I faced a strange problem when trying to copy (upload) any file (ISO, vmdk, OVA/OVF, etc.) to the VMFS Datastore in VMware vSphere (6.7). When I click on the “Upload Files” button in vSphere Client interface, the error “The operation failed” appears.

In VMware vSphere 5.0, datastores have their own set of access control privileges. As a result, you might need to reconfigure your permissions to grant the new datastore privileges. This is required if you have nonpropagating Read-only permission set on the datacenter for users. Unable to access the virtual machine configuration: Unable to access file File Server File Server.vmx. Virtual disk 'Hard disk 1' is not accessible on the host: Unable to access file File Server File Server.vmdk. Virtual disk 'Hard disk 2' is not accessible on the host: Unable to access file File Server File Server1.vmdk.

There is the following message in the error window:

Hoi4 the new order. Typically this problem occurs due to certificates that the browser does not trust. If you are using self-signed or custom certificates, open the URL below in a new browser tab and accept the certificate, then retry the operation.

As you can see from the error, the problem related to the untrusted SSL certificate used on the vCenter server (the certificate is self-signed or issued by an untrusted certificate authority). To solve this problem, you need follow the instructions from in article “SSL Certificate security warning on vSphere”.

To add a vCenter certificate to the list of trusted certificates, go to vSphere start page and click “Download trusted root CA certificates” in the bottom right corner.

In Downloads go to the .certswin folder (there are separate folders for Windows, Linux and Mac certificates). Double-click the *.crt file and click the Install Certificate button.

Use the Certificate Import Wizard to place your vCenter certificate to the trusted root certificate store on your computer (Local Machine -> Trusted Root Certification Authorities).

Open vCenter web interface and make sure that the untrusted certificate warning doesn’t appear. Now you can upload files to your VMFS datastore.

In Firefox, you need to add the vSphere certificate to trusted (exception) list in your browser settings or switch Firefox to use certificates from the Windows certificate store: about: config -> security.enterprise_roots.enabled = True (otherwise you will see an error “Secure Connection Failed”).

FireFox, unlike other browsers (Chrome, Opera, IE) by default uses its own trusted certificate list.

Indramat tdm manual. Rexroth ManualsOctober 22, 2018Ah, technical manuals. And with the service life of many Indramat products measured in decades (quite literally; there are Indramat systems installed in the 1970’s that are only now coming up for refurbishment), locating that manual from 30 or 40 years ago can be a real challenge!Fortunately, when you need manuals for your Rexroth products, you can, and spare yourself the horrors of searching through that old storage room in the sub-basement. How many of us actually keep technical documentation organized as well as we should? This firm’s unofficial motto was “RTFM – Read The Fantastic Manual.” The phone support staff had standing orders to ask every customer if they had their manual handy, and if the answer was no, to politely request that the customer locate their manual and then call back.We don’t do this.We realize that having the manual (or having had it at one time) and being able to find the manual can be two very different things. It’s hard to imagine a less thrilling topic, but when you need them, you really need them.I remember one company we worked with.
