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:

In the source code of the mpt2sas.ko module
http://www.takatan.net/lxr/source/drivers/scsi/mpt2sas/mpt2sas_scsih.c?v=2.6.18-164.el5;a=x86_64
the code part responsible for the error messages is
4633 /* check if this is end device */
4634 device_info = le32_to_cpu(sas_device_pg0.DeviceInfo);
4635 if (!(_scsih_is_end_device(device_info))) {
4636 printk(MPT2SAS_ERR_FMT "failure at %s:%d/%s()!\n",
4637 ioc->name, __FILE__, __LINE__, __func__);
4638 return 0;
4639 }
I am not sure what that should tell me. I can not detect any misfunction
once the systems are up and running, nor any further error loggings.
Any clue about the severity of that mpt2sas check and failure note?
Best regards
Alexander
