C1716T on HP712 WS

[Peter Mills_3]

How do I get this WORM drive to work on an HP712 running HPUX 11.11.

ioscan sees it but I cannot access the media!

Thanks

Got to be a kernel driver issue. What is the exact model? C1716T? I ask because 'spt' is listed for this device in this ioscan:

http://docs.hp.com/cgi-bin/fsearch/framedisplay?top=/hpux/onlinedocs/B9106-90013/B9106-90013_top.html&con=/hpux/onlinedocs/B9106-90013/00/00/62-con.html&toc=/hpux/onlinedocs/B9106-90013/00/00/62-toc.html&searchterms=driver%7cC1716T&queryid=2003985-072814

If the STATE=CLAIMED then try using 'dd':

dd if=/dev/dsk/cXtYdZ of=/tmp/temp_file bs=2048 count=1000

Thw C1716T is not a simple disk drive, it is an optical ukebox so there are two drivers, one for the disk and another for the robotic arm. The disk driver is a standard SCSI disk driver but the robotic arm needs SCSI passthrough setup. You'll need to look up the details for spt in http://docs.hp.com

Thanks for the response.

I know that the drive normally lives in a JB.

Sadly the JB is dead and unlikely to recover.

A C1716T drive was removed from a JB and connected to a 712 in an attempt to allow the data from the media to be recovered, albeit slowly and then written to another media.
I've tried dd

I agree that it looks like a kernel issue.
spt will be unlikey to resolve this.

ioscan shows:-
disk 3 2/0/1.0.0 sdisk CLAIMED DEVICE HP C1716T

command executed:-
dd if=/dev/dsk/c0t3d0 of=/tmp/temp_file bs=2048 count=1000

response:-
/dev/dsk/c0t3d0: No such device or address

/dev entry:-
brw-r----- 1 bin sys 31 0x003000 Mar 24 2003 c0t3d0

Something is either missing or it ain't going to work, any ideas?

Thanks again

Peter

When you took the disk out of the JBOD the device address changed. Have you rebooted? During reboot is when devices are sensed and new device files created. The no response message from 'dd' confirms this.

Try:

ls -lrt /dev/dsk

This lists dates in order, first to last. If no other devices changed then the C1716T disk will be last.

Try these commands as well:

ioscan -fnkC disk

ioscan -fnkC spt

ioscan -fnk | grep -i spt

Look for the new device file.
