NDMPCOPY Query

[oneshotshearer]

Hello,

I was asked to perform an NDMPCOPY of data.  This was from one controller to another.

I kicked off the following task from a unix client using SSH commands (so it wont lock up the controller)

ssh sccnas02 ndmpcopy -da root:xxxxxxxx /vol/thistle_a/topdir/data 172.31.241.4:/vol/scctmp01/topdir/Thistle_A/Data

I wasnt sure if this was successful or not as when I checked the log:

sccnas02> rdfile /etc/log/ndmpcopy.20110517

"May 17 15:11:37 GMT [ndmpc:4]: Starting ndmpcopy operation
May 17 15:11:37 GMT [ndmpc:4]: Auto negotiated to version 4

May 17 22:57:59 GMT [ndmpc:4]: Ndmpcopy done"

Is there another method/ place where I can confirm if this was a successful copy - unfortunately there was other data being copied into the "scctmp01" volume so not as easy as comparing the size of volumes.

Any help on this would be great.

Thanks,

Mike.

Hi,

i would invoke the ndmpcopy with "-d" switch (debug) and see what happens on the console. Ndmpcopy displays a lot of info during runtime so it is best to just read the output.

Thanks Jakub,

Have kicked it off and will check the results - I take it the "rdfile /etc/log/ndmpcopy.20110518" on the source controller is the only log files which can be used to check if successful or not?  What about Filerview on the source/ target?

Thanks again.

There are two operations the ndmpcopy kicks off when you invoke the command. One is dump & other is restore. The entry for dump & restore gets logged into /etc/backup file. You can always validate the status of the dump & restore in this file. If any of the operation(Dump or Restore) got failed that implies your ndmpcopy was not successful.

I discovered the same problem and found the Bug 357676:

So the ndmpcopy command is successfully executed.
