Hi,
We are trying to make use of a LSI LOGICS SAS drives in a customized
Linux distribution of 2.6.12.6 kernel version. We are hitting upon an
I/O Error on trying to access the drives. Have anybody faced this
problem?
The following are the details:
kernel version =2.6.12.6
mptsasdriver =mptlinux-3.02.57
Processor =Intel(R) Xeon(TM) CPU 3.20GHz
The relevant part of dmesg output on this server-
