RAID array consistency checks

[HDClown]

My Adaptec 5405 RAID controller supports background consistency checks. Is this something I should enable? The Adaptec Storage Manager says that if your card doesn't support background consitency checks, then you should run a manual check each week, so that leads me to believe I should enable it

Also, ASM has a verify and verify with fix option. Does anyone know if the background consistency checks do a verify with fix, or just a verify?

It's a good idea to do so. I data scrubbed my software arrays once a week before I had hardware cards and now I have scheduled verify jobs on my 3ware cards.

I'd run the verify with fix. Just schedule it to run sometime when you're not at the computer (at work, sleeping, etc).

checking raid1/5/6 for consistency once a week or so is good idea. I run a check on my raid5 every monday while im at work

My RAID5 arrays automatically get checked with repair every Monday at 0400Z.

Adaptec Storage Manager lets you schedule a Verify+Fix (Build/Verify), and you also have the option to enable consitency check with a scheduled interval on the controller itself (shortest interval being 10 days).

I'm not quite sure if there's a difference in the two. The help isn't very useful with technical details between the two.

Awesome, I didn't even know the storage manager had this option... Just scheduled my first verify/fix.
