Increased Boot Time with Unconnected fcd HBA Ports
System boot time will be increased if there are unconnected fcd HBA ports (i.e., HBA ports
controlled by the fcd driver).
This happens because an ioscan is performed as a part of the boot process for HP-UX .
When an ioscan is performed for the first time for an fcd HBA port, the fcd driver waits
for 21 seconds before declaring the port offline.
This is only an issue during boot, because at boot time the HBA ports are scanned
sequentially. After boot, the HBA ports are scanned in parallel, using kernel threads.
The delay observed during boot will be around N*21 seconds, where N is the number of
unconnected fcd HBA ports.
Corrective Action:Two workarounds are available for this issue:
1.
Attach loop back hoods to all of the unconnected HBA ports. The loop back hoods will
cause the unconnected HBA ports to come online in a private loop topology.
2.
Install the product bundle, mtIOScan, that enables boot time kernel threads. This will
reduce the overall boot delay due to unconnected ports to 21 seconds. This product can
be obtained from www.software.hp.com
