Q
Unable to create load
balance configuration
Cause: SANblade Manager detected an invalid configuration.
Solution: In order to enable load balancing, each storage
subsystem must report multiple LUNs. If a JBOD (just a bunch
of disks) is used, each device must be individually configured
and manually balanced.
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 unconfigured
Cause: The SANblade Manager GUI or qlremote agent did not
detect any devices.
Solution: Verify that the SANblade Manager GUI displays the
devices under their adapters in the HBA tree. Each device should
display 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 SANblade Manager GUI or qlremote agent.
Solution: Verify that the SANblade Manager GUI displays the
devices under their adapters in the HBA tree. Each device should
display its Device Port Name and its connected LUNs.
Unable to get host
Information
Cause: The qlremote agent is not running or installed.
Solution: Verify that the qlremote agent is installed and running:
■ For Windows NT/2000, open the Services window and verify
that the QLogic Management Suite Java agent service is
running.
■ For NetWare, at the server command prompt type the
following and then press ENTER. Verify that qlremote.nlm is
loaded.
modules q*
■ For Red Hat Linux, type the following command and then
press ENTER. If entries display, qlremote is running.
ps ax | grep qlremote
■ For Solaris SPARC, type the following command and then
press ENTER. If entries display, qlremote is running.
ps -e | grep qlremote
Unable to display the
Host Statistics tabbed
page
Cause: QLdirect is not installed.

QLdirect driver is installed. This option is available only for
Windows NT/2000.
