Known Issues

The adapCfg.h file

You may need to modify the adapCfg.h file after installing the driver. You might also need

to modify the file if the hardware configuration changes, e.g., by adding additional disk

drives to the Fibre Channel interface.

adapCfg.h - Configuration header file specifying tunable parameters for LightPulse

adapters attached to the host machine; this file is located in /opt/lpfc/conf.

Configuring this file is discussed in greater detail in the Configuration manual.

Discovering Disk Drives

To list all the SCSI devices discovered by the lpfc driver, or to list newly attached

devices, enter:

ioscan -fkC

disk

Sometimes, the driver recognizes disk drives at boot time but you won't be able to

use those drives because special file entries for them do not exist. To create these

special files, run:

insf -

Ioscan on 64-bit HP-UX 11i

If the ioscan does not report the software state correctly for lpfd (Pseudo HBA) and

devices attached to it, the I/Os are still sent to those devices. You may be required

to run ioscan multiple times to report the software state correctly.

FCP - Different SCSI Target IDs on Different Hosts

A Fibre Channel target is assigned its D_ID at loop initialization time; the SCSI

target ID for that target is assigned by the device driver when the device is first

discovered. It is possible for the D_ID to change between one loop initialization and

the next. Every time a system boots or a target is added to, or removed from, the

Fibre Channel, the loop will be re-initialized. After a system has booted, it will

maintain a constant view of the same target ID because the driver software remaps
