SAS replacement in dell power edge 470

Safeen1969,

I am not certain the model of poweredge you are referring to, so would you help clarify that?

As far as the process to replace a disk will be either using a backplane or cabled drives. For the backplane, while the server is still on, you can remove  the failed drive, wait about a minute, then insert the replacement. It should start rebuilding automatically, but if not then assign it as a hotspare and it will. With cabled drives you would need to shut down the system to replace the drive before proceeding. 

Let me know if this helps.

heres the checklist Tiyaro DeepQuery came up with:

1. Identify the Failed Disk: Check your server's system management software or RAID controller interface (such as iDRAC, OMSA) for a degraded or failed status. The failed disk will typically have an amber light indicator.

2. Prepare for Replacement: Before replacing the disk, it is recommended to have a backup if possible, although RAID 10 provides redundancy that should protect your data.

3. Offline the Faulty Disk: Using OpenManage Server Administrator (OMSA) or through the RAID controller BIOS setup, you can manually offline the faulty disk to prepare for removal. This step ensures safety and prevents data corruption.

4. Physically Replace the Disk:

   • Pull the failed disk out of its bay while the system is running, as PowerEdge supports hot swapping.
   • Insert the new disk into the same slot. Make sure the replacement disk has equal or higher capacity.

5. Rebuild the RAID Array: Once the disk is replaced, the RAID controller should automatically start rebuilding the array using the new disk. This can be monitored via the RAID management tool you use (i.e., OMSA or BIOS).

6. Verify the RAID Status: After the rebuild process is complete, verify that the RAID status shows as optimal or normal within your RAID management tools.

Ensure that the PERC firmware is up to date to avoid any compatibility issues during the RAID rebuild process.
