iscsi-sfnet: Failing command cdb...

Post by risenhoover » 2008/01/14 17:57:47

Hi all,

I've been running a CentOS server connected to a Promise VTrak m500i
via open-iscsi quite successfully for over a year now. A few days ago
the performance plummeted on the drive and I'm seeing the following
messages in my log file:

Jan 14 09:06:13 flax kernel: iscsi-sfnet:host7: ping timeout of 5 secs
expired, last rx 161502341, last ping 161507
341, now 161512341

before next login attempt
Jan 14 09:06:15 flax kernel: iscsi-sfnet:host7: Session established

Here's the output from uname--a:

[root@flax fileroot]# uname -a
Linux flax.x.x. 2.6.9-55.0.9.ELsmp #1 SMP Thu Sep 27 18:27:41 EDT 2007
i686 i686 i386 GNU/Linux

Does anybody have any thoughts on what could be causing this?

Thanks,
W.
