If the server has started degrading, the recovery tasks will vary depending on whether the cause was the switch (failover or switchover), or the disconnection.
Execute the mc_ctl command in status mode, or refer to the system log, and check if the cause of the server degradation was the switch or the disconnection.
In the example below, the mc_ctl command is executed in status mode.
If a switch has occurred, "switched" (the switch is complete and the server is in a degrading state) is displayed for "mirroring status".
Example)
$ mc_ctl status -M /mcdir/inst1 mirroring status ---------------- switched :
If a disconnection has occurred, "not-switchable" (disconnection was performed so the server cannot be switched) is displayed for "mirroring status".
Example)
$ mc_ctl status -M /mcdir/inst1 mirroring status ---------------- not-switchable ：
