Bug 1267131

Summary:	Multipath is not correctly identifying iscsi devices, and misconfiguring them.

Fixed In Version:	device-mapper-multipath-0.4.9-77.el7_1.2	Doc Type:	Bug Fix
Doc Text:	Cause: To determine if a device was an iscsi device, multipath was checking the "tgtname" sysfs file. The file name has changed to be "targetname". This meant that multipath was not correctly identifying iscsi devices as such, and would not use the iscsi specific configuration functions. Consequence: Multipath would not correctly set fast_io_fail_tmo for iscsi device. Fix: Multipath now checks for both "tgtname" and "targetname" Result: Multipath correctly identifies iscsi devices as such, and configures them correctly.	Story Points:	---
