DeviceGroup Parameters
Device groups are defined within the DeviceGroups section. This section
contains zero or more DeviceGroup sections.
The layout is as follows:
Each DeviceGroup section can have one or more devices (nodes and ports).
Devices are matched against PathRecord and Multicast SA queries so that the
returned SLID/DLID, PKey, SL, and so on are appropriate for the vFabric that
contains the device(s).
Devices in a DeviceGroup but not found in the fabric are ignored.
When security is enabled for a vFabric, further measures will be taken, using
PKeys, to secure the vFabric and ensure devices in other vFabrics cannot talk to
devices in the given vFabric. Such security includes hardware enforced
per-packet PKey checking and enforcement.
DeviceGroups not used in any vFabric will have no effect.
NOTE:
To effectively use the DeviceGroups section, the administrator must
carefully list the required devices in each DeviceGroup section. FastFabric
Toolset commands, such as iba_saquery and iba_report, can help
generate the lists.
Portions of iba_report XML output, such as iba_report -o brnodes
-x, can be cut and pasted into the appropriate DeviceGroup sections.
When assigning devices to a vFabric, the capabilities of the device must be
considered. There is a limit of the number of Secure VirtualFabrics a given
device's port can be in. That limit is dependent on the PKey capabilities of the
hardware.
The PKey capabilities of the devices shipped by QLogic are as follows:
