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 directly 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.
If both of the above conditions exist, typically set this parameter to 20 seconds.
However, the delay only needs be enough for the array to be reliably discovered after a
reset. Your value may be different.
To change the delay device discovery value:
1. On the Boot Configuration menu, select 5. Delay Device Discovery and press
<Enter>. The screen shown in Figure 6-28 is displayed.

2. Use the left /right arrows to select values in 10-second increments and press
