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 11g corresponding to that device. For details on this point, refer to the
Oracle documentation.
# chmod

/dev/
alias-device-file
# chown
owner
:
group
/dev/
alias-device-file
Execution example:
# chmod 640 /dev/crs_ocr1
# chown root:oinstall /dev/crs_ocr1
#
4. 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
