Hi Mark, > >Have you actually configured the device online to the Linux LPAR? > Adding the device by means of this echo command *is* the first step to install this device, to switch it online (with another echo command in sysfs) is a next one.
The problem was: the echo command did just nothing, no error message - just nothing. In the meantime I know the reason. The device-bus-id I used is "0.0.0A08". And I typed "A", because an "A" is something else than an "a", at least I thought it so. But - "a" proved to be right ... echo worked only when giving him an "a". I must admit I don't know why, and I also don't know yet if it is going to function like this. thanks, Anna > >Mark Post > >-----Original Message----- >From: Linux on 390 Port [mailto:[EMAIL PROTECTED] >Behalf Of Fuhrmann Anna >Sent: Wednesday, April 12, 2006 7:12 AM >To: [email protected] >Subject: adding a qeth device > > >Hi dear List, > >I am about to add a hipersocket device to our Linux RHEL4 >LPAR/z-series. > > >The driver documentation suggests: > >echo ><read_device_bus_id>,<write_device_bus_id>,<data_device_bus_id> > > /sys/bus/ccwgroup/drivers/qeth/group > >But this command does not do anything visible, the file >"group" keeps being empty - and when listing the directory >"qeth", I get the following result: > >[EMAIL PROTECTED] qeth]# ls -la /sys/bus/ccwgroup/drivers/qeth total 0 >drwxr-xr-x 2 root root 0 Apr 11 13:55 . >drwxr-xr-x 3 root root 0 Mar 9 10:19 .. >lrwxrwxrwx 1 root root 0 Apr 11 13:55 0.0.0408 -> >../../../../devices/qeth/0.0.0408 >--w----r-- 1 root root 0 Apr 12 12:57 group >--w------- 1 root root 4096 Apr 11 13:55 notifier_register > >That is: the first device, an OSA-card, is a symbolic link >directly under .../qeth/. >So I suppose the echo command should nont contain "group". > >Is this a documentation mistake or am I just too much of a beginner? > >thanks, >Anna > >~~ >Dr. Anna Fuhrmann > >---------------------------------------------------------------------- >For LINUX-390 subscribe / signoff / archive access >instructions, send email to [EMAIL PROTECTED] with the >message: INFO LINUX-390 or visit >http://www.marist.edu/htbin/wlvindex?LINUX-390 > ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
