i want to test disk access.
the test objective is to insure that data can be written to,and read from,the hard drive .
test procedure using IPU board as host .
i want to rd,wr,rd tests to the first, middle and last blocks of the test disk .

But sometime middle and every time at the last blocks i can't rd or write , it's depend f capaciti of HD .

 

[SYAR2003]

A format
then several mkfs ( to all used capacity)
and fsck will do

 

[ozgur74]

i don't understand ..
is it possible that the ipu version which not perited ?

 

[SYAR2003]

How are you testing then , by witch commands.

 

[ozgur74]

Ipux in mode x

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)

If you don't know about ipux
What are you doing in there anyway (just playing..)

 

[ozgur74]

thanks syar ...
you are testing just 64MB ...

Who are playing ?

 

[SYAR2003]

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.

Hello SYAR,

kindly can you tell me what is the IPUX and how can i enter that mode, i didnt work before with IPU cause i start with NIU, so id like to know what is the IPUX.

thnx

 

[SYAR2003]

Its the same as NIUX for the NIU board.
Direct access to the minix filesystem.
