Example 17–4 Associating a Hot Spare Pool With Submirrors

# metaparam -h hsp100 d10
# metaparam -h hsp100 d11
# metastat d0
d0: Mirror
    Submirror 0: d10
      State: Okay        
    Submirror 1: d11
      State: Okay        
...
 
d10: Submirror of d0
    State: Okay        
    Hot spare pool: hsp100
...
 
 
d11: Submirror of d0
    State: Okay        
    Hot spare pool: hsp100
...

The -h option associates a hot spare pool, hsp100, with two submirrors, d10 and d11, of mirror, d0. The metastat command shows that the hot spare pool is associated with the submirrors.

Example 17–5 Associating a Hot Spare Pool With a RAID 5 Volume

# metaparam -h hsp001 d10
# metastat d10
d10: RAID
    State: Okay        
    Hot spare pool: hsp001
...

The -h option associates a hot spare pool named hsp001 with a RAID 5 volume named d10. The metastat command shows that the hot spare pool is associated with the RAID 5 volume.
