SuperCluster - Avoiding system/pools maintenance state when modifying zone pool CPU count after using setcoremem (Doc ID 1991360.1)

Last updated on MARCH 23, 2016

Applies to:

Oracle SuperCluster M6-32 Hardware - Version All Versions and later
SPARC SuperCluster T4-4 - Version All Versions and later
Oracle SuperCluster T5-8 Hardware - Version All Versions and later
Oracle SuperCluster T5-8 Full Rack - Version All Versions and later
Oracle SuperCluster T5-8 Half Rack - Version All Versions and later
Oracle Solaris on SPARC (64-bit)

Goal

When the number of CPU-cores available in a SuperCluster Domain is reduced, care must be taken if this Domain is hosting Solaris Zones with CPU-resource pools. The size of the CPU-resource pools used by the Zones must be adjusted accordingly or the pools service (a.k.a. SMF system/pools service) can end up in maintenance state. This document provides instructions on how perform such a modification flawlessly.

On SuperCluster the number of CPU-cores available in a Domain is adjusted with the setcoremem tool.
