10/15/2008 10:56:42 - Error ndmpagent (pid=26662) NDMP backup failed, path = /vol/fvol3/ndmp_test
EXPLANATION:
The buffer space to be used for getsockopt() is 4 times the size of data buffers. If 4 times the size data buffers is more than what setsockopt() can handle at the operating system level, backups will fail with this error.
SOLUTION:
Check for the presence of /usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS or /usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS_DISK on the NetBackup server. If these are present, and either of them is set to a high value, create this file for NDMP backups /usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS_NDMP and use a lower value (e.g. 262144) that the operating system can handle.

Note: Under most circumstances, SIZE_DATA_BUFFERS_NDMP will impact Remote NDMP backups. Remote NDMP backups occur when the tape device used for the NDMP backup is attached to the NetBackup Media Server and not connected to the NDMP host.
Also consider the following:
In NetBackup 7.0.1, when SIZE_DATA_BUFFERS_NDMP is set to a different value than SIZE_DATA_BUFFERS, multiplexed backups may fail due to coredumps from bptm and ndmpagent, while backups which succeed may not be restorable under certain conditions.
Note: This issue is resolved in the latest versions of NetBackup 7.1 and 7.5. Refer to the
Upgrade Portal for information on upgrading.
