Booting from [SYSF] During an Upgrade
C.1 Booting Procedures
C.1.3 VAX 8820, 8830, and 8840 Computers
To boot from [SYSF], use the following procedure:
1. Enter the following command at the PS-OS-0> prompt and press Return:
PS-OS-0> HALT/CPU=ALL
2. Enter the BOOT command at the PS-CIO-0> prompt in the following format:
PS-CIO-0> B dddn /R5=F0000000
Substitute BCI or BDA for ddd. Substitute the unit number of the drive
holding the system disk for n.
C.1.4 VAX 8200, 8250, 8300, and 8350 Computers
To boot from [SYSF], create a command procedure named SYFBOO.CMD before
the upgrade is started.
To create SYFBOO.CMD, use the following procedure:
Note
This procedure assumes that you have installed and booted the OpenVMS
VAX operating system and are logged in to the SYSTEM account.
1. Log in to the SYSTEM account.
2. Make sure that the console media is in the console drive.
3. To connect the console drive to the system, enter the following commands and
press Return after each one:
$ RUN SYS$SYSTEM:SYSGEN
SYSGEN> CONNECT CONSOLE
SYSGEN> EXIT
4. Use the Exchange utility to copy the appropriate boot command procedure
from the console media to your current directory on the system disk. If the
system disk is on an HSC drive and you have created DEFBOO.CMD, enter
the following command and press Return:
$ EXCHANGE COPY CSA1:DEFBOO.CMD *
5. Edit the boot command procedure. Change the line that deposits a value
in register 5 (R5). This line contains the comment !software boot flags. The
value is a hexadecimal number with eight digits. For example:
D/G R5 0 !software boot flags
Change the left-most digit of the value to reflect the name of the root
directory from which you want to boot. For example, to boot from the [SYSF]
root directory, change the line as follows:
D/G/L R5 F0000000 !designated root is SYSF
6. Rename the boot command procedure to SYFBOO.CMD. For example, if the
boot command procedure is DEFBOO.CMD, enter the following command and
press Return:
$ RENAME DEFBOO.CMD SYFBOO.CMD
