Yes!  You can migrate from multiple NetApp filers simultaneously.  If you had 5 NetApp filers, you can run 5 isi_vol_copy, 1 against each filer at the same time.  You wouldn't ant to run all five on a single node, but spread out the isi_vol_copy runs on different nodes.  So if you have a 5 node cluster, you could run 1 on each node.  You can move a lot of data very quickly this way.

Hi Andrew,

Thanks for your feedback. I have tested the isi_vol_copy and its working fine using ndmp protocol. However I would like to check with you if there is any requirements in order to get isi_vol_copy to work with NetApp. My situation is like this

1) I have 4 Filers to copy from

2) I have started the isi_vol_copy for one filer and its running now

3) I wanted to start another session of isi_vol_copy for another filer but failed. I get a "permission not permitted "  errror after keying the password. Please take note that the password is the same as the previous filer.

4) Yes, I have also tried to login to the filer with the password given using Putty and it works.

5) Could it be that, for this filer, they have anoher password for ndmp based backup/migration.

Please do advise if I need to perform any preconfiguration on the filer before starting the isi_vol_copy session.

Vimal,

You should consider creating a separate account (however, to answer your question yes root has the necessary permissions and you demonstrate that with 1 of 6 filers; in fact, root is the default account if you don't specify a user with isi_vol_copy) as follows on the NetApp:

ndmpd status

ndmpd on (if necessary)

useradmin user add <insert_user_name> -g "Backup Operators"

ndmpd password <insert_user_name>

The last command will return a 16 char string (it is the 128-bit MD5 hash) which you would then use with the isi_vol_copy command.

Here is a KB article also which provides some of the information above.

Error sending text authentication" when running the isi_vol_copy command

Hi Chris,

Thanks for the steps provided. I guess this were the similar steps need by CTA to perform NDMp based backup. Anyway, once I have obtained the 16 char string (it is the 128-bit MD5 hash), how do I key it in. The reason I ask this is because, if we use the below command, the user will be root by default

isi_vol_copy 10.10.10.10:/vol/test /ifs/data/test -full

Should I use,

isi_vol_copy 10.10.10.10:/vol/test /ifs/data/test -full -sa ndmpuser:16 char string

I will give this shot tomorrow and give the team updates.

Hi Guys,

For some weired reason this command did not work

isi_vol_copy netappfiler01:/vol/cifs1   /ifs/data/cifs1  -full

Password:xxxxxxxxxxx

but, if i were to perform it in this manner it works

isi_vol_copy netappfiler01:/vol/cifs1   /ifs/icifs1  -full -sa root:xxxxxxxxxxx
