Dear all, actually I installed CentOS 5.4 x86_64 on 11 new Dell R710 servers. It is required to use 5.4 to be covered by the NetApp Interoperability Matrix for use of Snapdrive. All systems spit out the error message mpt2sas0: failure at drivers/scsi/mpt2sas/mpt2sas_scsih.c:4637/_scsih_add_device()! at boot time. In dmesg the complete SCSI initialization logging appears as follows: SCSI subsystem initialized mpt2sas version 01.101.00.00 loaded scsi0 : Fusion MPT SAS Host GSI 22 sharing vector 0x5A and IRQ 22 ACPI: PCI...

...is useless for any purpose and must be hard restarted with a full power cycle - it won't even shut down. Since nothing is logged, I've had precious little information to diagnose with. After several attempts to find out what's going on, I find the following emitted to the screen: mpt2sas0: diag reset: FAILED mpt2sas0: diag reset: FAILED mpt2sas0: diag reset: FAILED end_request: I/O error, dev sda, sector 226972349 Buffer I/O error, device sda5, logical block 2719747 sd 0:0:0:0rejecting I/O to offline device sd 0:0:0:0rejecting I/O to offline device sd 0:0:0:0rejecting I/O to of...

The HBA is an HP H220. We haven?t really benchmarked individual drives ? all 12 drives are utilized in one RAID-10 array, I?m unsure how we would test individual drives without breaking the array. Trying ?hdparm -tT /dev/sda? now ? it?s been running for 25 minutes so far? Kelly On 2016-05-25, 2:12 PM, "centos-bounces at centos.org on behalf of Dennis Jacobfeuerborn"

Happy new year ! We have a SuperMicro server with a LSI MegaRAID 9260-4i controller. Since Centos 6.6 update (kernel 2.6.32-504), the controller doesn't initialize at boot. Reverting to kernel 2.6.32-431 allows server to boot fine. The server can't boot due to a bug in LSI megaraid module. Boot log ends by a lot of lines: RESET_GEN2: retry=xxx, hostdiag=a4 I tried Centos 6.6
