Adding physical disk to server poweredge R740XD
Hello ,
I am using a Dell PowerEdge R740XD server with RAID5. Now, I want to copy all my data on some physical storage and for same, I ordered dell internal hard disk( External hard disks would have been more portable but too slow )
Now, the plan is, I want to insert these hard disks, make a copy of all data and remove these hard disks to store at a safer place.
I don't want them to be added to the RAID5 system.
please tell me
1) Do I need to shut down the system in order to add new physical disks?
2) What shall I do so that server doesn't add them into RAID5 space automatially?
3) after adding a hard disk, do I have to trigger some commands for my server to read them?

Hello
All of this depends on the storage controller that you are using, I don't see the model of storage controller mentioned.
If you have a backplane then you don't need to shut down to insert/remove drives. If the drives are cabled then you need to shut down.
No storage controller will add the drive to the RAID 5 automatically. Some storage controllers, like the S-series, may automatically put the drive into non-RAID mode. Most storage controllers won't do anything with the drive, it will just sit in a ready state.
Maybe, if you are using an S-series the drive may be put into non-RAID mode and be available for use. Most of our storage controllers will require that you put the drive into a single drive RAID 0 or non-RAID, if supported. Once the drive is either a virtual disk member or in non-RAID mode it will be presented to the operating system. You will need to configure the drive in the OS before it can be used. Typically, you will need to format the drive and assign a drive letter.
