use.
a. Change directory to the /dev/rdsk directory.
b. Enter the following command to list the raw disk device names and their
associated major and minor numbers:
# ls -la
The output from this command is similar to the following for each disk device:
crw-r--r-- 1 bin sys 188 0x032000 Nov 4 2003 c3t2d0
In this example, 188 is the device major number and 0x32000 is the device
minor number.
c. Enter the following command to create a new device file for the disk that you
want to use, specifying the same major and minor number as the existing
device file:
Note: Oracle recommends that you use the alternative device file
names shown in the previous table.
# mknod ora_ocr_raw_256m c 188 0x032000
d. Repeat these steps on each node, specifying the correct major and minor
numbers for the new device files on each node.
7. Enter commands similar to the following on every node to change the owner,
group, and permissions on the character raw device file for each disk device that
you want to use:
Note: If you are using a multi-pathing disk driver with Automatic
Storage Management, then ensure that you set the permissions only
on the correct logical device name for the disk.
If you created an alternative device file for the device, then set the
permissions on that device file.
