I have been struggling with this problem off and on for two weeks. I have one 
Networker server that runs all our NDMP backups with 3 Isilon clusters and 3 
NetApp clusters. We're running on Solaris 10 on Sun SPARC. The Isilons are 
backed up using FC LTO tape drives connected using Isilon Backup Accelerators. 
The NetApps are backed up using directly-connected FC LTO tape drives.

We were running Networker 7.6.2.4 but have upgraded to 7.6.3.3 at request of 
EMC Tech Support. All the backups run as scheduled via NMC, load the first tape 
for each backup and then most of the time, they fail to request/load any 
follow-on tapes. Oddly enough, the Index group has the same problem. I can get 
the backups to start loading tapes by stopping NW, clearing /nsr/tmp, deleting 
/nsr/res/jobsdb and starting the backups again. But again, after the first tape 
for most groups, they never load another. Few backups complete and since you 
cannot restart direct NDMP backups, any unfinished backups are useless. There 
are no error messages in daemon.log nor syslog even after turning on debug in 
Networker.

 I don't expect a solution but was more interesting in seeing if others were 
have the same or similar problem. Thanks.
