Enter ipux
mode x
Format the disk low level
(if scsi id=3)
format 3 ll
make the devices if not already there
check with
list /DEV
You should have device SC31 ,SC32 and so on.
mkdev /DEV/SC31 231
mkdev /DEV/SC32 232
mkdev /DEV/SC33 233
mkdev /DEV/SC34 234
mkdev /DEV/SC35 235
mkdev /DEV/SC36 236
mkdev /DEV/SC37 237
mkdev /DEV/SC38 238
mkdev /DEV/SC39 239
Now you have devices for nine filesystems
make the file systems
mkfs /DEV/SC31 FFE0 FB00 400
mkfs /DEV/SC32 FFE0 FB00 10400
mkfs /DEV/SC33 FFE0 FB00 20400
mkfs /DEV/SC34 FFE0 FB00 30400
mkfs /DEV/SC35 FFE0 FB00 40400
mkfs /DEV/SC36 FFE0 FB00 50400
mkfs /DEV/SC37 FFE0 FB00 60400
mkfs /DEV/SC38 FFE0 FB00 70400
mkfs /DEV/SC39 FFE0 FB00 80400
All these will be 64MB size.
Test them with checkdisk.
fsck /DEV/SC31
.
.
.
fsck /DEV/SC39
If all fsck tests ok , disk is fine .
format the disk again.
other commands:
scinfo
(basic info on the scsi disk)
fsinfo
(file system info from the disk)
mode x
Format the disk low level
(if scsi id=3)
format 3 ll

There will be nine 64MB partitions
thats max devices on one SC .
The md cant hold more than nine , neither can the IPU .
Max partition size on a IPU is 64MB
addressing is four bytes FFFF~65535kb
So any further out on the disks sectors you will never come
using it in a MD.
