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.11.31.1203.

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.

• Infiniband adapter firmware is not being automatically updated during boot.

The driver provides the default firmware which is packaged along with the driver module. If

the card has a lower version of the firmware than the driver packaged firmware, the following

message appears in the dmesg:

HP-InfiniBand:/ux/core/isu/IBand/kern/src/common/ib_tvr/ib_tvr_drv.c:

42757: 0/0/0/6/0/0/0: ib_t: Firmware version on the HCA is old.

Please use 'itutil' to upgrade it to the 2.9.0 version of the

firmware.

In this case, to update the driver packaged firmware on the adapter, use the command itutil

-d trace interface_name sigpot_id.

For example: itutil -d trace ib0 1

If the card firmware needs to be explicitly updated to a newer firmware version file , use this

command: itutil -d file *.bin interface_name sigpot_id
