Flood of IOC errors with LSI Logic Fusion-MPT controller (mptspi)

This document (7001761) is provided subject to the disclaimer at the end of this document.

Environment

Novell SUSE Linux Enterprise Server 10 Service Pack 2

Situation

On SLES10 SP2 servers with LSI Logic Fusion-MPT SCSI controllers, a flood of IOC messages in /var/log/messages can sometimes be encountered. The following are samples of these messages:

Jul 31 14:56:54 fs01 kernel: Fusion MPT misc device (ioctl) driver 3.04.06-suse

Resolution

These messages are the result of loading the mptctl module. This module provides ioctls to management programs distributed by LSI, and is not required by SLES.

Unloading the mptctl module will resolve the problem for the current session. To ensure the module is not loaded during subsequent reboots, add the following line to the /etc/modprobe.conf.local file:

  install mptctl   /bin/true

Uninstalling the mpt-firmware RPM will also resolve this issue.
