HP XC System Software Release Notes for Version 4.0

In the previous example, the switch_modules table in the qsnet database is populated with
QR0N03 even though the QR0N03 module is not physically present. This problem has been
reported to Quadrics, Ltd.
To work around this problem, delete the QR0N03 entry (and any other nonexistent switch entries)
from the switch_modules table, and restart the swmlogger service:
# mysql -u root -p qsnet
mysql> delete from switch_modules where name="QR0N03";
mysql> quit
# service swm restart
In addition to the previous problem, the IP address of a switch module might be incorrectly
populated in the switch_modules table, and you might see the following message:
# qsctrl
qsctrl: failed to parse module name 172.20.66.2
.
.
.
Resolve this issue by deleting the IP address from the switch_modules table and restarting
the swmlogger service:
# mysql -u root -p qsnet
mysql> delete from switch_modules where name="172.20.66.2";
mysql> quit
# service swm restart
NOTE: You must repeat the previous procedure if you invoke the cluster_config utility
again and you choose to re-create the qsnet database during the cluster_config operation.
