Unable to discover the newly assigned LUNs using SCSI bus re-scan

Solution Verified - Updated -


  • New LUNs do not appear even after SCSI bus re-scan using following commands:

    $ rescan-scsi-bus.sh
    $ for i in $(ls /sys/class/scsi_host) ; do echo "- - -" > /sys/class/scsi_host/$i/scan ; done

    We even tried LIP reset using following command, but the new LUNs do not appear until reboot:

    $ echo 1 > /sys/class/fc_host/host2/issue_lip
