Selecting a Server to Manage a Controller
To manage and monitor an array, the agent needs to have access to a host logical unit number (LUN) mapped to a partition of a logical drive assigned to the primary controller of the array. The agent ignores all host LUNs mapped to a partition of a logical drive assigned to a secondary controller in a redundant configuration of an array. If the same array is connected to multiple servers, it is possible to have the agent running on each of these servers trying to manage and monitor the same array. Due to a restriction on monitoring commands to be sent to the array controller by only one server at a time, some monitoring commands might fail if sent simultaneously by multiple servers. This could cause inaccurate reporting or the processes to stop responding. To prevent this from happening, the agent can be configured to enable/disable array monitoring on a server. CAUTION: Sun StorEdge Configuration Service can monitor and manage up to 32 arrays at one time. However, console
response time can decrease as the number of arrays increases.
Assigning a Controller Through the Console
This enables the selected server to manage an array controller. It
also disables all other servers listed on the list box from managing
the same array.
The main window shows the array controller device icon only under
the server where the monitoring is enabled for this array.
