- Command string (Refer below for supported commands) - UART device name (say, "/dev/tty00") - Specify image file path for upgrade - Specify image region. (G, A, B for MSS regions, g, a for FPGA region) Following commands are supported: -um - Upgrade MSS image -uf - Upgrade FPGA image -gmr - Get MSS running image region -gfr - Get FPGA running image region -gmv - Get MSS running image version -smr - Select MSS running image region -sfr - Select FPGA running image region -help - Dispay help SMF MSS upgrade You can upgrade SMF MSS using the following steps: To find out what region is running, use the gmr option. • If MSS is running in region A, use the region B image to upgrade the MSS. • If MSS is running in region B, use the region A image to upgrade the MSS. • If MSS is running in region G, use the region A image to upgrade the MSS. Upgrade mss A-region when mss is running in G-region: ./smarttool -um /dev/ttyS0 _SMF_MSS_v1.41_A_region.bin Upgrade mss B-region when mss is running in A-region: ./smarttool -um /dev/ttyS0 _SMF_MSS_v1.41_B_region.bin Upgrade mss A-region when mss is running in B-region: ./smarttool -um /dev/ _SMF_MSS_v1.41_A_region.bin 1 Copy all the binaries needed for the upgrade into a local directory. Figure 6. Copy all needed binaries 2 Check the MSS region using the smarttool -gmr /dev/ttyS0 command. 72 Dell EMC DAIG-OS tools
