Last updated on DECEMBER 06, 2021

Applies to:

Solaris Cluster - Version 3.2 to 4.3 [Release 3.2 to 4.3]
Solaris Cluster Geographic Edition - Version 3.2 to 4.3 [Release 3.2 to 4.3]
Oracle Solaris on x86 (32-bit)
Oracle Solaris on x86-64 (64-bit)

Symptoms

This problem only occurs on Intel Xeon processors (Nehalem/Westmere CPU's which have ACPI Power Management feature). This feature allows the operating system to place the processor in low power state (deep C-state) when not in use. This can appear as very long latency on I/O and appear as a hung system.

In case of the Solaris Cluster x86 on such system (e.g: X4470) the following error have been seen:

A) pm_tick delay which can cause a panic
