Hello,

I have an old IBM x226 server type 8648 with (2) 50gb 320 scsi hard drives configured in a hardware raid 1 with a 320 raid controller.

The system is ancient and I need to upgrade the hard drives with the least amount of downtime.

My plan would be to add two new 146gb scsi drives, configure them as a raid 1 as well so now there are two raid 1's in the system, all active.

Clone the source raid 1 to the destination raid 1, remove the old raid, and boot from the new set.

Does ABR support this or would I need to break the source raid, and then clone the data to the newly configured raid 1 drives?

Would I be able to do this in a live environment (clone to new raid), then shutdown, remove the old raid, and boot up or would the system need to be rebooted with a bootable disc to clone to the new drives?

I'm a little lost on which version would support this as I'm not interested in any file backups or time-managed backups. I simply need to upgrade the drives.

Thanks for your help.

I would suggest the more prudent thing to do would be to use ABR11.5 to make a complete disk image of the drives and restore that to the new drives. ABR will be able to recognise a RAID.

If you want to clone you will need to purchase the Universal Restore as well.

Making an image has less potential hassles than clones can have, you also have the luxuary of being able to retain and manipulate a disk image compared to a clone.

Alright so ABR it is then.

I'm trying to keep it to the 2 drives. For security reasons I cannot bring in my own third drive to store the backup on so I only have the two new drives to work with. If I go the image route, I assume I can leave the source raid 1 intact, then store the image on one of the new drives. Afterwards, pull the source raid, install the 2 new drives and set the blank one as the primary boot drive, restore the backup with the start disc, and then create a raid 1, wiping data on the on the drive containing the image and letting it rebuild, correct?

If this were a modern workstation or even a modern server I wouldn't be stressing about it, but since this system is so old and their local system house refuses to touch it, I'd like to cover all my bases before going to war :)

Much appreciated.
