3. Use the DM Multipath device to create the logical volumes that are used by Serviceguard for

Linux.

Please refer the HP ServiceGuard Compatibility matrix for the supported Operating Systems and the

Arrays.

NOTE:

DM Multipath devices can be used with HP Serviceguard A.11.18 for Linux . The LVM volume groups

must be configured on the DM Multipath devices. In HP Service Guard package configuration, the

disk monitor must be configured using the DM Multipath device in the format /dev/dm-x. Please

ensure that the device names (/dev/dm-x) are same across all the nodes. Configuration requirements

HP Serviceguard for Linux are available in the certification matrix available at the following website:

Configuring SteelEye LifeKeeper with DM Multipath devices

DM Multipath devices in the clustered environment can be used for file systems having Lifekeeper as

the clustering solution. To configure DM Multipath devices, complete the following steps:

1. Configure the SAN such that each host has multiple paths to the array. Present the LUN’s to all

the hosts.

2. Any file systems on the LUN’s must be mounted using the DM Multipath device.

3. See Configure DM Multipath for configuring the LUN’s for DM Multipath

4. Install and start the LifeKeeper for Linux with DM Multipath Recovery kit installed on all the hosts.

5. Create a Resource Hierarchy on LifeKeeper using the DM Multipath device.

Please refer to SteelEye LifeKeeper documentation for the supported Operating Systems and the Arrays.
