Hello, Mike Thank you for help me a lot. The timeout is 30. # cat /sys/block/sdb/device/timeout 30 I'm afraid that problem is the storage self. So I called the HP customer service for asking the normal performace of the storage. The HP customer service show me that.

Open-iscsi with bnx2i driver, current status ?

2010-05-21 Thread MrJacK
Hi all, With the latest release of open-iscsi, is there a way to use the offload capabilities of Broadcom cards like NetXtreme II BCM5709 (bnx2i driver) ? For me, the only result i get on a 2.6.32 kernel for example is the following : kernel: bnx2i [01:00.01]: ISCSI_INIT passed kernel: bnx2i

We have a SLES 11 server connected to an Equallogic 10 Gig disk array. Initially everything seemed to work just fine. When doing some IO testing against the mounted volumes, in which we cause very high IO loads, i.e. 95 to 100% as reported by iostat, we started seeing the following messages in

Mike, thanks for the reply. The first line in the log i posted shows the ping timeout. Or were you wanting to see something else? Let me know what specifically you are looking for. Yes we are using multipath, I can post multipath.conf if that helps. I tried tweaking various settings in
