dd4 C6369A issue wuth HPUX v2 11.23 RX2600

[Tom Bellavia]

I have a issue when I try to install the dds4 drive using a scsi u320 interface. The system reports IO errors and I can't see the drive.
These are the errors:
mpt_analyze_ioc_status SCSI Protocol Error, resetting bus. Instance = 4, lbolt 8
SCSI Ultra320 0/3/1/0 instance 4: Driver initiating SCSI bus reset.
mpt_analyze_ioc_status SCSI Protocol Error, resetting bus. Instance = 4, lbolt 1
SCSI Ultra320 0/3/1/0 instance 4: Driver initiating SCSI bus reset.
mpt_analyze_ioc_status
Can it be a bad drive?
The on-board scsi gets similar errors. I have tried several cables and terminators.

Did you terminate the bus?
Check the cable for bent pins.

Be careful if using the onboard connector - do you have a disk in the upper slot?

[Tom Bellavia]

I used a separate card. The card has a & b. I tried both ports and I tried a differant PCI slot. I tried several terminators as well as verified their LVD SE.
Nothing, Same error. I am thinking the RX2600 does not like that drive.

[Torsten.]

Yes, the card was in the second slot from top.


Did you check the cable? Maybe the device end has this 68pin connector. These pins are very easy to bent.

[Tom Bellavia]

Yes, the cable is fine. I have tried (2) cables. The system is fine when I remove the tape unit. It could be the tape drive.

[Steven E. Protter]

Shalom,

These tape drives do fail.

That is what I think happened in this instance.

Based on the fact cables did not help.
