4.2.2.3. Proper System Shutdown
The BCU/CAL must be shut down in an orderly fashion prior to a system reboot. This procedure essentially
disconnects the link to the IMC CAM, gracefully closes any open files (especially significant for the BCU), and secures the
hard drive file system. The proper way to shut down the BCU/CAL can be executed from either the "root" or "admin"
accounts. This procedure is shown by way of example.
USER INFORMATION: Invoke the BCS program.
pSH+> bcs
Welcome to the BCU-CAL Configuration Service (BCS)
System Administrator privilege acknowledged.
USER INFORMATION: The BCS "halt" command performs the proper shutdown procedure.
BCS> halt
USER INFORMATION: Wait at least 2 minutes from issuing the "halt" command, then exit BCS.
BCS> exit
pSH+>
At this point, the BCU/CAL may be powered-down, or rebooted, without concern for disk data integrity. Under
extreme (i.e., panic) circumstances, the "root" user can force an immediate reboot by entering "reboot -h" at the pSH+>
prompt, either at the user console or via a telnet connection.
4.2.3. Software Upgrades
Software upgrades are similar to the initial installation procedure discussed above. Each time the BCU/CAL boots, it
will check to determine whether a floppy diskette is installed. If a diskette is present, it will be scanned to check whether
any BCU/CAL installation files are present. If applicable files are detected, they will be copied to the appropriate system
disk directory. As in the initial installation procedure, the operator will be prompted to remove the current diskette and
insert the next one.
This method also applies to customer modifications to the contents of Installation Diskette 4. Specifically, if (new)
changes are made to either the IP.DAT or CAL.DAT files, the BCU/CAL should be rebooted with the modified diskette
inserted in the floppy drive.
