B. Solaris Volume Manager Quick Reference
Caution - Do not create volumes or hot spares larger than 1 Tbyte if you expect to run the Solaris software with a 32–bit kernel or if you expect to use a version of the Solaris OS prior to the Solaris 9 4/03 release. See Overview of Multi-Terabyte Support in Solaris Volume Manager for more information about multiterabyte volume support in Solaris Volume Manager. |
Caution - Solaris Volume Manager does not warn you if you create a hot spare that is not large enough. If the hot spare is not equal to, or larger than, the volume to which it is attached, the hot spare will not work. |
Before You Begin
Check Prerequisites for Creating Solaris Volume Manager Components.
From the Enhanced Storage tool within the Solaris Management Console, open the Hot Spare Pools node. Then, choose Action⇒Create Hot Spare Pool. For more information, see the online help.
Use the following form of the metainit command:
# metainit hot-spare-pool-name ctds-for-slice
Specifies the name of the hot spare pool.
Specifies the slice being added to the hot spare pool. The option is repeated for each slice being added to the hot spare pool.
See the metainit(1M) man page for more information.
Note - The metahs command can also be used to create hot spare pools.
Example 17-1 Creating a Hot Spare Pool
# metainit hsp001 c2t2d0s2 c3t2d0s2 hsp001: Hotspare pool is setup
In this example, the hot spare pool hsp001 contains two disks as the hot spares. The system confirms that the hot spare pool has been set up.

To add more hot spares to the hot spare pool, see How to Add Additional Slices to a Hot Spare Pool. After you create the hot spare pool, you need to associate it with a submirror or RAID-5 volume. See How to Associate a Hot Spare Pool With a Volume.
Before You Begin
Check Prerequisites for Creating Solaris Volume Manager Components.
From the Enhanced Storage tool within the Solaris Management Console, open the Hot Spare Pools node. Choose the hot spare pool you want to change. Choose Action⇒Properties. Then, choose the Hot Spares panel. For more information, see the online help.
Use one of the following forms of the metahs command:
# metahs -a hot-spare-pool-name slice-to-add
# metahs -a -all hot-spare-pool-name slice-to-add
Specifies to add the slice to the specified hot spare pool.
Specifies to add the slice to all hot spare pools.
Specifies the slice to add to the hot spare pool.
See the metahs(1M) man page for more information.
Note - You can add a hot spare to one or more hot spare pools. When you add a hot spare to a hot spare pool, the hot spare is added to the end of the list of slices in the hot spare pool.
Example 17-2 Adding a Hot Spare Slice to One Hot Spare Pool
In this example, the -a option adds the slice /dev/dsk/c3t0d0s2 to hot spare pool hsp001. The system verifies that the slice has been added to the hot spare pool.
# metahs -a hsp001 /dev/dsk/c3t0d0s2 hsp001: Hotspare is added
Example 17-3 Adding a Hot Spare Slice to All Hot Spare Pools
In this example, the -a option used with all adds the slice /dev/dsk/c3t0d0s2 to all hot spare pools configured on the system. The system verifies that the slice has been added to all hot spare pools.
# metahs -a -all /dev/dsk/c3t0d0s2 hsp001: Hotspare is added hsp002: Hotspare is added hsp003: Hotspare is added
