Hello,

You could use SAM/kernel configuration to enable the requested driver in your kernel. You must restart the system in order to build/install the new kernel.

Best regards,
Horia.

I can't see the driver "schgr" in SAM --> driver.

Hi Keynes,

Good day to you !
Please use SAM to put the 'schgr' kernel driver back to your system. Downtime is required for this task.

login as root > SAM > Kernel Configuration > Drivers > schgr > Add Driver(s) to Kernel

Hope this information can help.

Regards,
Adi.

Hi

I can't "schgr" in
"SAM > Kernel Configuration > Drivers >"

Is any other way ?

You should go to

SAM/Kernel configuration/Drivers

I suppose you had the driver in the kernel somewhere in the past, right?

Something was changed like a kernel rebuid...

What does it say to you:

kmsystem -q schgr

You could also check if the system find the corresponding hardware using ioscan.
(ioscan -d)

Hi Keynes,

Thanks for your update.
BTW, may I know what's the purpose of this 'schgr' driver ? Do you have this driver on your system previously ?

For what I understand, the 'schgr' driver is use to control the robotic arm on the library tape. Sometimes, the library need 'sctl' than 'schgr'.

Regards,
Adi.

I need this driver to install a MSL6060 tape drive. For enabling "autoch"

kmsystem -c Y schgr

would configure the driver in your kernel.

Then you must rebuild the kernel manually using mk_kernel (read manual page)

Bets regards,
Horia.

Manual rebuild of the kernel:

cd /stand/build
mk_kernel -s /stand/system -o /stand/vmunix

Hi Keynes,

Please execute the command from Horia 1st and see if the system can add the 'schgr' driver.

There's another thing that you need to have for the tape library, the 'stape' driver.

See output of the command below :

# tddiag|egrep -i stape
# tddiag|egrep -i sctl
# tddiag|egrep -i schgr

Last thing you need to take care is try to install the latest patch of SCSI tape (PHKL_34552) and its dependencies.

Hope this information can help.

Regards,
Adi.

Hi Hoira

I just tried to rebuild the kernal by the command you provided, but get errors as below

[bqyhp01]/stand/build # mk_kernel -s /stand/system -o /stand/vmunix
Provide configuration information for the "schgr" (SCSI changer) driver. * *

Re: "schgr" driver disappeared in kernel

Keynes Lee — Wed, 02 Jun 2010 08:37:13 GMT

Hi Adisuria

I already have PHKL_34552 installed. And I just verified there is no new version for this patch

>Provide configuration information for the "schgr" (SCSI changer) driver.

This means that system configuration file does not have the pertinent information about the driver. According to man autochanger ( http://docs.hp.com/en/B2355-60130/autochanger.7.html ),

"By default, schgr and eschgr are not included in the system configuration (/stand/system) file."

You must add that information in the system file.

vi system
add a line entry at the end of the file like this:

driver 1/0/4/0/0.2.2.255.0.0.0 sctl

(this is the HW path from your provided ioscan -f information)

Horia.

Of course...
