What I am trying to do is initialize two logical drives on a HP P400i embedded controller without a reboot of the system here my current Array config:

array A (SAS, Unused Space: 0 MB)

logicaldrive 1 (17.9 GB, RAID 5, OK)
logicaldrive 2 (17.9 GB, RAID 5, OK)
logicaldrive 3 (75.9 GB, RAID 5, OK)
logicaldrive 4 (25.0 GB, RAID 5, OK)

physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 72 GB, OK)
physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 72 GB, OK)
physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SAS, 72 GB, OK)

 array B (SAS, Unused Space: 0 MB) 

logicaldrive 5 (99 MB, RAID 0, OK)
logicaldrive 6 (68.2 GB, RAID 0, OK)

physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 72 GB, OK)

windows 2003 machine running the HpCISs2.sys driver version 6.20.0.32 . I have the ACU and ACU CLI tools installed version 8.28.13.0, P400i firmware version 2.74 .

Now what I'd like to do is removes the physical drive 1I:1:4 and delete the two logical drives in array B. then insert a new drive in to bay 4 that contains two new logical drives and have them show up in array B again.

So far after I remove the drive and delete the failed logical drives, I insert the new drive and run HPacucli rescan. I get the new drive to show up as unassinged physical drive but I cant figure out now to "for lack of a better word" mount the 2 logical drives on the new unassinged disk.

If I reboot the system the array controller picks up the new fourth drive and creates Array B with the drives without problem but I'd really like to not have to reboot the server.

Any ideas?
