LPAR Overhead Percent Critical Situation

 

Suggested Actions

LPAR (PR/SM) overhead exceeds the current Critical threshold. Possible causes include saturation of the CPU capacity leading to excessive overhead switching CPUs between LPARs. This can be compounded when there are too many logical processors assigned to an LPAR. IF the PR/SM overhead is confined to one LPAR, consider reducing the number of logical processors in that LPAR.
