Query with HP9000 K380 connectivity

Hello,

I would appreciate your comments on a query I have with an HP9000 K380

We do have one small problem, and I am unable to get my head around whether there are any solutions to it or not.

The way that HASS enclosures have been setup are as follows :

* - 4 internal 4Gb disks are on 10/0.x

* - Top HASS enclosure in same rack as server is on 8/12.x

* - Bottom HASS enclosure in same rack as server is on 8/8.x

* - Top HASS enclosure in other rack is on 10/16/4.x

* - Next two HASS enclosures in other rack are SCSI chained on 10/4.4.x (0-15 i.e. we lose one slot)

* - Bottom two HASS enclosures in other rack are SCSI chained on 10/8.4.x (0-15 i.e. we also lose one device. We are using double height 9's in bottom HASS anyway)

In terms of tape, we have two single ended devices chained on 10/4/8.2.0 (a storagetek 4280 device) and 10/4/8.0.0 (A DLT 4000s device)
These work absolutely fine without any problems.

The problem comes when I connect a fast wide DLT 7000 to the remaining 'spare' FW connector on the backplane. This assigns 10/0.0.0 to the device (it has a SCSI ID of 0)
When I did this, we started experiencing system hangs and panics etc etc. I have ascertained that this is because a tape is connected on the same bus and the internal disks which apparantly is a big no-no and it understandable unsupported. I have subsequently disconnected the device and we are replying on performing Oracle backups to a seperate 'diskbackup' area until such time that we can find a solution.

My question is therefore - is there any option available to us to connect the DLT7000s Fast wide device without changing the existing device ID's and affecting the extensive LVM layout currently on the server.

I am concious that we only have a two port HSC Expansion I/O card and although port 3 (8/12) and port 2 (8/8) have cards in, I can see that port 1 (8/4) and port 0 (8/0) are empty. The problem here though is that when Malcolm installed this HSC card - we confirmed that ports 1 and 0 CANNOT have additional cards added as there is nothing to plug them into on the HSC expension card itself.

I've got another 4 port HSC expansion card from another server (A3489-60002) and the actual card DOES have 4 connectors and therefore could take 4 cards, but before the server went onto contract, I tried to fit this card and it would not - the actual metal plate the the A3490-60002) card is connected to is different.

This just leave the next slot - labelled up as 12/ and 14/ entitled processors 4 and 5 or expansion i/o. The server has a total of 6 processors so I'm therefore not sure that this is an option.

I've attached an ioscan from the server and would appreciate any help if possible.

Many thanks

Russell Gould
