HyperFabric Release Notes HP-UX 11i v1 and HP-UX 11i v2 April 2010

Known Problems and Workarounds
The known problems and corresponding workarounds for versions B.11.11.05.01, B.11.11.05.02,
and B.11.23.03.01 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 SAM, set STRMSGSZ to 0 (zero) to unset the parameter.
• The switch management software in HyperFabric has some problems that may result in the
following symptoms:
— The HyperFabric management daemon (clic_mgmtd) loses connection with other
nodes in the cluster.
— Invalid class messages (that is, class messages that are not related to HyperFabric) get
logged into the /var/adm/clic_log global log file.
WORKAROUND: Disconnect the HyperFabric switch(es) from the Ethernet network, and
leave them disconnected. Then, reconfigure HyperFabric by doing one of the following:
— Use the clic_init -pc command, but do not configure switch management.
— Use SAM (HP-UX 11.0 and 11i v1 only). As mentioned earlier, you cannot configure
switch management within SAM.
HyperFabric will work correctly without switch management configured, but the switches
will not create diagnostic logs.
• When you run the clic_probe nodename -c adapter_ID command, if the adapter
specified by adapter_ID is not operational— and another (operational) adapter is installed
in the “source” node (the node you specified the clic_probe command
from)—clic_probe uses the other adapter. However, clic_probe does not notify you
that the adapter you specified is not operational. This will be fixed in a future release.
• If you update the HyperFabric software from a version earlier than B.11.00.11 or B.11.11.01
to the current release, the following things happen:
— The files /etc/rc.config.d/clic_global_conf and /etc/rc.config.d/
netconf are moved to the directory /tmp/clic.software_version/ (for example,
/tmp/clic.B.11.00.10).
— The /etc/rc.config.d/clic_global_conf file is deleted.
The result is that HyperFabric cannot find the existing configuration information, because
it has been removed from its normal locations.
WORKAROUND: After the HyperFabric software installation is complete, you must run
clic_init -c to create the global configuration file. When you do this, consider the
following things:
— If you want to keep the existing configuration: You must re-specify the existing
configuration information when you run clic_init -c. To do this, refer to the contents
of the two files that were moved to the /tmp/clic.software_version/ directory (the existing
configuration information is stored in those two files). Then, specify that configuration
information when you run clic_init -c.
— If you do not want to keep the existing configuration (that is, you want to do a new
configuration): Run clic_init -c and specify the configuration information you
prefer.
• HP-UX 11i v1 installation issue on systems that have HyperFabric cards. Customers installing
or re-installing HP-UX 11i v1 using the Guided Installation option may encounter a program
loop during network configuration the first time the system reboots. This is not due to a
defective card.
