Does not sound right from what EMC comments, it's a normal behavior of
NDMP restore to lay down the file system and all file names with 0KB as
size, then it will proceed and restore the files correctly after few more
minutes ( Depending on VTL vs physical tape being read).
What exactly is your NDMP configuration ( app parameters) & Networker
client parameter ? have you specified recover storage node field ? This
should math your client name ( since it's a SN).Does this parameters
confirm to what is in the Networker guides ?
I am listing what a sample Netapp NDMP client Apps & Module parameters are
( This options will differ based on your environment), also make sure you
have correct password etc supplied at the ndmp client level.
HIST=y
UPDATE=y
DIRECT=y
EXTRACT_ACL=y
UTF8=y

Thanks saiyed for ur reply. But we had many tiomes succesful restore from
the filer before starting ndmp backups also. We were mapping the drives
onto another client and backups were done. But the backups were slow with
this. thats why we enabled the NDMP backups. But now we could really speed
up the backups. but now restore is not working. While restoring a file of
1 mb it takes almost 30 min and finally we would be able to see the
restored file and folder. But the size of the restored files remains 0KB.
So i dont even think its a permission issue as you said ...
May be sum where we have to add sum parameter. We applied the fix given by
emc. The workaround what they told was its a known issue and told us to
put the NDMP parameter NO for all the client instances except for the one
we are restoring. But still there is no solution for this...
Any ideas ?
rgds,
kv
