How to Associate a Hot Spare Pool (Command Line)

After checking the prerequisites ("Prerequisites for Creating DiskSuite Objects"), and the preliminary information ("Preliminary Information for Creating Hot Spare Pools"), use the metaparam(1M) command to associate a hot spare pool. Refer to the metaparam(1M) man page for more information.

Example -- 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 a mirror, d0. The metastat command shows that the hot spare pool is associated with the submirrors.

Example -- Associating a Hot Spare Pool with a RAID5 Metadevice

# 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 RAID5 metadevice named d10. The metastat command shows that the hot spare pool is associated with the RAID5 metadevice.
