I have DS4000 IBM SAN Storage ( aka FastT Storage )

One of my disks has failed and I had a hot spare disk covering all the arrays. As the disk failed, immediately the hotspare disk took over the failed disk ( see the JPEG in the attachment )

My Question: How can I make the hotspare which now took over the failed disk, to become part of the array and it should be a permanent disk ( instead of a hotspare disk as you can see + sign below the disk ) ?

a quick question:

I have one free disk plugged in the SAN Storage. It is not part of any array or hotspare coverage ( I have removed it from hotspare coverage -- )

Can I just remove the disk while the SAN is powered on and plugged into the failed disk ?


Do I need to shutdown the SAN Storage and remove the disk ?


1) You can remove / unplug an ununsed powered Disk from the SAN STORAGE and use it in place of failed disk without powering off or anything

2) You can make the HOTSPARE a permanent disk provided this option is supported by the firmware level and software of DS4000
