vdcs does not have the expected uid 1006”. Furthermore warning is talking about a KB article to read but without any hint what article it is talking about. This message has something with the vCenter feature Content Library. According to VMware Support when Content Library is not used, you can continue with upgrading VCSA – and using Content Library after the upgrade. When feature is use, call VMware Support.

How to find information to create device specific PSP rule

When you connect your storage device to your ESXi hosts, a Path Selection Policy (PSP) will selected based on defined rule set.
