There are additional items beyond the requirements above that should be taken into consideration before installing D3 Linux 9.0.
If you are using OpenDB and you are upgrading to D3 Linux 9.0, you must also upgrade to OpenDB 3.3. OpenDB 3.3 is available in versions that allow using 32 bit ODBC drivers or 64 bit ODBC drivers. Contact your sales representative or customer support for details on obtaining the upgrade to OpenDB 3.3.
You must obtain a new copy of any third-party product that uses assembly code (for example, Accuplot, PowerComm, Jet, and so on). Third-party products that use assembly code must be updated if you are coming from a D3 7.3 or earlier release because of the frame size change. All custom code needs to be reassembled. If you have D3 7.4 or higher installed and already reassembled the custom code, there is no need to reassemble the custom code again. However, due to interface changes, it is recommended that 3rd party assembly code be recertified on D3 9.0.
The set-time command changes the D3 time but not the Linux time.
If you have Unicode enabled to use the international character set, you must do one of the following:
Modify your coldstart process to execute !unicode_stop
Execute unicode_stop before you start the VME
|
NOTE |
By default, xcs is set to off. |
When the hard disk is greater than 8 GB, an older BIOS may not pass on accurate information to the operating system. This may limit the available space of this drive to 8 GB.
When partitioning the hard disk, be advised that D3 uses raw disk partitions to store data.
DO NOT create a file system on these partitions.
DO NOT make them mountable.
DO NOT place them in the /etc/fstab file.
Only partitions with an ID of D3 display when viewing them from the D3 Virtual Disk menu. If you create your own partitions, you must create them with an ID of D3. For more information, see the D3 Virtual Disk Menu topic in the D3 Installation Guide.
Set the hard disk up with one or more partitions with no file system created on them, available for D3.
When writing to a floppy disk (for example, if you are performing an account-save or a t-dump), you must execute either the t-det (detach the tape) or t-rew (rewind the tape) command before removing the floppy disk from the device.
|
WARNING |
The floppy device may not clear the last buffer if one of the two commands is not executed. Consequently, some of the data may not be written to the floppy disk. |
In D3 version 7.1.0, the label size for 8mm tapes was changed from 512 to 80 bytes. Tapes created on earlier releases of AP or D3 can be read using this release by setting the label to 512 bytes.
To read D3 9.0.x tapes on other platforms using an earlier release of AP or D3, the label size must be adjusted to 80 bytes.
Where n is the device number:
To change the label size to 512 bytes, enter:
|
chg-device n label=512 |
To change the label size to 80 bytes, enter:
|
chg-device n label=80 |
SMP support is based on the Linux distribution.
Since Linux printing is BSD based, lppick must be told explicitly to send to lpr. Any references from existing applications to lp should be substituted with lpr. Any references to lpstat should be substituted with lpq. Neither command takes the same arguments. Refer to the man pages for more details.
To ensure proper operation of 4mm and 8mm tape devices as well as multireel saves, see the Peripherals section in the D3 Linux System Administration Guide.
By default, the Linux console maps the value of DELETE to the BACKSPACE key, and the value of BACKSPACE to CTRL+BACKSPACE. D3 expects to see a Backspace in most cases. To correct this on the Linux console, load the supplied keyboard map to swap the definitions of Backspace and CTRL+BACKSPACE:
Log in as root and enter:
|
loadkeys /usr/lib/pick/keymap |
Perform this procedure after every Linux boot. To execute this command from user-coldstart, place an ! (exclamation mark) before the command.
BACKSPACE may seemingly fail in other environments such as under X Window System or other terminal emulators. Please refer to their documentation for instructions to redefine a key or send a BACKSPACE.
The default UNIX user statement cannot be changed to null in the Display/Modify D3 configuration menu by selecting the option and pressing the Spacebar, then ENTER as indicated in the Installation Guide.
Complete the D3 installation options.
Locate the file /usr/lib/pick/vmname.
where vmname is the name of your virtual machine. Our examples in the installation guide use pick0.
Edit the file with an editor of your choice.
Go to the user line and remove it.
When Linux is installed, the permissions are set to 660 for the 3 1/2" 1.44 floppy device /dev/fd0H1440 and 660 for the /dev/nstN, where N is the number of tape drives. Because the user pick is not a root user, the permissions are not sufficient for D3. As a result, when a D3 process attempts to write to the floppy or tape, a message displays indicating that the drive is write-protected or the system hangs. To write to the device from D3 execute the command:
For floppy
|
chmod 666 /dev/fd0H1440 |
For tape
|
chmod 666 /dev/nstN |
Starting with D3 9.0, the default compression routine employs gzip instead of compress. As such, a save on a D3 9.0 system cannot be read on a D3 7.5 system without making changes.
