A Troubleshooting This appendix provides answers regarding the following: • Dynamic disk support—see page 87. • Launch-time support—see page 87. • Linux server on my local SAN is not discovered—see page 88. • Lost aliases support—see page 88. • New server support—see page 89. • OS support—see page 89. • Refresh Subsystem List support—see page 89. • Simple SAN Connection Manager does not discover my subsystems—see page 90. • Simple SAN Connection Manager does not start up—see page 90.
Why is the Linux Server on my local SAN not discovered? Symptoms: A new Linux server has been added to the SAN, and it has the appropriate Simple SAN Connection Manager Agent running, but the Linux server is not being discovered by the Windows 2003 Simple SAN Connection Manager server. Solution: If the local SAN is not running DNS, then there is no Domain Name Server to perform the name server-to-IP resolution for the newly-attached server.
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? 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 Managing the server list on page 78).
When I open Simple SAN Connection Manager, why doesn’t it discover my subsystems? Symptoms: This can be caused by several factors: • Another application is running on the same or different system and connects to the subsystem. Some storage subsystems only allow a single application to connect and perform management functions on them. • The subsystems do not have an FC link to the Simple SAN Connection Manager system.
In the Logical Disk Server Presentation dialog box, it shows “Unknown Server.” What does this mean? Symptoms: An Unknown Server may appear if: • The logical disk in the storage subsystem is assigned to an HBA, but the application cannot discover that HBA in any of the servers. • The server is offline. • The HBA is from a vendor other than HP. • You made specific changes to an HBA (for example, changing the type).

Glossary adapter See HBA (Host Bus Adapter). BIOS Basic Input Output System (typically in Flash PROM). The program (or utility) that serves as an interface between the hardware and the operating system and allows booting from the HBA at startup. device A target, typically a disk drive. Hardware such as a disk drive, tape drive, printer, or keyboard that is installed in or connected to a system. In FC, a target device.
partition A portion of a physical disk that functions as if it were a physically separate unit and is dedicated to a particular operating system or application and accessed as a single unit. path A path to a device is a combination of a HBA port instance and a target port as distinct from internal paths in the fabric network. A fabric network appears to the operating system as an opaque network between the HBA (initiator) and the target.
