Release Notes v4.0.00

Important: Due to major technical improvements, versions 3.1.00 (or older) and 4.0.00 are not compatible. They cannot be operated simultaneously and no upgrade cannot be performed. Note that the entire configuration of the 'product name' will be lost when upgrading from 3.1.00. To use version 4.0.0 safely, we strongly recommend you to perform the following operations:

What's New

•	The product now integrates Hardware Monitoring (batteries, fans, Ethernet ports, power supplies). Importing BMC ProactiveNet Performance Management - Hardware is no longer required to monitor basic component health.

•	LUNs and Volumes Monitoring: it is now possible to disable the monitoring of all the volumes of a system to limit the number of instances created and therefore reduce the system resource consumption.

New Attributes and Metrics

•	The Spare Disk Group attribute has been implemented in the EMC Disk Group monitor type to report on the number of spare disks available in the group.

•	The PortCount attribute has been added to the EMC Disk Array and EMC filer monitor types to report on the number of ports in these devices.

•	FC and Ethernet ports traffic monitoring on EMC CLARiiON and VNX series is supported. New metrics are now available (Input/Output Operations per Second (IOPS) metrics, transferbyterates, etc.).

•	The monitoring solution now reports on controllers' Cache Hit Ratio to provide the percentage of requests that are successfully served by a cache (See EMC Controller Class).

•	The monitoring solution now reports on the following new attributes for the Controller, Volume and Disk Array monitor types:

Attribute	Description
Read Operation Rate	Number of read operations per second
Write Operation Rate	Number of write operations per second
Operation Rate	Total number of operations per second

Changes and Enhancements

•	Report Scheduling: Updating a policy that set the scheduling options of a report purges the report configuration variables and stops the report process.

•	Device IDs have been improved to provide more meaningful information to BMC ProactiveNet Performance Management - EMC Storage Monitoring 4.0.00 users. IMPORTANT: Consequently, attributes history will be lost when upgrading to version 4.0.00. volume name (volume type)

•	The method used to retrieve the volume type, which is displayed between brackets next to the volume name, has been modified to provide more precise information. Possible values for the volume type are: Traditional, VAULT, SFS, DATA, SAVE, Virtual, Thin.

•	BMC ProactiveNet Performance Management - EMC Storage Monitoring 4.0.00 collects non performance data even though the statistics logging is disabled on the disk array.

Fixed Issues

•	The method used by the monitoring solution to calculate the disk size has been improved to provide an exact and accurate information in the disk label.

•	BMC ProactiveNet Performance Management - EMC Storage Monitoring 4.0.00 now supports unlimited debug file size. In previous versions, the debug file size was limited to 500 MB.

•	The Consumed Capacity and Consumed Capacity Percentage of the volumes were incorrectly reported when FAST VP Policies were enabled (Tier mode). In such a configuration, the connector only took into account the first storage pool instead of all the storage pools to which the volume belonged.

•

In order to report more accurately on the actual available capacity of a disk array, the calculation method used to determine the Available Capacity of the EMC Disk Array monitor type has been modified. The Available Capacity attribute now reflects the capacity available in storage pools plus the total space available for storage pool creation.

•	BMC ProactiveNet Performance Management - EMC Storage Monitoring 4.0.00 now properly reports connectivity issues with the SMI-S providers in a timely manner.

Known Limitations
