Hi!

I have a Sun Cluster 3.1 configured for Solaris 9 (12/03).
The cluster has a Sun StorEdge 3510 array diskset.

The metastat shows that there is a submirror needs maintenance:

sogds/d160: Mirror
   Submirror 0: sogds/d161
     State: Okay
   Submirror 1: sogds/d162
     State: Needs maintenance
   Pass: 1
   Read option: roundrobin (default)
   Write option: parallel (default)
   Size: 209694720 blocks (99 GB)

sogds/d161: Submirror of sogds/d160
   State: Okay
   Size: 209694720 blocks (99 GB)
   Stripe 0:
       Device Start Block Dbase State Reloc Hot Spare
       d6s0 0 No Okay No

sogds/d162: Submirror of sogds/d160
   State: Needs maintenance
   Invoke: metareplace sogds/d160 d7s0 <new device>
   Size: 209694720 blocks (99 GB)
   Stripe 0:
       Device Start Block Dbase State Reloc Hot Spare
       d7s0 0 No Maintenance No

It said that I should invoke the command metareplace to replace it with a
new <new device>.
But how do I know what are the devices available?

I also tried to enable the slice by entering the following command,

# metareplace -s sogds -e sogds/d160 d7s0
metareplace: emanode-a: d7s0: No such file or directory

Do you what could be the problem?
