A computer system includes a BMC and a host of the BMC. The BMC redirect, through a BMC communication channel, a local media including a disk management tool to a host of the BMC as a particular drive. The host is a storage device connected to one or more storage drives. The disk management tool is configured to prepare a storage area of the one or more storage drives for installation of storage service on the host. The storage service managing a RDMA controller at the host. The BMC configures the host to boot from the particular drive. The BMC sends a first instruction to the host instructing the BMC to reboot. The BMC receives from the host a command for reading the disk management tool. The BMC sends the disk management tool to the host.
