[Pacemaker] Help with scsi_reservation on pacemaker

[Vit Pelcak]

Hi people.

I'd like to ask you for help with some problem.

I have to test scsi_reservation in pacemaker.

Currently, I have two operating systems in vmware + 2 shared disks set
with scsi_reservation. On each shared disk there is lvm with ext3. Those
are /dev/datab/datab and /dev/datac/datac.

For configuration I got this xml from colleague:
<resources>                                       
      <primitive class="ocf" id="primitive-scsires" provider="heartbeat"
type="scsi2reservation">
        <meta_attributes
id="primitive-scsires-meta_attributes">                                
          <nvpair id="nvpair-e6001b42-2803-42b8-98ef-ab00d71a9495"
name="target-role" value="Stopped"/>
       
</meta_attributes>                                                                            

        <operations
id="primitive-scsires-operations">                                                

          <op id="primitive-scsires-op-monitor-20" interval="20"
name="monitor" timeout="20"/>        
       
</operations>                                                                                 

        <instance_attributes
id="primitive-scsires-instance_attributes">                              
          <nvpair id="nvpair-f67b325b-9114-40cc-8a12-b3eaeed9291e"
name="scsi_reserve" value="/usr/sbin/scsi_reserve"/>
          <nvpair id="nvpair-9aa6969b-e28a-4b51-a827-6831344f2fe3"
name="sharedisk" value="/dev/datab/datab"/>                
          <nvpair id="nvpair-e88e742a-7099-4eab-a03c-e18b6f4d14b5"
name="start_loop" value="10"/>                     
       
</instance_attributes>                                                                                        

     
</primitive>                                                                                                    

</resources>

If I understand it well, this should set one resource /dev/datab. But
how can I add datac resource as depending?

I simply need to test scsi reservation, and I got advised that this is
the way.

If you find (most probably) this description insufficient, feel free to
ask for further info.

Thank you for help.
