Dear Sun Managers,

problem. Both the state of the submirror of d120 shows
needs maintenance. This is pretty urgent and currently
the system is down. Would much appreciate if someone
can provide me the exact steps and commands on how to
bring the submirror to OK state.

hap> metastat -s dmp

State: Needs maintenance
Submirror 1: dmp/d122
State: Needs maintenance
Pass: 1

Also, if it safe to recreate the metadevice and can
some validate whether the following commands is fine.

# metadetach -s dmp dmp/d120 dmp/d120
# metaclear -s dmp d120
# metainit -s dmp d120 -r d1s0 d2s0 d3s0 d4s0 d5s0
