Red Hat Bugzilla – Bug 441640
RHEL 5.1 will incorrectly mark SCSI devices as offline due to improper error handling
Last modified: 2009-01-20 15:21:51 EST
In RHEL 5.1 and the RHEL 5.2 beta if a check condition status is received by the
Linux SCSI stack and it goes into error recovery mode, the resulting sense data
response is handled improperly and will cause the device to be marked offline.
This can occur when SCSI devices are loaded early in the boot process and are
not yet fully able to process a SCSI inquiry command. In RHEL 5.0 this case was
handled properly, but in RHEL 5.1 the response buffer is copied incorrectly
causing a bus reset and the device to be marked offline.
The issue has been confirmed fixed by
with the standard RHEL 5.1 2.6.18-53 source RPM.
