Answer

From the output, I notice that all the 4 lunpaths to the disk56 is in FAILED state. (Ideal state should be Active or Standby)

 

Extract from command output:
# scsimgr get_info all_lpt -D /dev/rdisk/disk56

You may also check the LUN state for other disks(disk57,58,59,60,61,62,64,94) reported in the error message. 

 

I suspect these failed LUN's are causing the issue. fixing this lun issue would all the make_net_recovery to work fine.
