HyperFabric Release Notes Announcement Announcement HyperFabric is a high-speed network link that runs on various HP systems running HP-UX. HyperFabric supports Hyper Messaging Protocol (HMP) and the IP network protocol stack (TCP/IP/UDP). This release note contains information about version B.11.31.01 of the HyperFabric software. Notice of non support of Oracle 10g RAC HyperFabric product suite was designed to optimize performance of Oracle 9i RAC database running on HP-UX clusters.
HyperFabric Release Notes What’s in This Version What’s in This Version HyperFabric version B.11.31.01 supports the following features: Support for Transparent Local Failover on HMP When a HyperFabric resource (adapter, cable, switch or switch port) fails in a cluster, HMP transparently fails over traffic using other available resources. This is accomplished using card pairs, each of which is a logical entity that comprises a pair of HF2 (HyperFabric2) adapters on a HP 9000 node.
HyperFabric Release Notes What’s in This Version For example, if there is a single card-pair (i.e., 2 CLIC adapters) present in a system, you can set the following attributes to the given values: • CLIC_ATTR_APPL_MAX_PROCS 4997 • CLIC_ATTR_APPL_MAX_NQS 9994 • CLIC_ATTR_APPL_MAX_MEM_EPTS 9994 • CLIC_ATTR_APPL_MAX_RECV_EPTS 9994 System tunables for the shared memory should be modified based on the attribute values, but shared memory must be less than 4 GB.
HyperFabric Release Notes Known Problems and Workarounds Known Problems and Workarounds The known problems and corresponding workarounds for versions B.11.31.01 of the HyperFabric software are as follows: • HyperFabric initialization may fail if the STRMSGSZ kernel parameter is set. WORKAROUND: Set STRMSGSZ to 0 on /stand/system from the command line to unset the parameter. In SMH, set STRMSGSZ to 0 (zero) to unset the parameter.
HyperFabric Release Notes Known Problems and Workarounds WORKAROUND: Use the “Advanced Configuration” rather than the “Guided Installation” when installing or re-installing HP-UX 11i v3 on a system that has HyperFabric cards installed on it. • When the system is upgraded to HP-UX 11i v3 from a prior OS version, if there are HF1 cards (A4919A, A6092A) installed on the system, they will not be detected by the HyperFabric software, as these are not supported on HP-UX 11i v3.
