FBA DASDs must be treated differently from regular DASDs, i.e. to create a partition, you should use fdisk, parted etc. and not fdasd. (In reply to comment #8) > Please excuse my ignorance, but I am working under the assumption that FBA > devices should be partitioned using DASD partitioning table just like the > ECKD drives (using fdasd tool). If this is wrong, and e.g. ms-dos partition > table should be used for FBA devices, we need to change the logic that > decides which partitioning tables to use in the installer. > > I can reproduce this bug, in a sense that kernel manages to read DASD > partitioning table, and partitions, off FBA device including volume label, > yet userspace tools parted and fdasd cannot. > > syslog: > Jan 11 07:07:27 kernel: [ 156.679393] dasd-fba 0.0.0104: New FBA DASD > 9336/10 (CU 6310/80) with 59025 MB and 512 B/blk > Jan 11 07:07:27 kernel: [ 156.682792] dasdb:VOL1/ 0X0104: dasdb1 dasdb2 > > # cat /proc/dasd/devices > 0.0.0104(FBA ) at ( 94: 4) is dasdb : active at blocksize: 512, > 120884827 blocks, 59025 MB > > # cat /proc/partitions | grep dasdb > 94 4 60442413 dasdb > 94 5 585920 dasdb1 > 94 6 59856256 dasdb2 > > # fdasd -p /dev/dasdb > > fdasd error: Unsupported disk type > /dev/dasdb is not an ECKD disk!
