Filosofo — Thu, 13 Feb 2003 10:18:11 GMT

Hello,
I have a K570 with install HP-UX 11.00
I have connect a Optical Library but I see the picker UNCLAIMED.
What are the name of the drivers?

Thanks

You have to add the sctl driver into the kernel and to create the device yourself:

# lsdev -d sctl --> note major number

# mknod /dev/picker c MAJOR 0x001000

sctl is install.
If I execute ioscan -fn i see:

unknown -1 8/4.6.0 UNCLAIMED UNKNOWN HP C1160F

Thanks

That is normal, please create the picker device file and try to work with it (see man mt and/or uma).

It is not necessary to have the picker CLAIMED !!! If you have created the device file:

Trying to access the picker. Need to create devicefile for that:

# lsdev -d sctl
Character Block Driver Class
203 -1 sctl ctl

# mknod /dev/picker c 203 0x056000

05 is instance number of ext_bus (scsi controller), 6 is scsi id of picker
(J1160J)

You should be able to work with the picker device:

# mc -p /dev/picker -q
Vendor ID : HP
Product ID : C1160J
Product Rev : 1.49

Hello,
I have create special file like said you.....
and I execute your command
mc -p /dev/picker -q
I see the following output:
ERROR: No such device or address

sctl is only driver that I must load in the kernel?

Thanks for helps and patient

If the "mc" command doesn't work try to use "uma":

# uma -ioctl /dev/robot
/dev/robot> move S1 D1

There exist a other driver which must be used by DDS Autoloaders, called spt:

# lsdev | grep spt
spt 75

# mknod /dev/robot c 75 0x056000

Perhaps the device file you created was wrong. Please notice:

minor no: 0xEESL00

EE = Interger No. of the ext_bus
S = SCSI ID of the device
L = LUN of the device

please check if the minor no. you has used is correct.

You first need to know the type of *internal* bus, HSC/GSC or NIO/HPPB.

NIO/HPPB use scsi1 or scsi3 for the *interface* driver ("INTERFACE" in ioscan output).

NIO/HPPB should use the spt driver for the picker. See the scsi_pt(7) manual page how to configure this driver, including the required mknod command.

HSC/GSC should use the sctl driver for the picker. See the scsi_ctl(7) manual page how to configure this driver, including the required mknod command.

If you need more help, then post the "ioscan -f -H ..." output where "..." is the harware path of the *interface*.
