Virtual TapeServer 8.2 Release Notes

Known Issues | 47
 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:
Fri Nov 7 14:45:27 2008: [slave_signal_thread 15713] SIGCHLD received
while no active child, ignoring it.
Fri Nov 7 14:45:32 2008: [cli_tape 0x05000107] ERROR UNKNOWN tape
command 0x44 for Id 0
Fri Nov 07 14:46:15 2008: [lsof.pl] Error: lsof.pl /usr/sbin/lsof |
grep "/VAULT00/MAXPOOL/MAX001" 2>&1 failed!, rc=1, error=No system
error detected. Please check application logs for application errors.
(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-386)
Remote export
 Multiple email messages sent per remote export job. VTS sends an email for each
virtual tape that is exported by a Remote Export job. An email message should be sent per
job, not per virtual tape. (TL-7213)
 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)
 No error message if typo in /etc/hosts causes remote export to fail. If there is a
typo in the /etc/hosts file, the destination host is unreachable but there is no notification.
An error message should be generated if this occurs. (TL-6984, EAR 8107)
Backup management application support
 Backup Exec shows standalone VTDs as offline on a change of media. Every time
a new tape is mounted, it is shown as offline in Backup Exec. (TL-7617, EAR 8795)
 Backup Exec incorrectly reports tape capacity with every drive type. Tape
capacity may be incorrectly reported by Backup Exec to VTS. It reports ~98GB for all
drive types. It also reports compression ratios of <6,000,000 to 1. This is because VTS does
not support Capacity Reporting, so Backup Exec estimates the tape size. (TL-7579, EAR
8805)
 Restoring individual files from export that spanned files using CA ARCserve
fails. (TL-6517)
WORKAROUND: Restore the entire backup to obtain the single file.
