fence_scsi is failing on linux guests on wmware

Question

I have a cluster with two nodes. I have checked on both nodes if the disk is supporting;

[root@d-clus1 ~]# /usr/bin/sg_persist -n -i -r -d /dev/sdb
  PR generation=0x1, Reservation follows:
    Key=0xec290000
    scope: LU_SCOPE,  type: Write Exclusive, registrants only
[root@d-clus2 ~]# /usr/bin/sg_persist -n -i -r -d /dev/sdb
  PR generation=0x1, Reservation follows:
    Key=0xec290001
    scope: LU_SCOPE,  type: Write Exclusive, registrants only

I have configured the scsi stonith;

[root@d-clus1 ~]# pcs stonith create scsi fence_scsi pcmk_host_list="d-clus1 d-clus2" pcmk_reboot_action="off" pcmk_monitor_action="metadata" devices="/dev/sdb" meta provides="unfencing" --force

I is successfully started, however both node is reading only its own key;

[root@d-clus1 ~]# /usr/bin/sg_persist -n -i -k -d /dev/sdb
  PR generation=0x1, 1 registered reservation key follows:
    0xec290000
[root@d-clus2 ~]# /usr/bin/sg_persist -n -i -k -d /dev/sdb
  PR generation=0x1, 1 registered reservation key follows:
    0xec290001

And it is causing the failure on fencing. Where is my mistake?
