在存在活动的SPC-3注册时收到传统的SPC-2预约/发放，返回RESERVATION_CONFLICT

我有2个iSCSI备份。

我尝试确定共享磁盘是否可以用作tiebreaker磁盘 。 为此，我使用IBM的一个工具在iSCSI启动器上运行以释放预留：

 [root@softiwarp-1 ~]# /media/distr-ro/db2/10.5/linuxx64/v10.5fp7_linuxx64_universal_fixpack/universal/./db2/linuxamd64/install/tb_break -u -t SCSI WWID=`scsi_id -g -u /dev/sdd` Initializing SCSI tie-breaker (WWID=36001405bb9264c9e8c145429dbc76047) Releasing tie-breaker (WWID=36001405bb9264c9e8c145429dbc76047) tb_release status 0 (errno=0) [root@softiwarp-1 ~]# /media/distr-ro/db2/10.5/linuxx64/v10.5fp7_linuxx64_universal_fixpack/universal/./db2/linuxamd64/install/tb_break -u -t SCSI WWID=`scsi_id -g -u /dev/sde` Initializing SCSI tie-breaker (WWID=36001405ed3a0a03628a4108bc3e24a82) Releasing tie-breaker (WWID=36001405ed3a0a03628a4108bc3e24a82) tb_release status -1 (errno=25) 

对于其中一个磁盘，命令成功。 另一个失败，在我看到的dmesg目标
