Figure 6 System configuration of virtual machines supported by Device Manager
Prerequisites for virtual machines managed by Device Manager agent
The prerequisite environment differs depending on the configuration of virtual machines, as follows:
• If an HBA is allocated for each virtual machine:
Install a Device Manager agent on each virtual machine to which you want to allocate volumes.
• If an HBA is shared by multiple virtual machines:
Install a Device Manager agent on any one of the virtual machines to which you want to allocate
volumes.
• If a virtual HBA is allocated to each virtual machine (if an NPIV HBA is used):
Install a Device Manager agent on all virtual machines to which you want to allocate volumes.
In addition, if you manage virtual machines on VMware ESX 4.x or VMware ESXi 4.x, install
VMware Tools on the virtual machines to be managed.
Device Manager settings for virtual machines
Configuring Device Manager: HBA assigned to each virtual machine
Register, as a normal host, each virtual machine to which you want to assign volumes. Do not register
the virtualization server that runs in the same physical environment in Device Manager.
Assign a volume path to each virtual machine (WWN). After assigning the paths, make the virtual
machines recognize the volumes as RAW devices.
Configuring Device Manager: HBA shared by multiple virtual machines
If multiple virtual machines to which you want to assign volumes share an HBA, register only one of
the virtual machines as a normal host. In addition, do not register the virtualization server that runs
in the same physical environment in Device Manager.
