ISCSI Datastore cannot mount back

I have the following issue.
Once Synology LUN was mounted to ESXi as a datastore and used.

Somehow connection lost and now can not mount back to ESXi. If I try it shows empty:

I tried the following command: esxcfg-volume -l

It's empty..

Any idea how can I get back almost 1TB of my data?

Probabaly want to call VMware support, looks like the datastore was deleted.

Be very very careful when using iSCSI-LUNs from Windows.
I have seen to many cases when trying to do so made the case worse.
Do you have dd on that Windows machine ? - then try to create a dump of the first 1536MBs.
At the moment there are no free ware tools for Linux or Windows that can reliably mount the latest VMFS version.
vmfs-tools for Linux when installed from standard repositories can not read vmdks larger than 256GB.
Anyway - please read
http://vm-sickbay.com/create-a-vmfs-header-dump-using-an-esxi-host-in-production
and provide a download for the compressed dump.
With the dump I can suggest what to do next.
