Device Designation - Itanium RX-2620

Phillip Tusa — Fri, 05 Oct 2007 09:24:18 GMT

Greetings to all ...

Does anyone know where I can get a current list
of all the device designations on an Itanium rx-2620?

Thanks in advance!

Phil

Phil,

$ SHOW DEVICE

Maybe you could be a bit less generic in your question. Do you want to know a list of possible OpenVMS device names ? Or a list of physical interfaces to be plugged into an rx 2620 ?

I believe what I am asking for is a list of device names (i.e. TTB0) and a description or summary of that device name.

Thanks

Phil

"Believe"? That's rather odd phrasing in this context.

Could you describe what you're trying to accomplish here -- in more general terms? Putting a few more words around this might help me or others better target the answer.

SHOW DEVICE/FULL will identify the (major) devices present, and will provide a short description of each. By default, you'll see the significant device.

The device driver prefixes (eg: Within TTB0: the TT is the device driver prefix, B is the second TT controller present, and 0 is the unit on the second controller) are associated with device drivers, though the drivers don't necessarily tie to specific physical devices; a particular driver can be associated with more than one physical device. The SYS$DKDRIVER and SYS$DGDRIVER (SCSI and Fibre Channel storage drivers, respectively) work with a wide variety of storage devices, for instance.

There is a list of the device driver prefixes around, though AFAIK it's not been generally published.

If you're looking for the hardware inventory or hardware configuration, mechanisms such as the ANALYZE/SYSTEM command CLUE FRU (and FRU being Field Replaceable Unit; the part or subsystem or component that traditionally gets swapped upon failure) will tell you about the major components present within the system.

I'd expect the EFI console could acquire this hardware configuration information, as well.

Correction: There is no SYS$DGdriver. DG devices are handled by DKdriver, the fibre drivers are SYS$FGEDRIVER (Emulex controller), SYS$PGQDRIVER (Qlogic controller) and SYS$PGADRIVER (fibre/scsi protocol driver, only used in combination with SYS$FGEDRIVER).
