How can I be notified immediately when a drive on my Linux server fails?
You can configure RAID to notify you immediately when a there is a problem with a drive on your Linux dedicated server. How you do this depends on which RAID driver your server has.
To Determine Your Server's RAID Driver
- Connect to your Linux dedicated server using SSH.
- Use the following command: lspci
The command returns one of the following:
- Highpoint returns
07:04.0 SCSI storage controller: HighPoint Technologies, Inc. RocketRAID 1720 (2x SATA II RAID Controller) (rev 02).Note: Older Highpoint drivers return a similar value.
- IMSM (Intel Matrix Storage Manager) returns
00:1f.2 RAID bus controller: Intel Corporation 82801 SATA Controller [RAID mode] (rev 05).
Note: RAID automatically sends server notifications to our Dedicated Hosting support team. We recommend that you continue to use this configuration and simply add yourself to the notification list. Any other changes to your RAID configuration could result in a hard drive failure going undetected.
