Hi all,  You can use the service command "svc_diag -s sas" Probably best to redirect the output to a file as the output is extensive. Once you have the output, locate this section:  FBECLI> sepls:  Type    Obj ID      ID    Object Info    Lifecycle State  Downstream      Drives                                                           Objects ------------------------------------------------------------------------------------------------   Here you will see the rebuild status and % complete. Example from my lab below. In this case, the pool was originally built on 0_0_0 0_0_1 0_0_2 0_0_3 0_0_9 I removed 0_0_9 to show you the rebuild process. You can see 0_0_4 took over and the RG is currently rebuilding. The current percentage is shown next to the drive that is being rebuilt, in this case, 0_0_4:   FBECLI> sepls:  Type  Obj ID      ID   Object Info  Lifecycle    Downstream            Drives                                     State        Objects ------------------------------------------------------------------------------------------------ RG    0x170 :368  8    RAID5        READY        363 364 365 366 367   0_0_0  0_0_1  0_0_2  0_0_3  0_0_4 (REB:8%)   Hope this helps.
