The following sections show how to perform maintenance tasks on hot spare pools.
To view the status of a hot spare pool and its hot spares, use one of the following methods:
From the Enhanced Storage tool within the Solaris Management Console, open the Hot Spare Pools node and select a hot spare pool. Choose Action⇒Properties to view detailed status information. For more information, see the online help.
Run the following form of the metastat command:
# metastat hot-spare-pool-name |
The following example shows sample output from the metastat command on a hot spare pool.
# metastat hsp001 hsp001: 1 hot spare c1t3d0s2 Available 16800 blocks |
The metahs command can also be used to check the status of a hot spare pool.
For information on the hot spare pool states and the possible actions to take, see Hot Spare Pool States.

Use the following form of the metastat command to view the status of the hot spare pool:
# metastat hot-spare-pool-name |

To replace the hot spare, use one of the following methods:
From the Enhanced Storage tool within the Solaris Management Console, open the Hot Spare Pools node and select a hot spare pool. Choose Action⇒Properties. Then choose the Hot Spares panel. Follow the onscreen instructions. For more information, see the online help.
Use the following form of the metahs command:
# metahs -r hot-spare-pool-name current-hot-spare replacement-hot-spare |
Specifies to replace disks in the named hot spare pool.
Specifies the name of the hot spare pool. You can also use the special keyword all to change all hot spare pool associations.
Specifies the name of the current hot spare that will be replaced.
Specifies the name of the slice that will replace the current hot spare in the named hot spare pool.
For more information, see the metahs(1M) man page.
In the following example, the metastat command shows that the hot spare is not in use. The metahs -r command replaces the hot spare, /dev/dsk/c0t2d0s2, with the hot spare, /dev/dsk/c3t1d0s2, in the hot spare pool, hsp003.
# metastat hsp003 hsp003: 1 hot spare c0t2d0s2 Broken 5600 blocks # metahs -r hsp003 c0t2d0s2 c3t1d0s2 hsp003: Hotspare c0t2d0s2 is replaced with c3t1d0s2 |
In the following example, the keyword all replaces the hot spare, /dev/dsk/c1t0d0s2, with the hot spare, /dev/dsk/c3t1d0s2, in all its associated hot spare pools.
# metahs -r all c1t0d0s2 c3t1d0s2 hsp001: Hotspare c1t0d0s2 is replaced with c3t1d0s2 hsp002: Hotspare c1t0d0s2 is replaced with c3t1d0s2 hsp003: Hotspare c1t0d0s2 is replaced with c3t1d0s2 |
