#Emcopy migration manual#
On the CLI of the source filer, create a manual snapshot copy by using the following command: Using NetApp Management Console GUI interface, remove the primary member from the dataset. This will mark the snapmirror relationship as external and Protection Manager will no longer manage the relationship.ĥ. Issue the following command to relinquish the primary and secondary member:Ĭ:\> dfpm dataset relinquish destination-qtree-name This prevents Protection Manager’s reaper cleaning up any relationship.Ĥ. Login to the Operations Manager server, and run the following on the command prompt:Ĭ:\> dfm option set dpReaperCleanupMode=Never Sourcefiler> snapmirror update sourcefiler:/vol/newsourcevol/qtreeģ. Before doing this, make sure that nobody is accessing the data by removing the share.
On the day of the cutover, perform a final snapmirror update on the new volume. This took some time, and I also updated nf so that snapmirror updates daily.Ģ. Sourcefiler> snapmirror initialize -S sourcefiler:/vol/oldsourcevol/qtree sourcefiler:/vol/newsourcevol/qtree On the CLI of the original source filer, copy the original qtree to a new qtree on a new volume by using the following command: Generally, the steps below are the combination of the snapmirror CLI commands and Protection Manager configuration tasks.ġ. I consolidated this information and generated the steps below. I did not find a straight forward solution, but I found bits and pieces of information.
#Emcopy migration how to#
Like any sane IT professional, I googled how to do this. How do I move the qtree snapmirror sources without re-baselining the snapmirror relationship using Protection Manager? Unfortunately, there is no way to do this using Protection Manager, and re-baselining is not an option – it has terabytes of data that may take couple of weeks to complete. The problem is, this volume contained qtrees that are snapmirrored to our Disaster Recovery (DR) site and it is being managed by NetApp Protection Manager. I have to move it to a different volume contained in an aggregate with plenty of space on the same filer. I cannot expand the volume since its aggregate is also low in space. Moving a Qtree Snapmirror Source in NetApp Protection ManagerĪ couple of weeks ago, one of the volumes in our NetApp Filer storage almost ran out of space. This entry was posted in Data Storage, Technical How-to on Novemby admin. To migrate UNIX/Linux files, use the UNIX rsync utility to copy files between source and target VNX. Check the new CIFS shares and make sure the users are able to read/write on the share. Update the DNS record too if necessary.Ĩ. This procedure entails unjoining the source and target CIFS server from Active Directory (AD), renaming NetBIOS name on the new CIFS server, joining back the CIFS server, etc. Follow EMC156835 to rename the CIFS server so that the new CIFS server will have the name of its old CIFS server. Disconnect users from the source CIFS server and make the file system read-only.Ĭ. You may also spot check the ACLs and/or run tools to compare files and directories between the source and target.Ī. Analyze emcopy log to make sure files are being copied successfully. This will temendously cut the time needed to update the files on the final day of migration.Ħ. Create an emcopy script to sync the files every night.
Run emcopy.exe to perform baseline copy.ĥ. Use lgdup.exe utility to copy local groups from the source CIFS server to the target CIFS server.Ĥ. You can also use the sharedup.exe utility.ģ. Copy the share permissions (or ACL) and the NTFS root folder ACLs from the old share to new share. Create the necessary VDM (Virtual Data Mover), File System, and CIFS server on the target VNX machine.Ģ. In general, I used the following procedure:ġ. There are several steps you need to follow for a successful migration.
#Emcopy migration free#
EMC provides these free tools including emcopy, lgdup, and sharedup to accomplish the migration task.
#Emcopy migration windows#
One method I used recently to migrate Windows files (CIFS) was to copy files between the source CIFS server to the target VNX server using the emcopy migration suite of tools from EMC. There are several methodologies in migrating files to EMC VNX.
