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.

Have you checked that the Delphix user in your target machine has the right sudo permissions to mount and unmount (I assume it's a Linux host)?

Hi,
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
Matching Defaults entries for delphios on this host:
requiretty, env_reset, env_keep="COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE LC_COLLATE LC_IDENTIFICATION
LC_MEASUREMENT LC_MESSAGES LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY", !requiretty
Runas and Command-specific defaults for delphios:
User delphios may run the following commands on this host:
(root) NOPASSWD: /bin/mount, (root) /bin/umount, (root) /bin/mkdir, (root) /bin/rmdir, (root) /bin/ps, (root) /bin/pargs

Hi,
I am able to create the directory with the delphios user in the mount point,
/u01/delphix_mount$ mkdir testvdb

Hi,
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.
regards
Prem

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.
Thanks,
Neal

Hi,
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?
Regards

When you add a host name or IP address as described here:
https://docs.delphix.com/display/DOCS42/Adding+an+Oracle+Single+Instance+or+RAC+Environment
Only Delphix Technical Support can change the setting. Please log a new technical support case and upload a support bundle as described here:
https://support.delphix.com/hc/en-us/articles/201655216-Best-Practice-Uploading-Support-Logs
Thanks,
Neal
