can't delete filesystem, Error 2250

this is the stuff on the volume, converted it to uxfs, mounted it and had a look, some iscsi stuff that was replicated some time ago:

root@winzfs006 iSCSI]# ls -lRt
.:
total 16
drwxr-xr-x 2 root bin 1024 Nov 8 2007 fs77_T3_LUN10_CK200011111111_0000
drwxr-xr-x 2 root root 8192 Nov 8 2007 lost+found

Is there a way to import this iscsi lun into our iscsi server to delete the iscsi lun that way.

I'll prefer to engage NAS support at this point. They can analyze and found more specific details and guide you accordingly.

However, there may be suggestions/comments from others experts in this forum.

Thanks,

some guy from EMC had a look, he didn't tell us what he did but looks like he modified
