Functional Issues

Table 7-3 lists functional problems that may occur with using SANsurfer FC HBA

Manager, and provides possible causes and solutions.

Table 7-3. Troubleshooting: Functional Issues

Problem Cause and Solution

Unable to create failover con-

figuration.

Cause: An incorrect version of SANsurfer FC HBA Manager is installed

or SANsurfer FC HBA Manager detected an invalid configuration.

Solution: To create a failover configuration, the following criteria must

be met:

 The host system must contain two or more adapters.

 The storage subsystem must report the same device node name

and separate device port names for each port.

 The storage subsystem must report the same total number of LUNs

down each path.

 The storage subsystem must report the same LUN numbers for

each port.

Unable to create load bal-

ance configuration.

Cause: SANsurfer FC HBA Manager detected an invalid configuration.

Solution: To enable load balancing, each storage subsystem must

report multiple LUNs. When using a JBOD, you must individually con-

figure and manually balance each device.

Unable to mask LUNs. Cause: The LUN path is unconfigured.

Solution: In the Fibre Channel Configuration dialog box, set the device

path to visible (or hidden, if a failover configuration will be saved).

Unable to set device path as

visible, hidden, or unconfig-

ured.

Cause: The SANsurfer FC HBA Manager user interface or qlremote

agent did not detect any devices.

Solution: Verify that the SANsurfer FC HBA Manager user interface

shows the devices under their adapters in the

FC/CNA HBA tree. Each

device should show its device port name and its connected LUNs.

Unable to set LUN path as

preferred or alternate.

Cause: The LUN path is not configured or the devices were not

detected by the SANsurfer FC HBA Manager user interface or qlremote

agent.

Solution: Verify that the SANsurfer FC HBA Manager user interface

shows the devices under their adapters in the

FC/CNA HBA tree. Each

device should show its device port name and its connected LUNs.

Unable to get host Informa-

tion.

Cause: The qlremote agent is not running or installed.

Solution: Verify that the qlremote agent is installed and running (see

“Verifying that qlremote is Installed and Running” on page 7-12).
