Suggested Action:
reason for alarm. However, if this message is frequently in the log, or the number is 2 or 3, then two
actions may be necessary:
l Attempt to decrease the load on the storage. If the storage is taking longer than 3 times the
FAILFASTTIMER (3 times 5 or 15 seconds by default) then one should consider the load that
is being placed on the storage and re-balance the load to avoid these long I/O delays. This will
not only allow LifeKeeper to check the devices frequently, but it should also help the
performance of the application using that device.
l If the load can not be reduced, then the FAILFASTTIMER can be increased from the default 5
seconds. This value should be as low as possible so slowly increase the value until the
messages no longer occur, or occur infrequently.
Note: When the FAILFASTTIMER value is modified LifeKeeper must be stopped and restarted
before the new value will take affect.
