Associating a Hot Spare Pool With Volumes

How to Associate a Hot Spare Pool With a Volume

1. Check Prerequisites for Creating Solaris Volume Manager Elements.

2. To associate a hot spare pool with a RAID 5 volume or submirror, use one of the following methods:

   • From the Enhanced Storage tool within the Solaris Management Console, open the Volumes and choose a volume. Choose Action->Properties, then choose the Hot Spare Pool panel and Attach HSP. For more information, see the online help.

   • Use the following form of the metaparam command:

     metaparam -h hot-spare-pool component

     -h

     Specifies to modify the hot spare pool named.

     hot-spare-pool

     Is the name of the hot spare pool.

     component

     Is 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—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—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.

How to Change the Associated Hot Spare Pool

1. Check Prerequisites for Creating Solaris Volume Manager Elements.

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 detach the new hot spare pool by following the 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

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

     component

     Is 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—Changing the Hot Spare Pool Association

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

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

Example—Removing the Hot Spare Pool Association

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

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