Emcopy migration software#
I cannot use a product like DoubleTake as the destination is an EMC VNXe, which I don't have access to, so I am unable to load any software on the destination. I am looking for a suggestion on doing this final file move to ensure that the destination contains all current files. I have tried some other applications with similar results. The later may work, though it doesn't give me good assurance that the destination files are up-to-date.
If you don't include same files it ignores them leaving them on the source. I have tried RoboCopy: If you include same files, it copies the file again before deleting the source. In addition if the file is now an orphan on the destination, it needs to be removed as well. I have not been able to find a product which acts in this way. Since the file source is so slow I don't want to move files which are the same on the source and destination, I only want to delete the source. The way I want to do this is by a final move of files. Due to the time it took to copy the data much of the copied data is now stale and needs to be updated. Because of this it took six weeks to copy the data to the new source. The legacy data is stored in file vault application which retrieves files very slowly. Hope this helps you.I am migrating six terabytes of data from legacy systems to new. I spent several hours figuring this out on my own. Also, you’ll want to disable any data migrations on the source VNX prior to the copy, so that you don’t run into contention for performance resources. Pretty sure the data copy will work with NFS as well, you’ll just need to create your NFS exports. You’ll have to use Sharedupe for that or recreate them by hand. It will copy as fast as possible.Ī couple other things to note. The major drawback from using this migration method, is that you have no control over speed. If you have all your stuff in order, you’ll see “msg SnapSure file system creation succeeds” which means the NDMP session created a checkpoint successfully and is starting to copy data from that checkpoint.
Emcopy migration password#
You could specify the password in the command by doing, but you always have to trail the username with a colon.
Emcopy migration full#
This command will run a full copy using the ndmpuser1 account and will as for a password, so you don’t have to show it in plain text. Isi_vol_copy_vnx 10.10.10.10:/root_vdm_1/FILESYSTEM1 /ifs/data/FILESYSTEM1 -sa ndmpuser1: -full The nice thing about this migration command is that if the destination folder doesn’t exist on the Isilon, it will create it with the exact same ntfs permission as the source. More than likely it’ll be in the /ifs/data folder, which you’ll want to probably specify your VNX filesystem name as the root folder, like this: /ifs/data/FILESYSTEM1 Next you’ll have to figure out where to put your data at on the Isilon. Your path will then be /root_vdm_1/FILESYSTEM1 which you’ll use for the source path in the isi_vol_copy_vnx command. If you’re using a VDM, you’ll probably notice your path beginning with: Your output will probably be a bit much, but you’ll need to look towards the top, find server_2 and look at the paths for each of your filesystems. This is important because if you’re using a VDM, it changes the root path of your filesystem. Next we’ll have to find the absolute path of your filesystems and shares.
You’ll run through the prompts, you can select the defaults, but put in password you’ll remember…write that down. nas/sbin/server_user -add -ndmp_md5 -passwd To do so, we’ll need to login to the control station and run the following command: You can use the default NDMP user account built into the VNX, or you may want to create a new one, so that you don’t screw with any existing backups you may be using that account for. But before we can get rolling we need to make sure we have some information and our NDMP user setup.
Migration or Tech-refresh A term used to describe the process of changing an existing production storage system with another storage system. Since we’re migrating from a VNX, of course, EMC has a special command tailored for the VNX, so we’ll be using the command isi_vol_copy_vnx. some migration solutions, a disruption period is necessary in order to begin hosting resources from the destination system.
Emcopy migration how to#
In my example, I’ll be showing you how to migrate data from a VNX. I believe if the source NAS supports NDMP, you should be good to go. I know EMC supports running copies from VNX and Netapp, but outside of that, you may be on your own. This tool uses NDMP to transfer the data from the source NAS to the Isilon. In the past I’ve always used EMCopy or Robocopy, but as I was looking through some EMC docs, I came across this Isilon-only method called isi_vol_copy, which also happens to be the command. So I don’t have much Isilon experience as I’m a block storage guy, but recently I was asked to help out a customer with a file migration, so I started looking into it.
