HyperFabric Release Notes
Known Problems and Workarounds
Known Problems and Workarounds
The known problems and their workarounds in this version of HyperFabric 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.
•
The switch management software in HyperFabric may exhibit the following symptoms:
— The HyperFabric management daemon (clic_mgmtd) loses connection with other
nodes in the cluster.
— Invalid class messages, class messages that are not related to HyperFabric are logged
into the /var/adm/clic_log global log file.
Workaround: Disconnect the HyperFabric switch or switches from the Ethernet
network, and leave them disconnected. Then, reconfigure HyperFabric by using the
clic_init -c command or SAM, but do not configure switch management.
HyperFabric works correctly without the switch management configured; but the switches
do 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.
•
Some of the directory structures of the Hyperfabric software remains on the system even
after removing the Hyperfabric software (for example, /opt/clic). This will be fixed in a
future release.
