This resource agent manages SCSI persistent reservations on multipath devices.
"mpathpersist" from multipath-tools is used, please see its documentation.
Should be used as multistate (Master/Slave) resource
Slave registers its node id ("crm_node -i") as reservation key ( --param-sark ) on each device in the params "devs" list.
Master reservs all devices from params "devs" list with reservation "--prout-type" value from "reservation_type" parameter.
Please see man sg_persist(8) and mpathpersist(8) for reservation_type details.

"master_score_base" value is used in "master_score" calculation:

master/slave decreases/increases its master_score after delay of "master_score_delay" seconds

this can work only if the master_score_delay is bigger then monitor interval on both master and slave
