Switching to the Recovery Cluster in Case of
Disaster
It is vital the administrator verify that recovery is needed after receiving
a cluster alert or alarm. Network failures may produce false alarms.
After validating a failure, start the recovery process using the
cmrecovercl [-f] command. Note the following:
• During an alert, the cmrecovercl will not start the recovery packages
unless the -f option is used.
• During an alarm, the cmrecovercl will start the recovery packages
without the -f option.
• When there is neither an alert nor an alarm condition, cmrecovercl
cannot start the recovery packages on the recovery cluster. This
condition applies not only when no alert or alarm was issued, but
also applies to the situation where there was an alert or alarm, but
the primary cluster recovered and its current status is Up.
