Datasheet

Using the AIX Diagnostics via command line input.

The command line to download microcode will use the highest level of microcode in the /etc/microcode directory for the

device selected. To use the AIX 5.1 diagnostics command line input for microcode download do the following:

diag -c -d rmt0 -T "download" (enter)

Sample Dsdata file

Dsdata files are unique to each drive.

The following is the dsdata file for the 60GB 8mm tape drive for use with the program "Genucode" or the AIX 5.1

diagnostics:

* Mammoth 2 Dsdata File 60GB 8mm Tape Drive

* May 9, 2003 V:01

* dsdata - Drive Specific Data for microcode download

* The dsdata file is used by both AIX Diagnostics, level 5.1 and higher,

* and the separate program "Genucode" available from IBM external WEB

* site.

* Format of the data:

* LINE1: blocksize(3-hex) buffer_offset(3-hex) binary_filesize(decimal)

* LINE1:(continued) timeout_value(decimal) write_buffer_type{4 or 7}

* LINE1:(continued) {PdDVLn string found from odmget -qname=devicex CuDv}

* LINE2: (vendorname) inquiry_page page_offset field_length value

* Note:

* "Genucode" requires the firmware level in line 3 to match the

* firmware level you wish to download.

* Naming conventions for Genucode are:

* Microcode file: /tmp/Mammoth2.07pR.A1700295

* dsdata file: /tmp/dsdata

* AIX Diagnostics "Microcode Download" does not require the firmware

* level in line 3 to match the firmware level you wish to download.

* Naming conventions for AIX diagnostics are:

* Microcode file: /etc/microcode/Mammoth2.A1700295.07pR

* dsdata file: /etc/microcode/Mammoth2.A1700295.dsdata

* LINE3: (firmware level) inquiry_page page_offset field_length value

* LINE4: (loadid) inquiry_page page_offset byte_length hexvalue

SCSD Tape/Optical Ucode Download Utility

Genucode: SCSI microcode download utility for SCSD devices

Genucode is a program that can be used to download microcode to tape drives and other devices attached to an eServer

pSeries or RS/6000. The devices Genucode supports use the Self Configuring SCSI Device driver(SCSD) on these systems.

Information about using Genucode

Note: Do not power the tape drive off immediately after the microcode says it is complete as the tape drive may be still

doing internal processing that will take a few minutes to complete.
