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.
You could specify the password in the command by doing, but you always have to trail the username with a colon.
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. 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.
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.
