Is it possible to clone a SCSI drive to SCSI2SD - KayBee - 02-17-2020
Hi Again Irixers,
I have a beat up O2 with a howling SCSI disk. I bought a SCSI2SD, which in theory could be plugged into the SCSI chain where the CD-ROM is supposed to be. I was hoping to clone the spinning disk to the SD card. Maybe this is impossible due to block sizes, etc. What do you guys think?
Thanks,
KB

SCSI2SD isn't supported on stuff like the O2 and up. Only 50-pin SGIs use it, and it's possible the O2's PROM may not permit that to be done.
You should just get a more modern SCSI disk.
As for cloning, yes, but it's not for the faint of heart. It involves xfs_dump and xfs_restore.

Technically, attaching the SCSI2SD with termination enabled to the CDROM flatcable should work, since both the SCA boot drive and the CDROM are on the same SCSI controller.
But aside from that, the SCSI2SD is simply too slow for what the O2 is capable of. Getting a fast and silent SCSI disk with SCA connector will provide you with much more performance.

Thank you. Back then, we used O2's for video work, so having a fast Seagate was critical. Now however I want to do a little C++ messing around, and so throughput isn't essential for me. So I hope there is a way to clone the drive.

As I said, there is. You basically have to run xfs_dump over the filesystem, then restore it to the new one. You can DD it, but that's far more risky and potentially destructive.
A 10k 147G HDD on ebay is like $25 though, so it's not that big of a deal to go that route.

Thanks Raion, I'll investigate. I may also get a SCSI HDD, just in case.

Here's a 300GB/15K for $20 shipped. I put these drives in my O2 and my Octane, and they're really nice.
** click --> HP 300GB 15K Drives, <-- click ** pull the drive from the tray and install it into the Octane sled, and you're in business.

Xfsdump/xfarestore are pretty easy to use, imo. I use them to create backups on a semi-regular basis.
Basic SGI disk imaging tutorial is here: http://www.cspry.co.uk/computing/Indy_admin/Indy_backup.html
Note that many 'recent' SGIs have diagnostics in ROM, so there is no IDE to copy using DVHtool. Xfsdump can be run on live disks. A better mount folder name for your new disk is 1, as the dump runs in alphabetical order. This all but eliminates the dump that is redumped into the /disk2 folder.

Greta, thank you Callahan, I'll start there.

You should be able to get a SCSI to SATA adapter on this website. I would recommend that you buy the adapter and then get a modern SATA drive. There is bootable Linux-based utility called Clonezilla that lets you clone hard drives really easily. You just download clonezilla for free and then install it onto a USB flash drive. If you do that you could take the SCSI drive out of your O2, put it in a modern PC using the SCSI to SATA adapter, also put the new SATA drive in your PC, and then use Clonezilla to copy the SCSI drive to the SATA drive. Once you have it copied, plug the new SATA drive into the SATA side of the adapter and then plug the SCSI side back into your O2 and it should work. You could use an SSD if you want. Ill also add the link to clonezilla's website.

Good luck! Happy cloning XD
