I have been trying to backup my NetApp /vol/vol0 data to local tape drive. It is around 68GB.
The tape I am using is DLT tape and should be able to handle 70GB data. However, dump always
aborted around reaching 57~58GB data.
Tape drive is attached on NetApp.
1st try to dump /vol/vol0 to local drive (68GB) => dump aborted
2nd try to dump /vol/vol0/home to local tape drive (59GB) =>dump aborted
Any idea?
Here are some info
