8-18 TS3400 Tape Library Maintenance Information

To download microcode to these devices, perform the following steps:

1. Verify that the IBM tape subsystem is powered ON and online.

2. Verify that the tape drive does not currently have a tape cartridge loaded.

3. Verify that the drive is not in use by another host.

4. Determine the current version of microcode present on the device by entering the

following command, substituting n with the actual value from the device special

file associated with the target device:

/opt/IBMtape/tapeutil -f /dev/rmt/nm -o qmc -v

5. Determine the source of the new microcode image file (that is, the host file such

as /tmp/ucode_image.file).

6. Enter the following command, substituting file with the actual path and

filename of the microcode image file, and substituting n with the actual value

from the device special file associated with the destination device:

/opt/IBMtape/tapeutil -f /dev/rmt/nm -o dmc -v -z file

Note: The microcode download procedure may also be performed by using the

menu-driven interface of the tapeutil program. To invoke the tapeutil program

in this format, enter the following command, then choose option 1 to open the

device, followed by option 4 to query the current device microcode level, and

option 7 to download new microcode.

/opt/IBMtape/tapeutil

Updating Microcode from HP-UX System using TAPEUTIL

Refer to IBM SCSI Tape Drive, Medium Changer, and Library Device Drivers: Installation

and User’s Guide for details of the tapeutil program in the HP-UX system.

You may require assistance from the customer during this process.

The tape drive supports downloading a new microcode image from the host system.

This procedure downloads microcode to the tape drive from a file or diskette. This

diskette must be in AIX/UNIX format.
