Release Notes for v4.0.00

Home  Previous  Next

warning Upgrading from an older version of EMC Disk Arrays KM for PATROL to version 4.0.00 of the KM is not possible. For more details, please refer to the Packages section of the documentation.

What's New

New Monitoring Features

The product now integrates Hardware Monitoring (battery, fans, Ethernet ports, power supplies). Loading Hardware Sentry KM is no longer required to monitor basic component health.
EMC Disk Arrays KM for PATROL now supports EMC Celerra storage systems (Support of both SAN and NAS).
EMC Disk Arrays KM for PATROL now monitors snap storage pool.
A new application class SEN_EMC_FCPORT_CONT has been implemented to regroup the FC ports of controllers.
FC and Ethernet ports traffic monitoring on EMC CLARiiON and VNX series is now supported.
The product now reports on controllers' Cache Hit Ratio to provide the percentage of requests that are successfully served by a cache (See SEN_EMC_CONTROLLER_SYMM application class).
The product now supports dynamic tiering configurations (FAST VP policies in EMC Symmetrix VMAX).
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.
The KM now supports unlimited debug file size. In previous versions, the debug file size was limited to 500 MB.

New Parameters

The SpareDiskGroup parameter has been implemented in the EMC Disk Group application class to report on the number of spare disks available in the group.
The PortCount parameter has been added to the SEN_EMC_ARRAY and SEN_EMC_FILER classes to report on the number of ports in these devices.
New metrics are now available (Input/Output Operations per Second (IOPS) metrics, transferbyterates, etc.).
The monitoring solution now reports on the following new parameters for the Controller, Volume and Array classes:




Number of read operations per second.


Number of write operations per second.


Total number of operations per second.

The StoragePool InfoBox has been added to the SEN_EMC_VOLUME_CLAR and SEN_EMC_VOLUME_SYMM application classes to indicate the number of disk drives configured with a particular storage profile.

Changes and Enhancements

Device IDs have been improved to provide more meaningful information to EMC Disk Arrays KM for PATROL users.
KM Reinitialization: A backup of the PATROL Agent configuration is now performed and saved in the $PATROL_HOME/config directory before a reinitialization of the KM.
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.
The method used by the KM to calculate the disk size has been improved to provide an exact and accurate information in the label.
EMC Disk Arrays KM for PATROL collects non performance data even though the statistics logging is not activated.
The StoragePool InfoBox of the SEN_EMC_PHYSICALDISK_CLAR and SEN_EMC_PHYSICALDISK_SYMM application classes now show the associated storage pool instance name instead of the Pool ID.
The Speed Infobox of the SEN_EMC_FCPORT application class now displays when the port speed is equal to 0 corresponding to a disabled port.

Fixed Issues

The number of disks displayed in the InfoBox of an Array instance is now computed according to the number of physical disks created under this same array.
Removing the monitoring of at least one volume, using the Remove KM Command, led to an erroneous calculation of the SubscribedCapacity and SubscribedCapacityPercentage parameters for the related Storage Pools.
The Restore Monitoring KM command listed devices to restore even when the SMI-S Provider was removed from the monitored environment.
The KM now properly reports connectivity issues with the SMI-S providers in a timely manner.
In order to report more accurately on the actual available capacity of a disk array, the calculation method used to determine the Available Capacity parameter of the EMC Disk Array class has been modified. The AvailableCapacity parameter now reflects the capacity available in storage pools plus the total space available for storage pool creation.
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.


Report Scheduling: Reports were still generated even though the report generation was stopped or its configuration was modified.
Scheduling daily reports now generates only one report a day.

Known Limitations

The capacity of FAST VP volumes (dynamic tiering) is reported as fully subscribed in each of the underlying storage pools. If, for example, a 1TB volume consumes 100GB of an SSD pool and 500GB of a SATA pool, both pools will be considered as subscribed for 1TB. While not false, this will cause the subscription of a pool and of the entire storage system to be greater than what has been actually subscribed by the hosts.
