Known Problems and Workarounds

The known problems and corresponding workarounds for versions B.11.11.05.01 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 -c 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.
