NAME

dlf — download firmware to an HP SCSI disk array

SYNOPSIS

dlf -f firmware_file device_file

DESCRIPTION

dlf downloads a new set of controller firmware to the HP SCSI disk array associated with device file device_file. The firmware_file must be a binary file with a special format.

RETURN VALUE

dlf returns the following values:

0

Successful completion.

-1

Command failed (an error occurred).

ERROR MESSAGES

Errors can originate from problems with:

dlf
SCSI (device level) communications
system calls

Error messages generated by dlf:

usage: dlf -f <firmware file> <special>: An error in command syntax has occurred. Enter command again with all required arguments, in the order shown.
dlf: Binary file has bad format: The binary file could not be read in properly by the utility.
dlf: device busy: To ensure that dlf does not modify a disk array that is being used by another process, dlf attempts to obtain exclusive access to the disk array. If the disk array is already opened by another process (for example, LVM — the Logical Volume Manager), a ``device busy'' error message is returned by the driver. To eliminate the ``device busy'' condition, determine what process has the device open. In the case of LVM, it is necessary to deactivate the volume group containing the array before configuring the array (see vgchange(1M)).
dlf: LUN # too big: The LUN number, which is derived from the device file name, is out of range.
dlf: Not a raw file: Utilities must be able to open the device file for raw access.
dlf: Not an HP SCSI disk array: The device being addressed is not an
dlf: Transfer length error: The amount of data actually sent to or received from the device was not the expected amount. HP SCSI disk array.

SCSI (device level) communication errors:

Sense data associated with the failed operation is printed.

Error messages generated by system calls:

dlf uses the following system calls:

malloc(), free(), stat(), open(), close(), fopen(), fclose(), read(), write(), and ioctl().

Documentation for these HP-UX system calls contains information about the specific error conditions associated with each call. dlf does not alter the value of errno. The interpretation of errno for printing purposes is performed by the system utility strerror().

EXAMPLES

To download the special-format binary file new_firmware to the HP SCSI disk array /dev/rdsk/c2t0d0 on a series 800:

dlf -f new_firmware /dev/rdsk/c2t0d0 

DEPENDENCIES

The HP C2425 and HP C2427 disk arrays are only supported on Series 700 systems running HP-UX version 9.0X.

The HP C2430 disk array is supported on Series 700 and 800 systems running HP-UX versions 9.0X and 10.0X.
