Hi,  What type of files are you migrating, is it CIFS or NFS ?  I was not able to find anything with the error messages that are pasted, but came across 2 white paper which may be helpfull  :  NFS FILE MIGRATION TO AN EMC ISILON CLUSTER ( Guidance for optimal data migration of NFS workflows )  SMB FILE MIGRATION TO EMC ISILON (Guidance for optimal data migration of SMB workflows)  let me know if this helps [IMAGE]   Thanks Vanitha
What is the best tool to do data migration from NetApp to Isilon ? Running code 7.0.2.1 and 7.0.2.5 ( Prod and DR)  Facing lot of issues with isi_vol_copy tool while doing file migration from NetApp to Isilon. The volumes on the source array is <3TB in size, <80% utilized and there is enough space for checkpoints.   The isi_vol_copy command works, but files on Isilon have different "create date" time stamps. File properties, create date appear as "Wednesday, ‎December ‎31, ‎1969, ‏‎7:00:00 PM" instead of the acutal create date of files. Resolution: will be fixed in new onefs version.   Incremental copy fails with following error message on code 7.0.2.1. Resolution: The issue Will be fixed in new onefs version. But a fresh new copy job to a different folder on the cluster worked.  inode number: 221847-1-0 flags: REMOVED|KEEP LogMessage {type NDMP_LOG_NORMAL} {msg_id 0} {msg DUMP: Network communication error } {associated_msg 0} {associated_msg_seq 0} LogMessage {type NDMP_LOG_NORMAL} {msg_id 0} {msg DUMP: DUMP IS ABORTED } {associated_msg 0} {associated_msg_seq 0} LogMessage {type NDMP_LOG_NORMAL} {msg_id 0} {msg DUMP: Deleting "/vol/XXXXX/../snapshot_for_backup.227" snapshot. } {associated_msg 0} {associated_msg_seq 0} LogMessage {type NDMP_LOG_NORMAL} {msg_id 0} {msg Connection or IO Error. } {associated_msg 0} {associated_msg_seq 0} nasa: Connection halted: HALT: Connect error!
