Code Load and Code Patch Utility
Use Code Load/Code Patch (CLCP) utility to upgrade the controller software and the
EMU software. You can also use it to patch the controller software. When you install
a new controller, you must have the correct software version and patch number. See
Chapter 3, “Upgrading Controller Software,” page 3–2, for more information about
using this utility.
NOTE: Only COMPAQ field service personnel are authorized to upload EMU
microcode updates. Contact the Customer Service Center (CSC) for directions in
obtaining the appropriate EMU microcode and installation guide.
What BUFFER SIZE, (in BYTES), does
the drive require (2048, 4096, 8192)
[8192]?
HSUTIL detects that an unsupported device has been selected as
the target device and the firmware image requires multiple SCSI
Write Buffer commands.You must specify the number of bytes to be
sent in each Write Buffer command. The default buffer size is 8192
bytes. A firmware image of 256 K, for example, can be code loaded
in 32 Write Buffer commands, each transferring 8192 bytes.
What is the TOTAL SIZE of the code
image in BYTES [
device default ]?
HSUTIL detects that an unsupported device has been selected as
the target device. You must enter the total number of bytes of data
to be sent in the code load operation.
Does the target device support only
the download microcode and save?
HSUTIL detects that an unsupported device has been selected as
the target device. You must specify whether the device supports
the SCSI Write Buffer command’s download and save function.
Should the code be downloaded with
a single write buffer command?
HSUTIL detects that an unsupported device has been selected as
the target device. You must indicate whether to download the
firmware image to the device in one or more contiguous blocks,
each corresponding to one SCSI Write Buffer command.
