README: 36GB 4mm Tape Drive Microcode

This package is being provided to allow the update of older IBM 36GB 4mm Tape Drives to the current level of microcode that is currently shipping from IBM.

Customers are responsible to install the latest microcode level themselves. The microcode and instructions are available at the IBM external web site:
http://www-933.ibm.com/support/fixcentral/

Microcode Download Information

In order to complete the microcode download to a 36GB 4mm tape drive you will need use AIX 5.1 diagnostics, or higher, or the Genucode program. The Genucode package is available from the IBM WEB site:
http://www14.software.ibm.com/webapp/set2/firmware/gjsn
For both the AIX diagnostic package and for the genucode package from the WEB you will need the microcode and dsdata files in this package.

This package, the 36GB 4mm package, will get you to step where you will need to use AIX diagnostics or Genucode to download the microcode into the tape drive.

Note: The BS11 level of microcode supports the new Serial Attached SCSI(SAS) DAT72 tape drive. The BS11 level of microcode is included as a reference only as this General Availability level of this drives microcode and there is no need to update a DAT72 SAS drive with this microcode as this level is already in the drive.

Operating System levels supported:

All levels of AIX that this product was announced on.

Can microcode be installed Concurrently?

Yes, but the tape drive must be available with no tape in the drive, and no other processing running to the tape drive.

Is system reboot needed to activate the microcode.

A reboot is not needed as the microcode is active in the drive when the drive completes microcode download.
If the microcode install is done with Genucode the tape drive Vital Product Data(VPD) will not show the new microcode level until you use the AIX rmdev and mkdev commands to remove and add back the tape drive.
Diagnostics does the rmdev and mkdev for you so you do not need to do the commands.

The typical time to install this microcode is .4 hrs.
The microcode becomes active when installed and does not require a system reboot to become active.

Additional Cautions:

Note:

Do not power off the tape drive during microcode download as this may damage the tape drive microcode requiring the tape drive to be replaced.

Remove any tape cartridge from the drive prior to attempting the microcode download.

Machines Affected:

All eServer pSeries and RS/6000 machines this product was announce on. In general if the tape drive configures and is available with the VPD showing the Machine Type and microcode level as described in this README the machine is one affected.

Microcode Levels

There are now three different microcode files for the DAT72 tape drive:

Two different, but equivalent levels of the DAT72 Low Voltage Differential(LVD) SCSI tape drive. There is the level that uses V315 level of microcode. This is the original drive. The new RoHS compliant level that uses the B016 level of the microcode. The drives look similar but internally they are different, that is why there are two different microcode files for the of the DAT72 LVD drive. There are different P/Ns for the different LVD drives. levels of the drive.
The new DAT72 Serial Attached SCSI(SAS) tape drive introduced in late 2007. This drive uses the BS11 level of microcode. This is feature code 5907.

Display Microcode Level

Note: In some cases you may already have the most current level of microcode already installed. The following instructions show you how to check the tape drive microcode level.

To display the level of microcode in the tape drive do the following AIX command:

 lscfg -vl rmt0               <--- change the drive number to reflect
                                   the actual rmt address of the 36GB
                                   4mm tape drive.

The output of the lscfg command will look like the following with the "Device Specific.(Z1)" showing the microcode level:

Putting the microcode on the system

There are 2 ways a user can get the microcode files. Each of these will put the microcode on the user's system but the user may have to move the files to appropriate directory for system use.

From the IBM WEB site via the user downloading the files.

When the user downloads the microcode files from the IBM web site the user will put the packaged microcode files in to the /tmp directory.

If the user downloads the 36GB4mm.bin file the user will put the downloaded file into the /tmp directory and then use the instructions in the section of this README titled "AIX bin file".
If the user downloads the Tape4mm36GB-V315B016BS11-01.rpm file the user will put the downloaded file into the /tmp directory and then use the instructions in the section of this README titled "RPM file".

From a CD-ROM.

If the CD-ROM process is used to put the 36GB4mm.bin file on the user system the microcode files will expanded into the /tmp/36GB4mm_web directory. The next step is to follow the instructions in this README titled "AIX bin file" and copy the files to the appropriate directory. The building and putting of the files into the /tmp/36GB4mm_web directory was done by the user when they used the CD-ROM build instructions. Tape4mm36GB-V315B016BS11-01.rpm file.
If the CD-ROM RPM process is used to put the Tape4mm36GB-V315B016BS11-01.rpm file on the user system the microcode files will be in the tmp/microcode/RPM directory. To put the microcode in the appropriate directory for the system the user executes the following AIX commands:
cd /tmp/microcode/RPM
rpm -ihv --ignoreos Tape4mm36GB-V315B016BS11-01.rpm
This puts the following files in the /etc/microcode directory for system use:

DDS_Gen5.A170029F.V315
DDS_Gen5.A170029F.dsdata
DDS_Gen5.A1700D59.V315
DDS_Gen5.A1700D59.dsdata
DDS_Gen5.A1700D61.B016
DDS_Gen5.A1700D61.dsdata
DDS_Gen5.A1700D62.B016
DDS_Gen5.A1700D62.dsdata
DDS_Gen5.A1700D65.BS11
DDS_Gen5.A1700D65.dsdata
The next step is to follow the instructions in this README titled "Verifying the Microcode".

Note: AIX commands and file names are case sensitive.
If the users AIX permission does not allow the copy to the above stated directory or file then the user will be prompted for a new location.

Packaged Microcode Files

AIX bin file

Download the 36GB4mm.bin file to the eServer pSeries or RS/6000 to the /tmp directory.
Do the following AIX commands to make the file executable:
cd /tmp
chmod +x 36GB4mm.bin
To expand the 36GB4mm.bin file use the following command:
./36GB4mm.bin
Note: The ./ before the command insures AIX paths thru the current directory to find the command.
This with put the following files in the /tmp/36GB4mm_web directory:

RPM file

Download the Tape4mm36GB-V315B016BS11-01.rpm file to the eServer pSeries or RS/6000 to the /tmp directory.
To expand the Tape4mm36GB-V315B016BS11-01.rpm file use the following commands:
cd /tmp
rpm -ihv --ignoreos Tape4mm36GB-V315B016BS11-01.rpm
You will have the following files in the /etc/microcode directory:

DDS_Gen5.A170029F.V315
DDS_Gen5.A170029F.dsdata
DDS_Gen5.A1700D59.V315
DDS_Gen5.A1700D59.dsdata
DDS_Gen5.A1700D61.B016
DDS_Gen5.A1700D61.dsdata
DDS_Gen5.A1700D62.B016
DDS_Gen5.A1700D62.dsdata
DDS_Gen5.A1700D65.BS11
DDS_Gen5.A1700D65.dsdata

Verifying the Microcode

Change to the directory where the microcode was just placed.
cd /tmp/36GB4mm_web
or
cd /etc/microcode

To insure the file was downloaded without error use the AIX command sum to get the checksum of the microcode file:
sum DDS*

Compare the sum you got with the sum of the file here, if they do not match recheck your steps in creating the file on the system:

09240   331 DDS_Gen5.A170029F.V315
51855     2 DDS_Gen5.A170029F.dsdata

Which Microcode file to Use?

You downloaded "RPM" files

If you downloaded the RPM file to the system and expanded it AIX diagnostics will use the appropriate file for updating the drive. Go to the step in this documentation
"How to Use AIX 5.1 Diagnostics Microcode Download".

You downloaded the AIX zip file

If you downloaded the zip file you will need to determine which microcode file to use and copy the file with the appropriate name to the appropriate directory.

You need to determine how you are going to download the microcode:

AIX 5.1 diagnostics(or higher).
or
Genucode.

AIX diagnostics and Genucode use different naming conventions for the microcode and dsdata file.

AIX diagnostics requires the microcode file and the dsdata file to be in the /etc/microcode directory.
Genucode requires the microcode file and the dsdata file to be in the /tmp directory.

Once you have determined which program you are going to use, AIX diagnostics or Genucode, you will need to copy the appropriate files from the /tmp directory to the appropriate directory:

Copy files for AIX diagnostics

cd /tmp/36GB4mm_web
 
cp DDS_Gen5.A170029F.V315   /etc/microcode/DDS_Gen5.A170029F.V315
 
cp DDS_Gen5.A170029F.dsdata /etc/microcode/DDS_Gen5.A170029F.dsdata
 
cp DDS_Gen5.A1700D59.V315   /etc/microcode/DDS_Gen5.A1700D59.V315
 
cp DDS_Gen5.A1700D59.dsdata /etc/microcode/DDS_Gen5.A1700D59.dsdata
 
or
 
cp DDS_Gen5.A1700D61.B016   /etc/microcode/DDS_Gen5.A1700D61.B016
 
cp DDS_Gen5.A1700D61.dsdata /etc/microcode/DDS_Gen5.A1700D61.dsdata
 
cp DDS_Gen5.A1700D62.B016   /etc/microcode/DDS_Gen5.A1700D62.B016
 
cp DDS_Gen5.A1700D62.dsdata /etc/microcode/DDS_Gen5.A1700D62.dsdata
 
or
 
cp DDS_Gen5.A1700D65.BS11   /etc/microcode/DDS_Gen5.A1700D65.BS11
 
cp DDS_Gen5.A1700D65.dsdata /etc/microcode/DDS_Gen5.A1700D65.dsdata

Run AIX Diagnostics

For instructions on using the AIX Diagnostics microcode download capability refer to the section of this document titled "How to Use AIX 5.1 Diagnostics Microcode Download".

Copy files for Genucode

Genucode uses a file /tmp/dsdata to control microcode update in the tape drives. The /tmp/dsdata file is unique based on the Load ID of the tape drive. Depending on the Load ID you will need to copy different files.
To determine the Load ID of the tape drive refer to the Display Microcode Level section of this document. The Load ID of the drive is the
Device Specific.(LI)........A1700D62 . In this example its the A1700D62
Depending on the Load ID of your drive you will need to copy the files with the corresponding Load ID to the /tmp directory.

cd /tmp/36GB4mm_web
 
cp DDS_Gen5.A170029F.V315   /tmp/DDS_Gen5.V315.A170029F
 
cp DDS_Gen5.A170029F.dsdata /tmp/dsdata
 
or
 
cp DDS_Gen5.A1700D59.V315   /tmp/DDS_Gen5.V315.A1700D59
 
cp DDS_Gen5.A1700D59.dsdata /tmp/dsdata
 
or
 
cp DDS_Gen5.A1700D61.B016   /tmp/DDS_Gen5.B016.A1700D61
 
cp DDS_Gen5.A1700D61.dsdata /tmp/dsdata
 
or
 
cp DDS_Gen5.A1700D62.B016   /tmp/DDS_Gen5.B016.A1700D62
 
cp DDS_Gen5.A1700D62.dsdata /tmp/dsdata

Run Genucode

You now need to use the instructions in the Genucode package to complete the install of the microcode.
Once you have completed the instructions in the genucode package the drive will be at the current microcode level and the microcode update is complete.

How to Use AIX 5.1 Diagnostics Microcode Download

There are 2 ways to do the microcode download using the AIX diagnostics.

Using the AIX Diagnostics menu
Using the AIX Diagnostics via command line input.

Using the AIX Diagnostics menu

To use the AIX 5.1 diagnostics menu for microcode download do the following:
diag (enter)
Task Selection (enter)
Download Microcode (enter)

Select the drive you wish to download microcode to and follow the system instructions.

Note: When the system asks where the microcode file is to be found select /etc/microcode, not diskette.

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:

Note: If the previous level of microcode is not in the /etc/microcode directory you will need to use the -f option(force) as the diagnostics expect the previous level to be present in the /etc/microcode directory.
diag -c -d rmt0 -T "download" (enter)

or

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