Solution
Check the following metalink - Subject: Error - program nmhs is using a deprecated SCSI ioctl, please convert it to SG_IO in /var/log/messages Doc ID: 566547.1 Type: PROBLEM Doc ID: 566547.1 Unpublished Bug 5897089 NMHS USES DEPRECATED SCSI IOCTL nmhs is used by the storage_report_metrics.pl which runs once every 24 hours by default. This script is querying the OS about various devices and mount points. This message is for information only and can be ignored. It is an indication that a future release of SCSI might not support this ioctl call. However, due to the fact that it floods the /var/log/messages file, a fix has been provided. Solution Patch 5897089 is available via My Oracle Support to address this issue.
