Unmounted tape (Storedge L8/Linux)

Question

Could anyone say why my tape in robot(StorEdge L8) always went to unmount state :
1 ) I mounted tape1
ob> lsdev -Hm
library lib1 in service
drive tape1 in service read obtar RMANX-000002
2 ) Then I started rman backup
connected to target database: BACKUPDB (DBID=3985456081)
using target database control file instead of recovery catalog
RMAN> run {
2> allocate channel oem_sbt_backup1 type 'SBT_TAPE' format '%U';
3> backup database;
4> delete noprompt obsolete recovery window of 31 days device type 'SBT_TAPE';
5> }
6>
7>
allocated channel: oem_sbt_backup1
channel oem_sbt_backup1: sid=147 devtype=SBT_TAPE
channel oem_sbt_backup1: Oracle Secure Backup
Starting backup at 15-APR-08
channel oem_sbt_backup1: starting full datafile backupset
channel oem_sbt_backup1: specifying datafile(s) in backupset
input datafile fno=00001 name=/opt/oracle/oradata/BACKUPDB/system01.dbf
input datafile fno=00003 name=/opt/oracle/oradata/BACKUPDB/sysaux01.dbf
input datafile fno=00004 name=/opt/oracle/oradata/BACKUPDB/users01.dbf
input datafile fno=00002 name=/opt/oracle/oradata/BACKUPDB/undotbs01.dbf
channel oem_sbt_backup1: starting piece 1 at 15-APR-08
it stopped in this point
3) If I look into devices and jobs a see
ob> lsdev -Hm
library lib1 in service
drive tape1 in service unmounted
ob> lsjob
Job ID Sched time Contents State
preauth_user/9 none database BACKUPDB (dbid=3985456081) processed; Oracle job(s) scheduled
preauth_user/9.1 none datafile backup pending resource availability
ob>
4) Ok - I mounted it again
ob>mountdev --write tape1
ob> lsdev -Hm
library lib1 in service
drive tape1 in service write obtar RMANX-000003
5) And run
ob>runjob device tape1 now preauth_user/9.1
it looks good good :
channel oem_sbt_backup1: finished piece 1 at 15-APR-08
piece handle=7ljdskuk_1_1 tag=TAG20080415T121100 comment=API Version 2.0,MMS Version 10.2.0.0
channel oem_sbt_backup1: backup set complete, elapsed time: 00:08:45
Finished backup at 15-APR-08
Starting Control File and SPFILE Autobackup at 15-APR-08
....but it again stopped, 'cos
6) ob> lsjob
Job ID Sched time Contents State
preauth_user/10 none database BACKUPDB (dbid=3985456081) processed; Oracle job(s) scheduled
preauth_user/10.1 none controlfile autobackup pending resource availability
ob> lsdev -Hm
library lib1 in service
drive tape1 in service unmounted
ob>
What I do wrong ?

PS: I undestand that it is closing OLD VID and create new VID after each session, but what I have to change in configuration?
And what mean this error :
