You can have a try with dft_replace_sys SCSI_BUS_ID. This is pretty simple, single command & done. What it does behind the scene is that it detaches / un-mirrors the specified disk. Asks you to replace the faulty disk with new one. No need to do that in your case (as long as disk is not physically bad). Just say you have done it. Enter CONT to continue. It will reformat, remirror & that's it. As usual you can see the status via dft_show_status. REMEMBER: The SCSI_BUS_ID you specify should be the one that has Nds_Maint, otherwise you will land up in soup, as the good one will also go into Nds_Maint. Also check the syntax of dft_replace_sys. I would prefer to have a good backup around. HH835 works well too as Richard said, but I just find this one simpler, especially if you have a more than one partition in Nds_Maint. It just struck me - that if we have 2+ partitions in Nds_Maint, 1 from esp0 & another from esp1. Never seen such a case but then HH835 looks like a answer.
