Patch content

Connectors for SMI-S Disk Arrays and Libraries. Improved collection PSL library.

Should you install this patch?

Apply this patch if you are monitoring large SMI-S Disk Arrays or Libraries (notably EMC Symmetrix). The discovery fails to complete and consumes the equivalent of 100% of the time on one processor (i.e. 50% on a dual core system, 25% on a quad core, etc.). "Couldn't obtain lock" error messages appear in the System Output Window of the PATROL Console.

What does it fix?

Improves discovery and collection routines to more efficiently process the large list of components contained in these larger disk arrays. The complexity of the discovery algorithm is O(N), down from O(N2), where N is the total number of managed components in the disk array.

How to install the patch?

Copy the following files (MS_HW_SMISLibrary.hdf, MS_HW_SMISDiskArray.hdf, MS_HW_collect.lib) to the $PATROL_HOME/lib/MS_HW_hdf directory on the managed server. Restart the PATROL Agent.
