We've seen the same in Dell R410's throwing out one or two disks from
the array under heavy load with this raidcard.

What RAID controller / driver is this, please?

By "what controller" I don't mean "SAS6i/R" - I can read that ;) - but what 
original manufacturer?
LSI? Adaptec? or???

Thanks,

SAS6i/R issues on CentOS5 ?

[Jeroen Wunnink]

Hello,

Recently we switched over to Dell R210's with SAS6i/R cards. We have 
these configured with 2x SATA disks on RAID-1
But we're running into issues where arrays are throwing out disks under 
heavy load in CentOS5 or both disks as we found on a crashed server this 
morning which was brand new installed yesterday.

We've seen the same in Dell R410's throwing out one or two disks from 
the array under heavy load with this raidcard.

In OpenManage we noticed an older driver warning which we solved by 
installing the kmod-mptfusion from elrepo.org, but we're still not sure 
if this will solve the problem and if it's even related.

Has anyone else noticed issues like these ?
