HP Serviceguard for Linux Version A.11.20.00 Deployment Guide, August 2012

Execute the following commands to create a logical volume for the ws package:

pvcreate -f /dev/mapper/mpath1p1

vgcreate /dev/vgws /dev/mapper/mpath1p1

lvcreate -L 180M -n lvol1 vgws

mke2fs -j /dev/vgws/lvol1

mkdir /ws

vgchange -a n vgws

NOTE: The size specified in the lvcreate command, specified by the “-L” option, is related to the size

of the physical partition created on the storage device.

Backup the Volume Groups

The steps in this section should be performed on the same server where the partitions and volumes

were created.

Execute the vgcfgbackup command to backup the volume groups, for example:

vgcfgbackup /dev/vgws

Import and Configure the Volume Groups on the Second Server

At this point, you need to import the volume groups and create the mount

points on the second server.

NOTE: The Serviceguard for Linux documentation suggests using vgexport and vgimport to achieve

the same result, but vgscan on the second server is sufficient.

The steps in this section must be performed on the second server.

1. First, run the “fdisk –l” command to verify that the external devices are visible on the second

server. For example, look for /dev/sda through /dev/sdf, and /dev/mapper/mpath0p1,

/dev/mapper/mpath1p1

fdisk –l

NOTE: If you do not see these devices, test the connections and reboot the server.

2. Import the volume groups by running the vgscan command.

vgscan

Reading all physical volumes. This may take a while.

Found volume group "vgws" using metadata type lvm2

NOTE: If the volume groups are not found, reboot the server.

3. Create the mount points

mkdir /ws

4. Backup the volume group configurations

vgcfgbackup /dev/vgws

5. Deactivate the volume groups on this server

vgchange –a n vgws

Network Configuration

Configure Network Bonding

In this step, you will configure a bonded network interface. You will need to determine which

interfaces are participating in the bond. In the following example, eth2 and eth3 are configured to

create the bond0 logical interface to meet the minimum requirements for Serviceguard for Linux.
