Updating Microcode from Windows NT or Windows 2000 using
NTUTIL
For a complete update on device driver software, see the IBM SCSI Tape Drive,
Medium Changer, and 3592 Device Drivers: Installation and User’s Guide .
You may require assistance from the customer during this process.
The tape drive supports downloading a new microcode image from the host system
via the fibre channel. This procedure downloads microcode to the tape drive from a
file.
Note: The microcode download procedure may be performed by using the
menu-driven interface of the ntutil program. To invoke the ntutil program in
this format, go to the common start: followed by commands: option 20 to open
the device, followed by option 85 to query the current device microcode level,
and option 82 to download new microcode:
1. Verify that the IBM tape subsystem is powered ON and is online.
2. Verify that the tape drive does not have a tape cartridge loaded.
3. Start ntutil and open the drive (see Step 1 through Step 5 in “Starting NT
UTILITY (NTUTIL) from Windows NT or Windows 2000” on page 8-21). Return
here.
4. Determine the version of microcode present on the device by entering the
following command
85 (Get Version).
5. Update the microcode by entering the following command 82 (Update Code).
Ntutil will prompt you for the microcode level.
6. Enter the microcode level ( D3I0_43B , for example).
This command will call the device driver DeviceIoControl ( ) entry point, and
will load the new microcode.
7. Go to the Close routine, and complete Step 7 on page 8-23.
Updating Microcode from SP2 using TAPEUTIL
You may require information or assistance from the customer during this process.
This procedure downloads microcode to the tape drive from a file or diskette. This
diskette must be in AIX/UNIX format. The Microcode Load utility is only supported
on the tape drive.
1. Insert the CD-ROM with the microcode load in the Control Work Station (CWS)
CD-ROM drive. Ensure you select the proper EC level for the drive that is being
updated.
2. Copy the contents of the CD-ROM to a file on the CWS.
3. Copy the file to the SP2 node that has the tape drive attached.
a. Connect to the target node by typing ftp nodeid .
Enter a name and a password when prompted.
b. Set Binary mode by typing binary .
c. Transfer the file.
d. Quit the connection by typing quit .
4. At the drive service panel, verify that the drive is online.
5. Verify that the drive is unloaded.
6. Verify that the drive is not in use by another host.
