Unix tip: Monitor disk arrays with sccli commands
Disk arrays take a lot of worry about disk failure off your shoulders, but that's no reason not to notice when one goes bad. The sccli command can tell you a lot about what's happening with your StorEdge arrays. Let it warn you about disks gone bad.
Preventing RAID problems
Using RAID storage is supposed to help anticipate such catastrophes by providing a level of fault tolerance for your storage subsystem. But even RAID can have
its problems, especially when you use some newer high-capacity hard drives in
the near-terabyte range that have less than stellar reputations for reliability.
A colleague found this out recently when one of the drives in his RAID 6 array
failed after only a year of use. Since RAID 6 provides an extra level of redundancy
over RAID 5 and can survive the loss of two drives without data loss, my colleague
felt it was safe to contact the manufacturer and request a replacement drive
for the one that failed.
