Hello,  What is the error you are getting?   When you do the test credentials does it display an error?  If you can ping the VSM appliance from the array, and you get an error testing credentials the most common problem is legacy-crypto-protocols have been disabled. GrpName>grpparams crypto-legacy-protocols enable See if that resolves it. Make sure you VSM is on the Array Management network if you are using Dedicated Mgmt port.  It won't connect to the iSCSI only network. On general purpose you should upgrade to 10.0.2. which is the most current version.  Not related to this issue. If that does not work I would suggest you open a support case so they can review the logs.   Regards, Don    
I just installed a new VSM 5.0.0 appliance in my vSphere 6.5U2 environment.   I have an EqualLogic group with members on v10.0.1 of the EQL software, which I think should work.   I've triple-checked the IP addresses.  I can connect to the EQL group via the java client with the username and password I'm using in the VSM config. Any suggestions for where to look to for debug messages or for what to do differently? Thanks.
VSM 5.0.0 new install can't connect to EQL group
