Fixed In Version: kernel-2.6.18-238.1.1.el5
Doc Type: Bug Fix
Doc Text:
If an error occurred during I/O, the SCSI driver reset the "megaraid_sas" controller to restore it to normal state. However, on Red Hat Enterprise Linux 5, the waiting time to allow a full reset completion for the "megaraid_sas" controller was too short. The driver incorrectly recognized the controller as stalled, and, as a result, the system stalled as well. With this update, more time is given to the controller to properly restart, thus, the controller operates as expected after being reset.
