Environment variables
$HORCMPROMOD
This environment variable turns protection mode ON as specified in the following table. If your
command device is set for non-protection mode, this parameter sets it to protection mode.

$HORCMPERM
This variable is used to specify the HORCM permission file name. If no file name is specified,
/etc/horcmperm.conf or /etc/horcmperm*.conf (* = instance number) is the default.
• If a HORCM permission file exists, then /etc/horcmgr executes the following command to
permit the volumes specified.
Example for UNIX systems:
cat $HORCMPERM | /HORCM/usr/bin/raidscan -find inst
Example for Windows systems:
type $HORCMPERM | x:\HORCM\etc\raidscan.exe -find inst
• If no HORCM permission file exists, then /etc/horcmgr executes a built-in command to permit
all volumes of a host. See “Without a $HORCMPERM file: Commands to run on different
operating systems” (page 172) for examples of commands run on an operating basis.
• /etc/horcmgr does not execute the built-in command if the following is defined for
$HORCMPERM. This is used to execute a system command to permit the volumes specified
from a user’s shell script.
HORCMPERM=MGRNOINST.
Determining the protection mode command device
The inquiry page is not changed for a command device with protection mode ON. Therefore,
RAID Manager provides how to find the protection mode command device. To determine the
currently used command device, use the horcctl -D command. This command shows the
protection mode command device by adding an asterisk (*) to the device file name.
Example for HP-UX systems:
# horcctl -D
Current control device = /dev/rdsk/c0t0d0*
- * indicates protection ON.
