1. what kind of disks and connections - SAN, local, or what?
2. Hardware - Solaris box type v440, m4000, or what?
Please give us specifics. It may be possible to do this easily.
You cannot format the system disk and be logged directly into the system disk. You have to have booted from other media or use an interface like XSCF, for example.
Well, he mentions booting from CD. Yes, you can boot from and installation disk in general. I share Jim's fustration at the lack of any hardware info. With a sparc system you just do "boot cdrom -s" from the OK prompt. The system should boot into single user mode from the Installation disc. It will give you a root prompt. And yes you can run format.
However, under Solaris 10, I sure do not see any "purge" command in the format utility. There is a "format" command. It would probably do an adequate job on a SCSI disk.
I would probably do:
I understand what dd is doing much more clearly than the format utility which I find to be a little opaque.
Here at work we have a very powerful demagnetizer which can wipe a disk in few seconds. We do that and throw the drive in a bin to await final destruction. Every few months a guy comes by with a "chipper". It is like the chippers used to turn tree branches into sawdust but it is intended for disk drives. It chops the disks up. Not quite to dust, but it turns them into chunks. It looks kinda like a breakfast cereal. He says he can recycle the chunks somehow. That must be a interesting trick.
Disks are not very expensive these days, but the data on them can be priceless. This is why we are required to use physical destruction. You might want to consider that.
The analyse/purge option will write multiple patterns to every sector of the drive(s) (will take a long time to run) after which no data can be recovered even using the most sophisticated methods. The number of patterns written exceeds the specification of the UK MOD and US DoD standards.
I think you should be able to verify the disk surface from within format and there is an option to do a destructive test. There was certainly one to do a non-destructive test when I used to have a Solaris server.
Is that an option? An alternate would be to slice the disk differently and then install a default Solaris and create filesystems from the other slices. That would probably clobber most data pointers.
Of course if you are super paranoid or have a regulatory or contractual obligation then you can remove and destroy the disks with a degausser (not sure on cost) or with one of the recycle companies that turn it all into high mineral compost.
What level of certainty do you need that no-one can read your data? A drill through the casing is a pretty good deterrent over data recovery.
hi,
can someone please guide me if there is any special hardware to use when we need to terminate an E1/T1 link on a Solaris10 box. I have a number of boxes and these all are located at longer distances. the only connectivity is the E1 links between these far location locations.
Would it be... (0 Replies)
I have network with x computers which is divided in three subnets A, B ,C. All three subnets need can't access to internet because my old router -> R.I.P.
Probably best solution is to get new router and set up back internet connection but that is not good enough for me.

Hi guys. I plan to study Perl in near future, and Im just wondering, is Perl installed in Solaris with minimal install?
Cheers.
Edit: looks like I have found out Perl is installed with minimal install :)

New Solaris box how do I tell if its raided

Got a new machine in that was set up prior to receipt, how can I tell if the drives are raided and if so what raid level was used on Solaris 8?

Hi,
I need a clarification.
Is there any difference between AIX box and Sun Solaris box?
The bzip command with -c option works in AIX box and the same does not work in Sun Solaris box.
Can anyone please explain if there is an implementation difference in both these boxes for the shell... (1 Reply)
We are getting the following error:
warning: pm: Can't set power level of TSI, gfxp to level 0
The machine is running Solaris 8. I think it is a SUn 220R box.
Any ideas what this means? (2 Replies)

I picked up an Ultra 10 for a great price, installed Solaris 10, and aside from running the usual network services I'm wondering, what can I use this box for? What are the killer apps for Solaris that you can't run on anything else? It's got the Elite3D graphics, and while I'm sure they're no... (1 Reply)
