Without knowing details about how you have things configured, it's dangerous for us to assume things. While it *SHOULD* work, you are (still), in a supported environment. You are paying for support from RedHat and EMC, and they can answer this with far better clarity than we can here.
I have been working in redhat provided drivers with multipathing not Qlogic provided + powerpath, I use the below commands to detect a LUN and configure the device... But in powerpath i dont have much experience that why i posted my doubts here.. If you know the answer for my question kindly share it..
1) Issue LIP Reset
for i in /sys/class/fc_host/host*; do echo "1" > $i/issue_lip; sleep 5; done
- Verify that LIP reset worked
- Output in syslog should display:
.....LIP reset occured... -> This indicates the LIP reset completed.
grep -i lip /var/log/messages | tail -10
2) Rescan SCSI bus
for i in /sys/class/scsi_host/host*; do echo "- - -" > $i/scan; sleep 5; done
