that OpenVMS cannot make a daemon process from the POSIX program. Therefore, horcmstart.exe
has been changed to wait until HORCM has been exiting by horcmshutdown.exe after startup of
the horcmgr. According to the rule for creating process in OpenVMS, to start up the horcmstart.exe
is to create the detached process or Batch JOB by using DCL command, as this method closely
resembles the horcmd process on UNIX.
For example, using the Detached process:
If you want to have the HORCM daemon running in the background, you need to make the
Detached LOGINOUT.EXE Process by using the ‘RUN /DETACHED’ command of the OpenVMS,
and need to make the commands file for LOGINOUT.EXE.
The following are examples of “loginhorcm*.com” file given to SYS$INPUT for LOGINOUT.EXE,
and are examples that “VMS4$DKB100:[SYS0.SYSMGR.]” was defined as SYS$POSIX_ROOT.

You can also verify that the HORCM daemon is running as Detached Process by using the show
process
command.

(5) Command device
RAID Manager uses the SCSI class driver for accessing the command device on the XP1024/XP128
Disk Array, because OpenVMS does not provide the raw I/O device such as UNIX, and defines
“DG*,DK*,GK*” as the logical name for the device. The SCSI class driver requires the following
privileges: DIAGNOSE and PHY_IO or LOG_IO (for details see the OpenVMS manual).
In RAID Manager version 01-12-03/03 or earlier, you need to define the Physical device as either
DG* or DK* or GK* by using DEFINE/SYSTEM command. For example:
