When you replace a controller on an array, it may happen that the LUNs on the array are not correctly
presented to the controllers. You can check the LUN presentation using the
/usr/opt/hpls/diags/
bin/controller_check.bash
command, and if necessary, reconfigure the LUN presentations. See
Section 9.29 for information on troubleshooting LUN presentation.
