You have to mention that the partition detection process is - independent of the disk type - a hierarchical process. Those partition detection parts high in the hierarchy are asked first if they would like to try and possibly take the disk as theirs. Only if they deny or fail in a proper way the disk gets passed to the next layer. The DASD specific part is very low in the hierarchy (which is OK since it is quite uncommon for none s390 systems to have a DASD device). But this leads to the point that most of the other partition tables overrule the DASD part. If there is for example a msdos style partition table that states you have an empty disk without a partition on the FBA DASD, than the DASD partition detection will never be asked and there will be no default partition. So you always have to take care if you recycle previously used disks.
Thanks Stefan, now I understand the technical background much better. -- Regards, Juha ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
