Pegais 2-4x2TB dosks. I have just replaced a drive that died and am working through the rebuild pricedure on the Promise Utility. It stops with the warning "Failed to start rebuild: all the logical drive on the array are eitehr offline or online" (attached)

The Mac Disk Utility will not bring it online.

OK, I think the reason my RAID5 array was offline, and therefore not on my desktop, was that I had set the replacement disk to Unconfigured and restarted the computer. When I changed it back to Passthrough, the disk appeared on my desktop. I was then able to change it back to Unconfigured and begin the Rebuild process. At the speed it is going it might take all day. Fingers crossed.

Hi Ian,

Many new disks today have a 'passthru' status, I'm not sure why.

But you cannot rebuild to a drive with a passthru status. The simplest way to start a rebuild is...

  • remove the passrthru status and make the drive status unconfig
  • Make the drive a spare, a rebuild should start
