UCS c240 m3s server

Good afternoon I’m currently trying to setup a UCS c240 m3s server and am experiencing the following issue.

The disk size is (4002432) the problem I’m having is the disk shows (Background Initialization) when I try to remove the disk I receive the following message.

Raid Configuration: One of the logical disk is running some operation. Current action cannot be done.

I’ve tried goolging the issue and have been unsuccessful on finding an answer I need to get this taken care of as soon as possible any assistance would be deeply appreciated.

Things that I’ve tried to resolve the issue 1: delete the raids then tried to reconfigure the disk replaced the disk and tried the same steps with no success.

Hello Dale,

Can you please provide screenshot of the error message ?

What happens if you try to clear the configuration of the controller and verify the outcome ?

UCS c240 m3s server

After RAID configuration is complete on the drives, the system may try to initialize (format) the new RAID array. When this happens, the current initialization progress can be seen from the Web BIOS screen. Wait for the background initialization to complete before proceeding with any of the subsequent server configuration steps such as installing ESXi. Cisco has noticed that a slow initialize can take up to 95 minutes or more to fully complete for array sizes of 1 TB+ used in a UCS C240 M3 Rack-Mount Server TRC1 deployment.
