Format/Verify Disk

[TYP3R]

Hi Guys

I've got a machine with Tru64 installed. All i need to do is format/verify those disk that in the server. It's the fist time that i've used Tru64 but so far i got to this point: But dont know if i'm right or not

hwmgr scan scsi
hwmgr show scsi

Here on i get a list of scsi device

dsk0...........
dsk1............
dsk2............

dd if=/dev/disk/dsk1 of=/dev/null bs=256k
dd if=/dev/zero of=/devices/dsk/dsk1 bs=256k

i keep getting an error with /dev/disk/dsk1: No such file or directory and /devices/dsk/dsk1: No such file directory

Can any1 tell me what am i doing wrong ? and what is the correct procedure to test these disk..

Thanks in Advance

will

To "format" a disk, you should use the mkfdmn and mkfset commands, like this:

mkfdmn /dev/disk/dsk1c dsk1c_domain
mkfset dsk1c_domain dsk1c
mount dsk1c_domain#dsk1c /mnt/disk

To test a disk you can use the diskx command.

Will,
Welcome to the Tru64 Forum.
Be sure to use 'google' to find earlier relevant posts. For example:
google: +tru64 +dd +site:itrc.hp.com +disk

For dd from zero or to null you want to use the RAW device file. (rdisk)

And under TRu64 disks are presented with 8 partitions: You need to pick one, and in this case you probably want "c" being "the whole disk"
Check ls /dev/rdisk/dsk1*

Use 'disklabel dsk1' to verify.

The commend you want to issue to clear the disk is probably (currently no access to test system):

dd if=/dev/zero of=/dev/rdisk/dsk1c bs=256k

Mind you, some folks argue that this is only good enough to clear data away from non-devious folks and that one really needs to shake the buits or physically damage the disk to make it completely unrecoverable.
Using multiple passes with 'erase patterns', perhpas from /dev/random is desired according to those folks.
google: +tru64 +dd +site:itrc.hp.com +erase

I did look at some early theard but its the "dsk1c" that got me.. None of them mention that c is for the whole disk.. Any way Hein van den Heuvel thanks for the help

Hi Will,

the command Hein posted will reult in an error because the first 16 sectors are read-only. They should be skipped with the oseek option.
dd if=/dev/zero of=/devices/dsk/dsk1c bs=16 oseek=1


greetings,

Michael
