Change Device Discovery Delay
This parameter sets a delay to occur after an loop initialization and before a scan is
initiated to discover the target. The default is off or 0 seconds.
Change the default if you have an HP MSA1000 or HP MSA1500 RAID array and if
both of the following conditions exist:

The MSA array is direct connected or part of an arbitrated loop (for example,
daisy chained with a JBOD).

The boot LUN is not reliably discovered. In this case, a delay may be necessary
to allow the array to complete a reset.
Caution: Do not change the delay device discovery time if your MSA array is
connected to a fabric switch. Setting it to any other time guarantees that the
maximum delay time is seen on every loop initialization.
