Mark Post has previously give a very good explanation, here it is again ( with thank's to Mark ! )
/****************************************************************/ /* Add a disk the right way, making it online */ /****************************************************************/ I would be more accurate to say that /etc/zipl.conf is not the _sole_ way to define which DASD volumes come online at boot time. The parameters there are used if they exist, but YaST uses a different method when setting this up. This is true for SLES10 as well as SLES11. If a DASD volume is needed to mount the root file system (whether a single partition or an LVM LV spanning many DASD volumes), the main startup script in the initrd gets dasd_configure commands added for each one of them. For any DASD volumes that are unrelated to the root file system, the only thing that gets looked at is (for SLES10) /etc/sysconfig/hardware/hwcfg-dasd-*, and (for SLES11) /etc/udev/rules.d/51-dasd-*. The thing about the dasd_configure command is that it will create those files for you, whether in /etc/sysconfig/hardware, or /etc/udev/rules.d/, depending on what version of the distribution you're running. So, the easiest way to add a volume to your system via the command line is: dasd_configure busid online diag/notdiag sample: dasd_configure 0.0.0500 1 1 dasdfmt fdasd if ECKD and not FBA mkinitrd zipl Mark Post _________________________________________________ Tore Agblad System programmer, Volvo IT certified IT Architect Volvo Information Technology Infrastructure Mainframe Design & Development, Linux servers Dept 4352 DA1S SE-405 08, Gothenburg Sweden Telephone: +46-31-3233569 E-mail: [email protected] http://www.volvo.com/volvoit/global/en-gb/ -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of Antonio Jesús Lozano Bonilla Sent: den 18 april 2011 21:28 To: [email protected] Subject: Re: vdisk i think so.. if your list of devices is short or not get the new dasd (vdisk)..
