Troubleshooting Linux Issues

_____________________________________________________________________

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.
