Yes it is possible. You can remove 3 disks from server 1 and insert to free slots on Server 2. These drives will be shown as foreign drives in server 2 and you can import the foreign configs using iDRAC or PERC Configuration utility. Once imported virtual disk will be available in server 2. This will not impact other virtual disks on server 2. You can refer below link on importing foreign configuration using iDRAC and PERC BIOS iDRAC - [URL] PERC BIOS - [URL] Refer section "Importing Or Clearing Foreign Configurations Using The VD Mgmt Menu" on page 45 Note : it is recommended to backup your data before carrying out any maintenance tasks on the server
I have two servers PowerEdge R730 with the same hardware configuration, excepts the number of the disks, the actual scenario is: Server 1: 3 disks with 4 tera in raid. Server 2 :  8 disks  with 4 tera in raid. Server 2 faillover. I would like to know if is possible, unplugged the disks of SERVER 1 and plugged the disks of SERVER 2 without lost the configuration of the RAID of the SERVER 2, will work? To be more clean, i need the files in the Server 2, and i don´t can lost the data in this 8 disks.    I am using VMARE ESXI in this servers.  
Migrate disks from one server to another and dont lost raid configuration of 
raid is possible?
