Interface Manager card problems
In addition to the Command View TL GUI, the Interface Manager card can be managed through a
command line interface (CLI). These CLI commands can be used to diagnose problems. You can access
the CLI either through a direct RS-232 serial connection or by using Telnet over the LAN. Refer to the
HP StorageWorks Interface Manager and Command View TL user guide for instructions on using the CLI.
Table 22 describes common symptoms relating to the Interface Manager card and how to resolve them.
