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.

NOTE: A complete DLKM infrastructure is required to enable the DLKM feature of the

driver, which requires that you install the following three kernel patches:

1. PHKL_36387

2. PHKL_36332

3. PHCO_36371

• Use Consistent OS and Software Versions in the Fabric

HP requires all systems in the fabric to use both the same HP-UX OS software version, and

the same HP-UX Fabric Clustering System for InfiniBand software version, such as version

B.11.31.0909 or B.11.31.0909.1.

HP requires all switches in the fabric to use the same firmware image version such as:

HP-374305-001-Release-2.5.0hp-build014.img

Use the latest software and switch firmware available online at: http://support.hp.com .

1. Select Software and Driver downloads.

2. Enter your product name.

3. Click the double arrow.

Refer to the section "Configuration, Image, and Log Files" in the HP Fabric Clustering System

HP-UX Administrator's Guide for details.
