Snapdrive 7.1.5P2 and vSphere 6.7 U2

amayacitta

Hey all,

 

IMT doesnt specifically list support or lack of support for this, however we are having issues with Snap Drive 7.1.5 connecting to vSphere 6.7 U2 to map RDM LUN's. We can connect to 6.5 no problem, however 6.7 whether the VC or the ESXi host can't connect, the general error is below. This has been tried against multiple 6.7 instances and from multiple snap drive installations, so it's not specific to a particular version of windows, tried many of them, they all produce the same error.

 

If I enable schannel debugging I can see TLS 1.2 connects fine.

 

An SSL server handshake completed successfully. The negotiated cryptographic parameters are as follows.

Protocol: TLS 1.2
CipherSuite: 0xC028
Exchange strength: 256

 

Here is the error.

Has anyone else seen this? I can connect to the VC and ESXi fine using IE on the same/different machines.

My colleague Wayne found a fix, seems even though the OS and IE can connect using TLS 1.2 - snap drive doesn't so! if you enable older versions of TLS then snap drive connects. To mess with the versions available on VC 6.7 follow this article.

So which TLS settings exactly did you disable/enable to solve the problem? Has TLS 1.0 to be enabled?

amayacitta

It's been a while now but pretty sure we just left TLS 1.2 enabled.

 

If your running Linux the commands are:

 

cd /usr/lib/vmware-TlsReconfigurator/VcTlsReconfigurator
./reconfigureVc update -p TLSv1.2

If you running windows the commands are:

 

cd %VMWARE_CIS_HOME%\TlsReconfigurator\VcTlsReconfigurator
reconfigureVc update -p TLSv1.2

Hi

 

I have the same issue ... we found that work around but my question is .... is it supported by Netapp ... in the Compatibility matrix .. it says NO !!!!!!

I'm getting a permission denied when I try to run the commands from the shell.  What am I missing?

 

PermissionError: [Errno 13] Permission denied: '/var/log/vmware/vSphere-TlsReconfigurator'

Are you getting that error entering the folder? Remember the script is inside the folder. Also make sure you login as root.

 

Follow the below KB:

is that configuration supported by NetApp ??????
