ibdatacounters
ibclearcounters

Known problems and limitations
This section provides a list of known problems and limitations as known to HP at time of publication.
If workarounds are available, they are included.
• Installation of IB4X-00 requires reboot
The IB4X-00 product bundle has four components:
1. IB subsystem (IB RDMA)
2. IPoIB
3. IB device driver (ib_t)
4. RDS driver
The ib_t driver is dynamically loadable via the DLKM, but the IB4X-00 bundle as a whole
requires a reboot on install, due to the presence of other static drivers in the bundle.
