3. Creating an HDLM Environment

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
