Troubleshooting Linux Issues
_____________________________________________________________________
LOGIN FAILURE WITH RHEL INITIATORS
Problem
When using RHEL's
qlogic qla2xxx
driver, the initiator may fail to log in to the target. When this
happens, disc failure messages will appear in
/var/log/messages
.
Solution
Use the
qla2xxx
module parameter on the initiator side:
modprobe qla2xxx ql2xasynclogin=0
To have this setting used automatically, create the
/etc/modprobe.d/qla2xxx.conf
file and add
the following line:
options qla2xxx ql2xmaxqdepth=2
If
qla2xxx
is loaded during boot time, then run
mkinitrd
(or
dracut –f
on RHEL 6.x)
to pick up
the changes.
ORACLE LINUX 6.3 ISSUES
Problem
When running Oracle Linux 6.3, OpenSM and srptools may encounter problems. The following error
may occur:
# srp_daemon -oaev >/dev/null
26/07/13 12:49:01 : umad_open_port failed for device mlx4_0 port 1
The reason is that neither the OpenSM package nor the
srptools
package works on an unmodified
Oracle Linux 6.3 system.
