Erase Harddisk in SRM

[Marco Dubini]

Hi folks
is there a possibility to formate or erase the harddisk in the SRM?

You cannot erase the data, but you can override the data with the exer command. For example:

exer -p1 -bc 4 -a â wâ -d1 â 0x5aâ dka0

The following command writes the hex pattern 5A to every byte of blocks 1, 2, and 3 â using a packet size of 2048. The value of 2048 for the packet size is derived from multiplying the â bc value (block per I/O) of 4 by the default â bs value (block size) of 512.

Hi Ivan
i have tried it, but it does not work on my ds20e

I tipped in the command and the SRM answers:
dka0.0.2004.1 is write protected
file open failed for DKA0


Sorry but I am a newbie on SRM :)

Hi Marco,

why is it you want to delete the disk from srm? The first 16 blocks are read-only anyway. Depending on the controller you could run the setup in its bios and format the drive from there.

Please post
show dev
from the srm console.
Is the server not bootable anymore?
From the shelll you could do it with the dd command.

I have not done this before, so try this:

exer -p1 -sb 17 -bc 4 -a "Â Â w"Â Â -d1 "Â Â 0x5a"Â Â dka0

So you will skip the first 16 blocks.

You can also try with:

exer_write

Also, use kill_diags.

Sorry for the wrong characters:

exer -p1 -sb 17 -bc 4 -a "w" -d1 "0x5A" dka0

Attached is the SRM reference.

What Ivan writes look good.
You could even start from block 10 since counting starts with 0 and is specified in hex.
