Using Older Microcode Packages

To use AIX 5.1 diagnostics with tape drive microcode packages that have not been updated yet you can copy the files using

the new naming conventions to the /etc/microcode directory and use AIX 5.1 to download the microcode to the tape drives.

The following is a sample of how to use the older files with AIX 5.1 diagnostics:

z This example uses DLT8000 microcode in the /tmp directory but the same principles apply the other "SCSD" drives:

z Download and the microcode to the /tmp directory

z The /tmp directory contains:

/tmp/DLT8000.0250.A17002A3

/tmp/DLT8000.0250.A17002A3.dsdata

/tmp/dsdata

z Copy and rename the files to the /etc/microcode directory:

cp /tmp/DLT8000.0250.A17002A3 /etc/microcode/DLT8000.A17002A3. 0250

cp /tmp/DLT8000.0250.A17002A3.dsdata /etc/microcode/DLT8000. A17002A3.dsdata

Note: The naming convention for the files in the /etc/microcode is:

MachineTypeModel.DeviceSpecific(LI).MicroCodeLevel

MachineTypeModel.DeviceSpecific(LI).dsdata

The lscfg -vl rmt0 will show the drives information such as:

rmt1 1P-19-00-5,0 Differential SCSI DLT Tape

Using AIX diagnostics

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

z Using the AIX Diagnostics menu

z 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)

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.
