When you created the mirror for the root (/) file system, you should have recorded the alternate boot device as part of that procedure. In this example, c0t1d0 is the problem device. # metadb flags first blk block count a m u 16 1034 /dev/dsk/c0t0d0s4 a u 1050 1034 /dev/dsk/c0t0d0s4 a u 2084 1034 /dev/dsk/c0t0d0s4 Now try metareplace d0 -e c1t0d0s0 and see if it resynchronizes the mirror ... (It should copy data from d2 to d1) Go to Solution 6 Comments LVL 7 Overall: Determine which state database replicas are unavailable. # metadb -i If one or more disks are known to be unavailable, delete the state database replicas on those disks.
Note – This procedure only works to recover soft partition information. This step is especially important if the root (/) file system is mirrored. The device is not a root device for any boot environment; cannot get BE ID. Use the format command or the fmthard command to partition the disk as it was configured before the failure.
