rp2430 cannot detec DAT72

[Hasan_9]

Hello Everybody,

I tried to use a HP DAT 72 with my rp2430 and HP-UX 11iv1.I connected the DAT to one of external SCSI ports of server. I break the server before loading the kernel. I executed ‘SEA’ and server detected a SCSI device on that port. I booted the server from my hard disk. When boot process was finished HP-UX did not detect the tape at all. I executed ioscan –funC tape, ioscan –fun but nothing was about the tape. On that SCSI port nothing was detected. What should I do?
Please Advice.

Hi ,

Check you have stape driver in the kernel .
If stape driver is not present then include it , regenerate the kernel reboot and it should be okay.can use sam for this.

Contact your HP HW guy.

There was a defect (which might not be the same as yours) that was caused because of a power issue on some DAT 72s.

Not sure that we've seen this with HP supplied DATs, but it might be the same thing.

hi,

check the drive is terminated properly at the end of the bus.

Also check the drivers are included through SAM, stape and all the tape drivers. then do a full ioscan
#ioscan
and then insatll the device files

#insf -e

full ioscan again the tape should be there. If not run the diagnose missing tape from SAM, see if that can find it.

Also is the system upto date patch wise? there were patches for the dat drives if you have an unpatched system,

Andy

pls check SCSI type and ensure that it match with your server!

Hi.

Verify if you system have install the drive tape2 in the sam in the Kernel Configuration-Drives.

If the drive is out, you have that install the drive in the menu Actions - Add drive.

Warning, this process need reboot

I hope Help

Thank you Everybody,
I added stape and tape2 in my kernel. However nothing was changed. I was installed GOLDQPK11i_B.11.11.0412.5.depot and HWEnable11i_B.11.11.0412.5.depot on my server too.

This has the stape driver support for the dat72.

to diagnose missing tape in sam

go to peripheral devices
select tape drives
then tab to actions and pres return, then select diagnose missing tape drive.
