HP StorageWorks Simple SAN Connection Manager User Guide 135

I brought a new server online and connected it to both the SAN and LAN, but Simple SAN Connection

Manager does not see it. Why not?

Is all of the functionality provided in Simple SAN Connection Manager supported on all the OSs on which

the application runs?

I tried to perform a Refresh Subsystem List and the application seems to have stopped.

Symptoms:

If Simple SAN Connection Manager has already been launched prior to a new server

being turned on and connected to the LAN and SAN, Simple SAN Connection

Manager does not automatically see this server.

Solution:

Possible solutions include:

Click Refresh the Server List (see

“Refreshing the server list,”

page 99).

Re-launch the application for the new server to appear. (This also applies to a server

taken offline.)

Ensure that QLRemote is running:
• In Windows: From Administrative Tools, Services, check to make sure the service

named “QLManagementAgentJava” is started and running. Or, in Task

Manager, check for

QLremote.exe

.

• In Linux: Enter

/etc/init.d/qlremote status

. The system should show

QLRemote as running.

Symptoms:

Some Simple SAN Connection Manager options are only supported on specific

operating systems.

Solution:

The following options are supported on the various OSs.

Linux host with QLRemote:
• Discover the host and its HBAs
• Assign LUN to the host and its HBAs
• Update HBA BIOS

Windows host with Simple SAN Connection Manager/QLRemote:
• Discover the host and its HBAs
• Assign LUN to the host and its HBAs
• Update HBA BIOS and drivers

Symptoms:

When you click Refresh the Storage Subsystem List (see

“Refreshing the storage

subsystem list,”

page 115), the system experiences an FC disruption to the

storage subsystem. This may result in Simple SAN Connection Manager being

in a “hung” state and not able to recover. If the FC connection is re-established,

the application should be able to communicate with the storage subsystem

again. However, some hardware providers may not be able to recover, causing

the application to exit and no longer able to discover the subsystem.

Solution:

To resolve this issue, make sure that the FC connection is back to normal, and

then try to restart the Virtual Disk Services service through either Computer

Management’s Service (

services.msc

command) or Command Line.
