Hello All,
I am using ppc460ex based custom board.
using linux 2.6.30.2 kernel on this board it has ibm_newemac driver in it.
I am using this board as a iSCSI target which has RAID system behind it.
||
|| ||
||
n/w driver (ibm_newemac) || n/w layer || iSCSI Target ||
RAID
|| ||
||
The problem i am facing is when i start iometer based i/o.
I am doing i/o with following specifications.
Workload type : All in one.
no of outstanding i/o : 32.
no of worker threads : 8.
With this kind of workload n/w stucks in between. and board becomes
unresponsive.
If i try to ping to the board then ping fails with 100% packet loss.
While debugging the issue i found out that
sock->sk_state_change callback is called from the TCP layer and state of the
socket is not TCP_ESTABLISHED in the iSCSI target driver.
So i am assuming that this is a problem related to n/w driver.
Did anyone faced similar kind of issue before? Please point me in right
direction.
Thanks and Regards,
Harshal Shete.
