The maximum number of compute node path information items that can be registered is 4,096 per compute node, and 255 per compute port. The maximum number of path information items per compute node changes depending on the number of storage nodes, the number of storage node compute ports, and the number of initiators registered in a compute node.
Depending on how parameters portId and hbaId are specified, the following are possible:
-
Both portId and hbaId are omitted: All the initiators of the intended compute node are allocated to all the compute ports.
-
Only hbaId is specified: The specified initiator is allocated to all the compute ports.
-
If you have changed the path information of a compute node, perform a rescan of the storage in that compute node before you start I/O operations.
-
If using VMware ESXi as a compute node, set up a path between the compute node and all computer ports. Unless all paths have been set, some volumes might be invisible from a compute node.
If not using VMware ESXi as a compute node, it is also recommended to set up a path between the compute node and all computer ports to prevent I/O performance from being deteriorated.

Required role: VpsStorage
-
The information about the intended compute node and its initiator must be registered beforehand.
