Accessing DLT4000 autochanger

[Randy Tarrier]

Hello,
I've seen variations of this question, but I'm still having a problem creating a device file for my autochanger. I have a K460 w/11.0, DLT4000 2/28 connected via scsi. I can see the scsi pass-thru for the robotic arm in an ioscan, but can't see the autoch driver. I've enabled spt,spt0, autoch, sctl drivers in the kernel.
Output from ioscan:
# ioscan -fC autoch
#
# ioscan -fC spt
spt 0 10/4/4.6.0 spt CLAIMED DEVICE HP C5177-4000
Output from lsdev:
# lsdev -d schgr
Character Block Driver Class
231 29 schgr autoch
# lsdev -d sctl
Character Block Driver Class
203 -1 sctl ctl
# lsdev -d spt
Character Block Driver Class
144 -1 spt spt
Checking the admin menu on the dlt shows the 'lib' device has scsi id 6
I created a driver via mksf:
mksf -H 10/4/4.6.0 -m 0x006000 -r /dev/rscsi/c4t6d0
This shows that it recognizes the hdw path as an spt driver:
# ll /dev/rscsi/c4*
crw-rw-rw- 1 bin bin 144 0x006000 Jan 3 15:46 c4t6d0
The following shows the driver isn't talking to the device:
# lssf /dev/rscsi/c4t6d0
lssf: Don't know how to handle driver "spt"
# strings /etc/ioconfig|grep sctl
sctl
sctl
sctl
sctl
# strings /etc/ioconfig|grep schgr
# strings /etc/ioconfig|grep spt
spt0
#
Stm sees it as:
20 10/4/4.6.0 SCSI Media Changer (HPC5177) It does allow for exercise of the changer.
Because stm can talk to it, and none of the drivers in /dev/diag have a minor # that matches any of the above drivers,it must be using the sctl drivers to communicate.

I've installed PHKL_22759.

So I'm probably overlooking something elementary, but I'm just too deep in the forest......Any ideas anyone?

Sanjay, I already tried the mc cmd, it gave me: ERROR: No such device or address

Michael, could you please resend your attachment?

Hi Randy,

Do a ioscan. in that you should make a note of the device file mentioned under schgr. this is /dev/rac/cxtydz for example. you have to use this file to manipulate the changer, move DLT's around in the library.

Hope this helps.

Hi Randy,

you should use "ioscan -fn" .

hope this helps.
