Yes, there are few utilities that you can use.
First it is wise to analyze the logs. Maybe the malfunctioning is already showing itself in the logs.
CF is ad0 and HDD is ad1 or ad2.
You can use smartd to check the HDD/CF state. These are options that you have.
smartd -oA /dev/ad1 ………. Stops any currently running tests
smartd –oS /dev/ad1 ………. Runs short self test
smartd -oX /dev/ad1 ………. Runs extended diagnostic test. May take about 30 minutes
smartd -oa /dev/ad1 ………. Shows results of the test
It is recommended to run these commands on the backup RE. Do a switchover to run them on both REs.
