Re: Need to wipe some drives - HP-UX
for solaris /dev/zero and /dev/random I have used 10 times to get them ready for transport to the iron works where they get melted.
Haven't used HP-ux in quite a while and don't know if it carries over. I do know however you should use -p switch to actually force an overwrite of even the remapped sectors. Or some data can be recoverable.

The first link (containing hp9000) is correct for HP-UX servers. The second link (containing hp3000) is for the MPE operating system. While some HP servers where marketed with essentially identical hardware for both operating systems, as far as I know the D-series only supported HP-UX.

said by drjim :Boot it from a DBAN floppy, and select the option you want. I thought about that one, but was not sure DBAN would run on a PA-RISC processor. Add to that the box does not have a floppy nor any USB ports for a portable.
I've turned to running dd /dev/zero and will add /dev/random to that on Monday. The last thing I will do is a mediainit on the RAID, delete the LUNs, shuffle the drives and recreate the LUNs. The drives in question at one time contained critical business files. I really just want to be able to assure management that we can eBay them and be reasonably sure it would be cost prohibitive to try to resurrect any data. I think that method should do that.
The 18 gig drives I think are 10k but I know the 36 gig drives are 10k drives made in 2005.
Thanks y'all for all the suggestions. This one was driving me crazy searching for a solution. You all rock.  |

If you want to find out what release of UNIX it is running, type
uname -a
that's pretty standard for any UNIX system. I will come back with something like
HP-UX yoursystemname B.11.00 9000/887
The B.11.00 part (or similar) is the HP-UX release. Probably the best way is to just use random numbers and do several passes. If it takes a while you could just write a script using the POSIX shell or Perl... |

the dd will take several hours on an 18 gb drive, probably 7 hours plus depending on the speed of the drive. but it will hit ever sector and even one pass will be quite secure. if there is really important info on the drive, you could always set up a little shell script and do it 7 times, alternating between /dev/zero and /dev/random. that would meet US federal guidelines for wiping a drive. not even the nsa would be able to recover it. just let it run over the weekend, should be finished by monday morning. |

It was the format command and the option was 'purge' which would write alternative 1s and 0s at every accessible data location: see here
I'm not aware of a similar option in HP-UX, but it is easy enough to do the same with dd.

Definitely increase the blocksize to decrease the time. Something like this:
dd if=/dev/zero of=/dev/whatever bs=1M
You can consider using /dev/urandom (which will not block when entropy is exhausted) instead of /dev/zero. Depends on your level of paranoia.

dd if=/dev/zero sounds the best.
If you increase the block size, it should go a bit faster |

said by JohnInSJ :Do you need the disks? Well the idea is to attempt to sell the machine. I know, not a lot of market for it. It's probably worth more in parts. The 12H contains 12 36Gb 10k drives (Seagate Cheetahs around 2 years old) The computer part has 18gb drives and I'm not sure the age. |

said by timcuth :In Solaris, the standard format command has an option to destructively wipe a disk. My system administrator was telling me about it, but I don't remember the details. He said it runs a long time, too. Tim I have been checking the man pages, it was apparently not the format command.  Buf I am sure it was some standard part of the OS or its utilities. Sorry, it was a couple of years ago when he was telling me about it.

Do you need the disks? Because you could probably use a hammer or some really big magnets a lot faster. The dd should do it, but if someone was highly motivated a single write still leaves enough charge to recover the data - assuming we are talking NSA or somesuch.

said by evilghost :Run mediainit 20 times? I thought about that. Maybe not that many times though. Would almost be easier to put the drives in another box and run a pc wipe on them.
I started a dd if=/dev/zero /dev/rdsk/c0t10d0 or something of that nature this morning and it hasn't stopped (I can't remember verbatim). It's on a 18 gb and I have like 12 36 gb drives to do. |

1 edit | Hello everyone. I've been trying to find a way to wipe an old HP D370 with a 12H unit attached and it's been easier said than done. This box is running some version of HP-UX (tell me how to find and I'll tell you the version). It is a PA-RISC box.
Now then, I need to wipe the drives on the 12H as well as the main drives. I want to do the DoD wipe, you know the whole nine yards. But here's the problem. Just about every free wipe utility I find is for x86, Windows, or Linux. I have tried the suggestions at »unix.derkeiler.com/Mailing-Lists···056.html to no avail, yet. I've tried bcwipe but cannot get it to install (I think the compiler is too old) and the yack script referred to on that page will not complete (I'm still looking into that).
Anyone have any suggestions for a free disk wipe utility for HP-UX? I would try DBAN or the ultimate boot CD if I thought it would work and if I thought I could boot off CD with this thing.
TIA...if you need more info, I'll try to provide.
EDIT: Topic to make it more clear |
