SCSI cards with 11.23 on an N4000?

[Paul Condren]

Afternoon all.

Ive got a dusty olde N4000-55 which has been rebuilt to 11.23 from DVD media. The SCSI cards on the PCI bus are showing as UNCLAIMED in the ioscan and I cant see whats attached to them. They are the older wide connection type rather than the new small one.

Any ideas? Ive slapped aload of patches and hardware enablement stuff on but still no joy. The NEXUS PCI interface is claimed, its the 3 cards that are not.

This is a major pain as I cant 'see' the SCSI attached tape library etc.

thanks

Shalom,

Could be a bad card or a bad system board.

Try testing with cstm/mstm or xstm

You may wish to try another card depending on the results.

What you are seeing is almost certainly expected and documented. No HVD (High-Voltage Differential) SCSI, which was usually called FWD (Fast Wide Differential) back in the day, SCSI devices are supported at 11.23 and up. It's in the Release Notes for the OS. Almost all tapes libraries of that era use HVD SCSI.

Now things aren't a total loss because you can install LVD SCSI interfaces in your N box --- and they should be dirt-cheap on the used equipment market --- and use an LVD/HVD bus converters.

Paralan makes several and so does Blackbox.

Hi.

The server was previously running at 11.11 and the PCI SCSI cards were fine - The main use for one of them is a StorageTek L150 library with a SCSI attached rebotics.

So you are saying that this older stle wide SCSI connectors are not supported at 11.23 and I cant get a driver? FYI IOscan reads as follows...

ioscan - shows PCI SCSI cards as unknown:

0/8 ba Local PCI Bus Adapter (782)
0/8/0/0 unknown PCI SCSI (1000000f)
0/10 ba Local PCI Bus Adapter (782)
0/10/0/0 unknown PCI SCSI (1000000f)
0/12 ba Local PCI Bus Adapter (782)
0/12/0/0 unknown PCI SCSI (1000000f)
1/4 ba Local PCI Bus Adapter (782)
1/4/0/0 unknown PCI SCSI (1000000f)
1/10 ba Local PCI Bus Adapter (782)
1/10/0/0 unknown PCI SCSI (1000000f)

However fibre cards are OK:

1/12 ba Local PCI Bus Adapter (782)
1/12/0/0 fc HP Tachyon TL/TS Fibre Channel Mass Storage Adapter

ioscan -fn |grep -i pci

Take a look at the controllers.
Are there labels with "HVD" written on it?
Are the connectors 68 pin?

Good indicators for HVD SCSI.

Take out the cards and have a look at the part number to ensure the type.

HVD (F/W) devices are no longer supported beginning with 11.23 - but supported with 11.11.

[A. Clay Stephenson]

If you have A4800A or A5159A HBA's under 11.23, they are now boat anchors.

You can use A5149A, A5150A, or A5838A HBA's because they are all LVD devices.

Don't even think about trying to connect an LVD HBA to an HVD anything because HVD SCSI devices are incompatible with everything else --- including terminators.

If you must use this library then an LVD/HVD converter is really your only option.

[Paul Condren]

Oh well. Back to 11.11 it is then. THanks for the help.

[Paul Condren]

These cards are not 11.23 compliant.
