Managing HP Serviceguard A.11.20.00 for Linux, June 2012

Messages
The coordinator node in Serviceguard sometimes sends a request to the quorum server to set the
lock state. (This is different from a request to obtain the lock in tie-breaking.) If the quorum server’s
connection to one of the cluster nodes has not completed, the request to set may fail with a two-line
message like the following in the quorum server’s log file:
Oct 008 16:10:05:0: There is no connection to the applicant
2 for lock /sg/lockTest1
Oct 08 16:10:05:0:Request for lock /sg/lockTest1 from
applicant 1 failed: not connected to all applicants.
This condition can be ignored. The request will be retried a few seconds later and will succeed.
The following message is logged:
Oct 008 16:10:06:0: Request for lock /sg/lockTest1
succeeded. New lock owners: 1,2.
Lock LUN Messages
If the lock LUN device fails, the following message will be entered in the syslog file:
Oct 008 16:10:05:0: WARNING: Cluster lock lun /dev/sdc1 has failed.
