The path depends on the hardware architechture of your server.
Thus output from a rp7400 (N class) would be different from your superdome partitions and so on. How is your system bus and how many logical bus adapters are then finally which cards are connected to the lba's and how many ports are there on the card - or if disks/tapes are visible through the card interfave etc
The explanation provided above should give you an understanding as well.

The main reason that in your specific server you have seven digits in your h/w path is becuase probably you are using a SAN, and that last digit after the period is indicating the LUN number, which is not an entire disk, but rather a virtual partition of your raid set.

How did you add the printer? Is it an HP printer with an HP JetDirect LAN card? Or is it a non-HP printer? The spooling system has virtually no diagnostics. Even an ordinary user can use the disable command to disable a printer. Depending on the network connection, the printer may become disabled due to paper out or paper jam or just a bad network.

PSADMIN? Is this a program on your HP-UX computer or your PC? If it is on the PC and it's printing to the HP-UX computer as a print server, then PSADMIN is out of the picture. When a printer is disabled, there is no automatic way to re-enable it. Someone or some process must check and constantly re-enable the printer queue. The non-HP printer (or more accurately, the non-HP network card in the printer) has been setup as a dumb remote printer so HP-UX gets no status as to the printer's condition. So there is no way to see why the remote printer is not working.

You would need to create a script that looks at all the printer queues on HP-UX, and run the enable command on any that have become disabled. Put this script into cron and run it every 5 or 10 minutes.
