Re: "schgr" driver disappeared in kernel

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.

Re: "schgr" driver disappeared in kernel

kmsystem -c Y schgr

would configure the driver in your kernel.

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

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

Re: "schgr" driver disappeared in kernel

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.

Re: "schgr" driver disappeared in kernel

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

Re: "schgr" driver disappeared in kernel

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)
