48 Understanding Dell Server Management Pack Suite Operations
NOTE: Create RunAsAccount for CMC slots discovery with simple, basic, or digest
authentication only. For more information, see Configuring the Dell Chassis
Management Controller Management Pack for Discovering Server Modules and
Chassis Slot Summary
.
NOTE: Only one set of credentials is considered for discovering CMCs in SCOM
SP1 and SCE SP1. SCOM 2007 R2 and SCE 2010 allow greater flexibility where the
credentials can be specified for group or instance level.
NOTE: The iDRAC firmware of the Modular systems should be compatible with the
CMC firmware, failing which, the Service Tag is displayed as "Not Available" and the
Chassis-Blade correlation may not be possible.
CAUTION: The Chassis Modular Server Correlation Utility discovers the
correlation between the Dell CMCs or DRAC/MCs discovered by the CMC
management pack and the Dell modular systems discovered by the Server
management pack. To discover the correlation, the utility queries the Root
Management Server (RMS). When you are monitoring a large number of chassis
and modular systems, the number of queries to the RMS increases and this results
in high CPU utilization on the management server that manages the CMCs or
DRAC/MCs. The CPU utilization comes down after the correlation is complete. This
behaviour occurs in every discovery cycle set in Dell CMC Chassis to Modular
Server Correlation Discovery or the Dell DRAC/MC Chassis to Modular Server
Correlation Discovery.
