Using HP Serviceguard for Linux with VMware

VMware recommends switches that are compatible with 802.3ad, but ESX NIC teaming will work
with regular switches and will still support the outbound load balancing and failover. Performance
is not guaranteed if you deploy enterprise switches without link aggregation features.
Serviceguard requirement. Serviceguard requires a highly available network for
applications. Use VMware NIC teaming at the host level as described above for the networks
used by applications running in the VMware guests. Do not use NIC teaming at the guest level.
You can configure NIC teaming from the Virtual Infrastructure client or from the command prompt
of the ESX host.
Shared storage
A disk array can be seen as a centralized storage pool for servers. Data from multiple servers is
stored in dedicated areas called logical unit numbers (LUNs). To accommodate scenarios where
external physical machines must share block level data with a VM, ESX Server allows raw LUNs to be
presented to the VM by means of Raw Device Mapping (RDM). Serviceguard with VM nodes is
supported only with RDM in which the VM can be configured to use storage in nearly the same way
as physical device.
To modify the configuration of a VM, the VM must be powered down. To add a LUN to a VM in
RDM mode, the first step is to invoke the add hardware wizard and select “Hard disk” as shown in
Figure.1.
