Wiping SAS drives in 4 x HP SANs which are being returned

4 x Store Virtual  3200 SANs are being returned because they're terrible.  We need the ability to wipe 44 SAS 2.5" disks within a reasonable amount of time.  The platform for the storage controllers is a dual redundant/HA flash storage controller which uses two SD cards to write data on for the appliance OS.  I'd like to live boot some linux and just DD the drives, but I'm not even sure how to.  Anyone have any ideas?

Well, ...

If the drives are configured RAID, then it will not be possible to erase all the sectors on the drive.  RAID controllers reserve part of the drives for their own use.  Do you require complete erasure, or would "all the user area" be good enough?

Not at all sure you can run Linux on a storevirtual 3000 so I think you'll have to take the disks out of the caddies and put them in a server to erase unless you just wipe each target LUN. Look at the controllers http://partsurfer.hpe.com/ShowPhoto.aspx?partnumber=840219-001 , you can't run Linux on that.

To be fair,

HP is running linux on it.  So it is feasible.

The Five Tenets of the Most Secure Backup

Data loss can hit a business in any number of ways. In reality, companies should expect to lose data at some point. The challenge is having a plan to recover from such an event.

Yes, but it's embedded Linux and probably tied down. admittedly I haven't got a controller to see if there's a USB port on it you could boot from. There may be a possibility of getting to a Linux shell through the CLIQ utility command but HPE don't publish that publicly.

If you follow the post on a lights-out boot up, it will actually reveal the support hardware code required to log into the shell.  The problem is, is the shell is limited and doesn't have things like dd and so forth.  

I think we're going to take them all to the junkyard and have the crane magnet operator give them a good pull...

So sad to destroy good drives with a magnet when you can shove a SAS HBA or RAID controller into a PC and wipe them with that. May as well smash them with a hammer as you won't get away with returning the units to the supplier with every one of the disks dead.

If you use this Acme Drive Decommissioner, you can sell raffle tickets to the IT staff.

But seriously, there is a solution.  Reviewing older discussions here on EE, there is a PC controller that will handle single SAS drives and you can then use any drive erase software you like.

I have not been able to find a TX2650 (PCI version), but there is one TX4650 (PCI Express version) on fleabay.

Drivers are available up through Windows 7, and for linux.

Dr. Klahn, there are over 100 different SAS cards that would do the job, no need for that particular one. a RAID controller works just as well as a dumb HBA. Most probably they have an old ProLiant server they could put them in to wipe them (except the caddies would probably need swapping to physically fit).

Dr. KlahnPrincipal Software EngineerCommented:
I think there may be an invalid assumption somewhere, which is that (a) most RAID controllers will handle a single drive and that (b) they will handle it as it would be handled on a PC, with all sectors accessible.

In any case, this solution is known to work.

Neither (a) nor (b) is needed to overwrite the whole disk. They are not trying to recover data, just overwrite it and any RAID controller will write metadata on some of each disk and user data on the rest.

Hi,

it's a bit of work but you can reimage the Store Virtual  3200 SANs.

The reimaging process permanently clears the system of all data and configuration settings. Before
proceeding, make sure that any data that must be retained is backed up.

Read up on page 119 of the HPE StoreVirtual 3200 Storage User Guide

Cheers
