清除磁盘上的scsi pr锁
查询磁盘上是否有锁,如下图所示,有一个锁,key是0x3943d99f0001734d
[root@localhost ~]# sg_persist -r /dev/sdb DotHill DH3000 G22x Peripheral device type: disk PR generation=0x521, Reservation follows: Key=0x3943d99f0001734d scope: LU_SCOPE, type: Write Exclusive, registrants only
如果有锁,解决方法是,在另外一个机器上,先注册一个锁,然后解除你注册的锁。这样磁盘就放出来了
注册锁(123abc这个ID可以自己随意起一个)
[root@localhost ~]# sg_persist --out --register --param-sark=123abc /dev/sdb DotHill DH3000 G22x Peripheral device type: disk
取消注册锁
[root@localhost ~]# sg_persist --out --param-rk=123abc --clear /dev/sdb DotHill DH3000 G22x Peripheral device type: disk
再次查询确认是否还有锁
[root@localhost ~]# sg_persist -r /dev/sdb DotHill DH3000 G22x Peripheral device type: disk PR generation=0x523, there is NO reservation held
