HI Mike, Yes, its a RHEL 6.3 kernel.
I'm running target faults (i.e. reboot the targets) so that I fail the Active-optimized paths and IO switches to Active Non-Optimized paths. During this fault exercise i'm observing few IO outage. So I'm expecting the iSCSI error handler to kick-in whenever the target is slow in responding to any IO request or when the IO paths are switching back and forth b/w AO & ANO path. Is my understanding right here? With few older kernel releases I was seeing error handling messages during similar exercise. Is there any dependency on rsyslog settings? Should I check for any particular setting in /etc/rsyslog.conf file?
