EMC Disk Arrays Monitoring First Screenshots
September 10, 2010- Status: Ongoing development
- Expected release date: October 2010
In order to facilitate the servers management, EMC Disk Arrays KM for PATROL will provide, among many other functionalities, the following three useful features:
Lun's Mapping Table
Over time, as servers connected to a SAN get decommissioned, administrators find an increasing number of unmapped LUNs, or volumes that are no longer used by any server. These LUNs, while unused, still occupy disk space in the disk array. Being able to identify such unmapped LUNs and reclaim the disk space uselessly consumed by these LUNs will help administrators avoid unnecessary upgrades and extensions of their disk arrays.
Lun's Owning Processor Table
Designed to help administrators identify load balancing issues, this feature reports on the name of the controller handling I/Os for each LUN of the managed environment. When a LUN is not actually handled by its normal (default) storage processor, the name of the default controller is indicated as SP_B (default: SP_A)".
Search WWN
Every component is uniquely identified on the SAN with an obfuscated series of letters and digits called a WWN: LUNs, storage groups, disks, fiber ports, arrays, servers, etc. Retrieving a device corresponding to a WWN found in error log or any other administration GUI is a nightmare for SAN administrators. The Search WNN feature has been design to easily find any component based on its complete or partial World Wild Name.
