We have performed all the hostchecker checks on target machine and all the tests are success, and still we are receiving error while creating a VDB.
Yes it's Linux system ( the target machine is a exadata x2-2 machine, and we have verified all the hostchecker checks for target was successful.
here is the check which shows the mount/umount privileges to delphios user
/home/delphios$ sudo -l

Runas and Command-specific defaults for delphios:

I am able to mount the filesystem from remote server to target, but it is not working with delphix engine... seems some configuration issue at delphix engine, need to mount/or give the permission to the target machine-- or target ip should be added in somewhere in t delphix engine side.
Are you able to mount the the "public" share on the Delphix engine? Delphix has a very small shared directory for testing purposes:
$ mkdir /tmp/test
$ sudo mount -F nfs -o rw,fg,hard,rsize=1048576,wsize=1048576,vers=3,nointr,timeo=600,proto=tcp,sec=sys nstack-4210.acme.com:/public /tmp/test
$ sudo umount /tmp/test
Does the host have multiple IP addresses? If the mount request comes from a different IP than the one that was specified when the environment was added, Delphix will reject it. Delphix blocks attempts to mount the shares from IP addresses other than the one that was specified in the environment.
There is a configuration parameter that Delphix technical support can change to turn off this layer of security if needed.
This is an exadata (X2-2 half rack) engineered system, and it is having multiple ip addresses. We are trying to create VDB's on multiple hosts it is failing on all the nodes.
How to know what ip address was added to the Delphix engine when it configured.
and How to change the configuration parameter settings to allow shares to mount?
When you add a host name or IP address as described here:
Only Delphix Technical Support can change the setting. Please log a new technical support case and upload a support bundle as described here:
