I have a four-drive RAID 5 array running in a Compaq Proliant server with integrated SmartArray controller.

The array (4x18GB)It is way to big for what I need, so I would like to remove one of the drives and use it somewhere else.

It looks like the Compaq Array Configuration Utility will in fact let you remove a drive and reconfigure an array without destroying data on the volume. (There are only about 10 GB on the volume, so it there is more than enough space available.

Of course, Iwould never try this without doing a verified backup first, but has anyone ever used ACU to remove a drive from an array without blowing away the volume?

Thanks,

Joe

I have run into problems doing this I recomend two good backups just in case but this can be done. I dont know what kind of array controller you are using eg 3200,5400 but I would recomend a firmware update on the controller if there is one available before you do this also you may not be able to do this with any model below the 3200 I dont know how the person who gave the reply before this one could awnswer you so easily befor knowing more specifics if it is an actual integrated controller like an lc2 wich goes in to a slot that looks like a memory slot of some type then i would have to research weather or not this is possible. Is this an ml\dl 370 or 320 or somthing else? also I can be reached at sstilen@midcomp.com
