Known Issues | 41
 Error, miscellaneous messages logged after successful NetBackup migration.
Message similar to the following are logged in the debug log after a successful migration
with NetBackup 6.5:

(errno=-1).
These messages are benign and can be ignored. (TL-2347)
 The hsm_summary_limit configuration parameter is not used. This parameter
should not be used. (TL-2272)
 Unable to unmigrate a pool. You cannot unmigrate the cartridges in a pool by selecting
the pool; you must select individual cartridges. (TL-0386, TL-8114, TL-5997, TL-7586)
Remote export
 When configuring a remote export, the directory specified by the
rep_source_tmp parameter must exist or the remote export job will fail. The
remote job fails with the error: “Cannot create source temporary directory.” (TL-8374)
 Failed Remote Export job does not send an e-mail alert. (TL-7212)
 Remote export allows the same virtual tapes to be exported to multiple pools.
This occurs by starting a job targeting one pool and then creating a second job with the
same virtual tapes and targeting a different pool. Jobs can be created to make duplicate
virtual tapes, but this should be avoided since the duplicates will be confusing and can
cause VTS not to function properly. (TL-7247)
Backup management application support
 A backup may fail when using Netbackup with a VTL consisting of a MSL6000
and Ultrium 1 drives. The VTL will mount the drive but data is never written to the
tape. (TL-4533)
WORKAROUND: Chan
ge the tape drive to another drive type supported by MSL6000
(ex: SDLT, DLT7000, or Ultrium3).
 Restoring an entire backup using ARCServe succeeds, but restoring individual
files fail. Restoring an entire backup consisting of a multi-tape spanned backup succeeds,
but restoring individual files fail. The error reported is “Invalid file signature
0c00000000”.(TL-7725)
 Backup Exec tape capacity is not correct with MSL6000 and SDLT drive. Backup
Exec reports the wrong tape capacity when connected MSL6000 and SDLT drive. An
Ultrium 3 drive should be used in the MSL6000 if Backup Exec is used on the initiating
server. (TL-7940)
