Using hpacucli to disable auto logical volume disabling when failed

Using hpacucli to disable auto logical volume disabling when failed

By default, when a physical drive fails in an HP RAID array, the controller takes the logical volume offline to prevent data loss, instead of taking it in "degraded" status like LSI/Adaptec does and waiting for hot swap replacement of the failed drive and rebuild the array.

 

Is there a way to set it so it won't disable the logical volume when a single drive fails in the array and have it waiting for drive hot swap to rebuild the array by using hpacucli?

Re: Using hpacucli to disable auto logical volume disabling when failed

Are you sure the logical volume is disabled when a physical member of the volume is bad or missing?

 

I never heard of this behaviour of SmartArray Controllers in servers ranging from dl380g3 to g7 and dl360 servers.

 

What model is your server that shows such behaviour?

 

Could you post the output of

 

hpacucli ctrl all show detail

(replace sensitive data such as serial numbers etc)?

 

Default behaviour is to mark the failed drive as "Failed" and leave the logical volume active.

 

You would then remove the bad disk and insert the replacement. The RAID rebuild will start automatically.

This may be kind of true, but ONLY for RAID0!

But data is lost in that case.

 

 

The normal behaviour is to set it to degraded and rebuild it on a spare.


Hope this helps!
