6. To create a directory for the volume group in the /dev directory, enter a command
similar to the following, where vg_name is the name that you want to use for the
volume group:
# mkdir /dev/vg_name
7. To identify used device minor numbers, enter the following command on each
node of the cluster:
# ls -la /dev/*/group
This command displays information about the device numbers used by all
configured volume groups, similar to the following:
crw-r----- 1 root sys 64 0x000000 Mar 4 2002 /dev/vg00/group
crw-r--r-- 1 root sys 64 0x010000 Mar 4 2002 /dev/vg01/group
In this example, 64 is the major number used by all volume group devices and
0x000000 and 0x010000 are the minor numbers used by volume groups vg00 and
vg01 respectively. Minor numbers have the format 0xnn0000, where nn is a
number in the range 00 to the value of the maxvgs kernel parameter minus 1. The
default value for the maxvgs parameter is 10, so the default range is 00 to 09.
8. Identify an appropriate minor number that is unused on all nodes in the cluster.
9. To create the volume group and activate it, enter commands similar to the
following:
# /sbin/mknod /dev/vg_name/group c 64 0xnn0000
# /sbin/vgcreate /dev/vg_name /dev/rdsk/cxtydz . . .
# /sbin/vgchange -a y vg_name
In this example:
■ vg_name is the name that you want to give to the volume group
■ 0xnn0000 is a minor number that is unused on all nodes in the cluster
■ /dev/rdsk/cxtydz... is a list of one or more raw device names for the disks
that you want to add to the volume group
4.4.4.2 Create Raw Logical Volumes in the New Volume Group
To create the required raw logical volumes in the new volume group:
1. Choose a name for the database that you want to create.
The name that you choose must start with a letter and have no more than four
characters, for example, orcl.
2. Identify the logical volumes that you must create.
Table 4–5 lists the number and size of the logical volumes that you must create for
Oracle Clusterware files.
