Configuring the Primary and Secondary Cell Managers

The following sections explain how to configure the Primary and
Secondary Cell Managers.

NOTE

The following sections provide step-by-step examples to configure the
Primary and Secondary Cell Managers. Directory and file names,
numbers, and other variables will differ from the following examples
according to your environment.

Configuring the
Primary Cell
Manager

When configuring the Primary Cell Manager, you should first create a
volume group. If you are using ob2 disk as a cluster lock disk, you should
already have created a volume group for it. If you are not, follow the
steps:

1. Create a volume group on a shared disk accessible to both Cell

Managers (for example,

/dev/vg_ob2cm

), with the following steps:

a. Create a directory for a new volume group:

mkdir /dev/vg_ob2cm

NOTE

The shared volume group will contain the IDB and configuration files.
Keep this in mind when considering the size of the shared disk.

b. List all existing volume groups on the system to look for the next

available minor number:

ll /dev/*/group

c. Create a group file for the volume group:

mknod /dev/vg_ob2cm/group c 64 0x010000

d. Prepare the disk(s) to be used within the volume group:

pvcreate -f /dev/rdsk/c0t1d0

pvcreate -f /dev/rdsk/c1t2d0

e. Create the new volume group:

vgcreate /dev/vg_ob2cm /dev/dsk/c0t1d0 /dev/dsk/c1t2d0
