Where or how is a disk address mapped to /dev/dasdx (where "x" is a, b, c)? I ask because at install time I am -certain- that I instructed the partitioner to make the 200 disk to be /dev/dasda1, the 201 to be /dev/dasdb1, and 202 to be /dev/dasdc1. (I have a screen-shot of the VNC windows, but won't include it here.)
After installation completes I see: linux024:~ # cat /proc/dasd/devices 0.0.0201(ECKD) at ( 94: 0) is dasda : active at blocksize: 4096, 600840 blocks, 2347 MB 0.0.0202(ECKD) at ( 94: 4) is dasdb : active at blocksize: 4096, 600840 blocks, 2347 MB 0.0.0200(FBA ) at ( 94: 8) is dasdc : active at blocksize: 512, 409600 blocks, 200 MB How can I change the DASDA, B, and C settings around? Or am I missing a step in the expert partitioning, during set-up?
