(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:
$ show device
Device Device Error Volume Free Trans Mnt
Name Status Count Label Blocks Count Cnt
VMS4$DKB0: Online 0
VMS4$DKB100: Mounted 0 ALPHASYS 30782220 414 1

(6) -zx option for RAID Manager commands
The -zx option for RAID Manager commands uses the select() function to wait for an event from
STDIN. But the OpenVMS select() function does not support any wait events from STDIN, and
select() for terminal(STDIN) is unable to echo back the terminal input.
Therefore, the-zx option for RAID Manager commands is not supported, and is deleted from the
Help & Usage display for the -zx option.
(7) Syslog function
The OpenVMS does not support the syslog function as does UNIX. Therefore, RAID Manager does
not support the syslog function. An alternative is to use the HORCM logging file for HORCM
daemon.
(8) Startup log files
When HORCM is started, RAID Manager shares a startup log file between two processes. Due to
this sharing, CRTL does not work correctly.
As a workaround, RAID Manager has two startup log files separated by using PID.
For example, under the SYS$POSIX_ROOT:[HORCM.LOG*.CURLOG] directory:
HORCMLOG_VMS4 HORCM_VMS4_10530.LOG HORCM_VMS4_10531.LOG
(9) Option syntax and case sensitivity
VMS users are not accustomed to commands being case sensitive and using option syntax, as on
UNIX. Therefore, RAID Manager changes “case sensitivity” and “-xxx” syntax for options in order
to match the expectations of VMS users as much as possible. RAID Manager allows “/xxx” syntax
for options as well as “-xxx” option, but this is a minor option.
The followings uppercase strings are not case sensitive:
•
DG* or DK* or GK* for Logical Device Name
•
-CLI or -FCA(-FHORC) or -FBC(-FMRCF) for the pair* command options
