SCSI Reservation
SCSI reservation agents manage LUN based locking using the SCSI3-PR (Persistent Reservation) protocols that shared storages support such as SAN.This function can prevent data losses when no nodes in a cluster know the status of other nodes.
Shared disk DR
It is the mirror set of shared disk in a cluster to an off-site DR node through WAN, so that mission critical service will be always-on from disasters.
...
Each resource type has a specific attribute value.
For an example, when compare to NIC and mirror disk, each service has different characteristics and has specific monitor interval, online/offline timeout and managed policies
In addition, even in the environment where high availability clusters are configured, if the network condition is not good, you need to adjust the monitoring timeout.
Depending on the requests, you can change the attribute of each type.
Resource type attribute can be checked in the resource type attribute menu of the MCCS web console.
