3. Creating an HDLM Environment
79
Execution example:
# ls -lL /dev/rdsk/c10t50060E8005271760d5s0
crw-r----- 1 root sys 307, 1608
date/time
/dev/
rdsk/c10t50060E8005271760d5s0
#
In this example, the major number is
307
and the minor number is
1608
.
2.
Create an alias device file by executing the following command in each
node. An alias device file corresponding to one disk slice should have the
same name in all the nodes.
# mknod /dev/
alias-device-file
c
major-number
minor-number
Note:
The name of the alias device file should not be duplicated with a device file
name created under the
/dev
directory by Solaris or other drivers.
Execution example:
# mknod /dev/crs_ocr1 c 307 1608
#
In this example, a device file for RAC whose major number is
307
and minor
number is
1608
is created.
3.
For the created alias device file, set the owner, group, and access permission
mode by using the following command. The owner, group, and access
permission mode to be set differs depending on the usage purpose of Oracle
RAC 10g corresponding to that device. For details on this point, refer to the
Oracle documentation.
# chmod
mode
/dev/
alias-device-file
# chown
owner
:
group
/dev/
alias-device-file
Execution example:
# chmod 640 /dev/crs_ocr1
# chown root:oinstall /dev/crs_ocr1
#
