Did you know you can update your hardware with VMware Update Manager? Each vendor has a depot URL that ties into VUM.
In VUM, navigate to Configuration – download settings – add download source, enter the URL. Here is a list of vendors I have gathered so far:
IBM: Unfortunately they do not have a direct URL to tie in with UM. Updates are obtained by searching “fix central” on the IBM website.
Cisco: I have not found one yet. Since everything is updated in UCS, this VIB directory may not exist.
I will attach a script later to include all or one.
