   • Use the following form of the metaparam command:

     # metaparam -h hot-spare-pool component

     -h

     Specifies to modify the named hot spare pooll.

     hot-spare-pool

     Specifies the name of the hot spare pool.

     component

     Specifies the name of the submirror or RAID-5 volume to which the hot spare pool is being associated.

     See the metaparam(1M) man page for more information.

Example 17-4 Associating a Hot Spare Pool With Submirrors

In the following example, 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.

# 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
...

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

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

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

How to Change the Associated Hot Spare Pool

Before You Begin

Check Prerequisites for Creating Solaris Volume Manager Components.

1. Become superuser.
2. To change a volume's associated hot spare pool, use one of the following methods:

   • From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node and choose the volume. Choose Action⇒Properties. Then choose the Hot Spare Pool panel. Detach the unwanted hot spare pool and attach the new hot spare pool by following the onscreen instructions. For more information, see the online help.

   • Use the following form of the metaparam command:

     # metaparam -h hot-spare-pool-name RAID5-volume-or-submirror-name

     -h

     Specifies to modify the hot spare pool named.

     hot-spare-pool

     Specifies the name of the new hot spare pool, or the special keyword none to remove hot spare pool associations.

     component

     Specifies the name of the submirror or RAID-5 volume to which the hot spare pool is being attached.

     See the metaparam(1M) man page for more information.

Example 17-6 Changing the Hot Spare Pool Association

In the following example, the hot spare pool, hsp001, is initially associated with a RAID-5 volume,d4. The hot spare pool association for the volume is then changed to hsp002. The metastat command shows the hot spare pool association before and after this change.

# metastat d4
d4: RAID
    State: Okay        
    Hot spare pool: hsp001
...
# metaparam -h hsp002 d4
# metastat d4
d4: RAID
    State: Okay        
    Hot spare pool: hsp002
...

Example 17-7 Removing a Volume's Hot Spare Pool Association

In the following example, the hot spare pool, hsp001, is initially associated with a RAID-5 volume, d4. The hot spare pool association is then changed to none, which indicates that no hot spare pool should be associated with this volume. The metastat command shows the hot spare pool association before and after this change.

# metastat d4
d4: RAID
    State: Okay        
    Hot spare pool: hsp001
...
# metaparam -h none d4
# metastat d4
d4: RAID
    State: Okay        
    Hot spare pool:
