RE: Tape Drive not Detected

I was having the same thoughts as I was reading the original post, even
going so far as to glance back at a spare 2749 on my credenza.

"IF" you managed to connect the cables up with a 2749, and I'm not sure
there is a cable that would properly connect due to the ends being
different, I'll bet Roberto is correct. Fried green tape drive unit.

Now there is a 5702 card that's not reporting in your config below and I'm
guessing if you cabled it with the cables that came off the tape device on
the P5 box you might be OK. What we don't know is if those cards are not
reporting due to card placement with respect the controlling IOP or not.
The IOP would appear to be reporting in so I'll guess it's card placements
that are the problem or you don't have another IOP to drive the tape
controller and the base IOP is full.

Just to start, you might have fried the LTO4 drive. The 2749 is an HVD
controller not an LVD one. Mixing HVD with LVD never ends well... And wait,
the 2749 does NOT have 2 ports, it's a single port HVD controller...
weird...
You need either a 5702 or 571A controller to drive the LTO4, of course you
have to hang that IOA under an IOP for LTO usage. Read the PCI/PCI-X
placement rules redbook for locations and requirements on building a config
for the 810.

Best Regards,

Roberto

Hi All,

I'm having an issue with connecting a tape drive to our iSeries box.
The box is a 9406-810 (yes, yes I know it's old, but I need to back it
up and restore it to the new server). The tape drive I have is a
3580-L43 single tape drive SCSI ID 0. The card I installed in the 810
is a 2749 which has two ports - SCSI ID 0, SCSI ID 1. I originally
removed this card from an
i520 box and installed it in slot C02 on the 810. I connected the LVD
cable from the LTO drive to SCSI PORT ID 1 on the interface card.
When I IPLed the system I would normally expect to see the tape drive
there when I do a WRKDEVD *TAP. However, there are no tape drives
present which would lead me to believe it might be misconfigured or I am

missing something.

Anyone have any ideas where I should start? I went into SST and
looked under packaging resources and there are two tape units listed
there, but neither of them are the model that I have (they are listed
as 3580-003 and
3580-001 - checking the serial number on both shows neither of them
are the device I am trying to set up).

Looking into the failed and non-reporting logical hardware resources I
see these items:
Description Type-model Status Resource Name
Storage IOA ? 5702-001 Unknown DC04
Storage IOA ? 2749-001 Unknown DC03
Tape Unit ? 3580-003 Unknown TAP03
Tape Unit ? 3580-001 Unknown TAP04

I'm a bit stuck on how to proceed....what are my next steps to try and
get this resolved so I can get the LTO operational?

Thankee-sai!
