Check the major number and minor number of HDLM raw devices
used by Oracle RAC 11g by executing the following command in each
node:
# ls -lL HDLM-raw-device-file
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.
b
.
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.
c
.
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 11g 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
#
d
.
Execute the following command for the created alias device file and
check that the major number, minor number, owner, group, and
access permission mode is properly set:
# ls -l /dev/alias-device-file
Execution example:
# ls -l /dev/crs_ocr1
crw-r----- 1 root oinstall 307, 1608 date/time /dev/crs_ocr1
