Re: Console connection to Model 10 Problems
After you got nada, try to press ctrl+L or ctrl+^ to redraw the screen.
Please,
see one of the subjects, "Clarion 9137" in disk array forum where you may find any help.

Re: Console connection to Model 10 Problems
Do you get the same response from both Storage Processors (SP)? If so, I would look at the possibility of a bad serial cable or terminal misconfiguration. It's possible to have two bad SP's but not likely that both have bad serial ports.
Just to be sure that the terminal is communicating using your cable, configure the terminal emulation for EM100 mode, and setup the comminication parameters of PORT1 (Datacomm) on the terminal to 9600, No Parity and 8 data bits. Save that configuration. Also, make sure the asterisks appears in the f4 box on the screen (remote mode). Connect the cable to the terminal on Port1 but do not connect it to the disk array yet. Using a small, stretched-out paper clip, connect pins 2 & 3 together at the free end of the cable. This will not damage the terminal in any way. If the terminal and cable are well, you should be able to type keys on the keyboard and see them echo on the screen. When you remove the paper clip, the echoing will cease. If this works, you are successfully looping back keystrokes through the cable. Now you are sure that the terminal and cable are ready to go.
Now, connect it to the disk array. Try both SP's (if you have both of them). One or the other should give you something. Hit
As a last resort, and if the disk array is not in production yet, shutdown the host that is connected to the array and power the array OFF. With the known-working terminal/cable combination connected to the SP of your choice, power ON the disk array. Part of the power-on selftest for the array is to echo alpha characters to the screen (which represent the selftest currently running). This might help you determine if the transmit or receive end of the SP is not working correctly.
I have seen SP's perform all array functions correctly, but that have blown out serial ports. As a workaround, some functions can be performed through SAM (on HP-UX) to configure the array.
Good Luck.
