Changing 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.
If both of the above conditions exist, typically set this parameter to 20 seconds.
However, the delay should be only long enough for the array to be reliably discovered
after a reset. Your value may be different.
To change the delay device discovery value:
1. From the Device Manager screen (Figure 13-2), select the adapter whose device
discovery delay settings you want to change and press <Enter>.
2. From the Emulex Adapter Configuration Main Menu (Figure 13-3), select
Configure HBA Parameters and press <Enter>. The Configure HBA Parameters is
displayed.
3. From the Configure HBA Parameters menu, select Delay Device Discovery and
press <Enter>.
