Adding a LUN on RHEL 5

For example, if powermt display lists HBAs 2 and 3, initiate the
scan by issuing the following commands:

echo "- - -" > /sys/class/scsi_host/host2/scan
echo "- - -" > /sys/class/scsi_host/host3/scan

Run powermt display to show the new LUN along with the
associated native devices.

Adding a LUN on RHEL 4

Scan each HBA bus listed in the powermt display by entering the
command:
For Qlogic cards:

echo 1 > /sys/class/fc_host/host<controller>/issue_lip
echo "- - -" > /sys/class/scsi_host/host<controller>/scan

For Emulex cards:
echo "- - -" > /sys/class/scsi_host/host<controller>/scan

Run powermt config to recognize the new LUN and to configure
it.
