Best Practices

Applies to CA6000 and CA6300 appliances

To minimize hardware issues:

Always shut down the Vertica metrics database before shutting down or restarting the appliance.
Ensure that the appliance is properly protected from unexpected power off conditions by implementing UPS redundancy.
Ensure that the appliance is operating within environmental specifications.
Check the RAID status for SCSI disk errors or failures at regular intervals. RAID status information is available from:
- The System Status page of the Multi-Port Monitor web interface
- The Linux system logs
If errors or failures occur:
- Recover Degraded RAID arrays as soon as possible.
- Attempt recovery from SCSI disk corruption errors.
- Replace failed drives as soon as possible to restore full system performance.
For notification of a RAID array returning to Optimal state following a rebuild, edit SNMP Traps. Change the mtpRAIDTrap severity to change the minimum severity level to Info. By default, the Multi-Port Monitor sends a SNMP trap if an array is in a Degraded state, but does not send a SNMP trap following a successful rebuild.
Note that a SNMP trap is not sent when an array has Failed Stripes because the Adaptec RAID controllers that are in the appliance do not consider this to be a Degraded state.
