Okay, this is not real work, been working on my RHCT, and decided to
test what I can do on a PC to the zLinux platform.
I am trying to create a RAID-1 Array (two disks mirroring each other) in
a zVM environment. I created two minidisks in zVM and am trying to
format them on the zLinux side, using fdasd (instead of fdisk on the PC
side).
But I see no option to format "fd" the disks, with the interactive, it
keeps asking for partition number (here is the display):
(/root)#fdasd /dev/dasdk
reading volume label ..: VOL1
reading vtoc ..........: ok
Command action
m print this menu
p print the partition table
n add a new partition
d delete a partition
v change volume serial
t change partition type
r re-create VTOC and delete all partitions
u re-create VTOC re-using existing partition sizes
s show mapping (partition number - data set name)
q quit without saving changes
w write table to disk and exit
Command (m for help): t
Disk /dev/dasdk:
cylinders ............: 750
tracks per cylinder ..: 15
blocks per track .....: 12
bytes per block ......: 4096
volume label .........: VOL1
volume serial ........: 0X0205
max partitions .......: 3

Has anyone played with "software" RAID on the mainframe Linux?
