Migrating with isi_vol_copy

Question

I am working on getting an inital copy from a netapp filer to a new isilon running and am having authentication errors when running the command. This is the first time using this command. # isi_vol_copy :/vol/ /ifs/testcopy/ -sa : -full Password: Error sending text authentication: Error: Connection has not been authorized # I'm using the root user of our netapp in the -sa. I've pre-created the destination directory on the isilon. The isilon and the netapp are on the same subnet so I do not suspect any network issues. I've gone through what documentation i have for the isi_vol_copy command, but everything looks correct. Am I missing some configuration I need to do on the netapp or the isilon? Thanks in advance.

Hi,

I use isi_vol_copy intense.

You may verify netapp options setting:

ndmpd.access	all
ndmpd.authtype	challenge
ndmpd.connectlog.enabled	off
ndmpd.data_port_range	all
ndmpd.enable	on

ndmpd.ignore_ctime.enabled off

ndmpd.offset_map.enable	on
ndmpd.password_length	16
ndmpd.preferred_interface	disable	(value might be overwritten in takeover)
ndmpd.tcpnodelay.enable	off

Or look at netapp ec/message or etc/log/backup file.

Regards,

Ralf

My ndmpd options are all the same as you are listing they should be. the 'isi_vol_copy intense'? is that a different tool? Man isi_vol_copy doesn't list intense as an option or switch for the command.

enable rsh access to the Netapp for the Isilon node you are running the copy from?

Are you using root from the NetApp array and not the ndmpd user credentials? To find the ndmpd creds for the userID SYSTEM type this and use these creds in your isi_vol_copy command, Although this thread is from April and i'm sure you've completed this migration
