Maintaining soft partitions is no different from maintaining other logical volumes.
How to Check the Status of a Soft Partition
Read the Configuration Guidelines for Soft Partitions.
Use one of the following methods to check the status of a soft partition:
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node. Choose the soft partition that you want to monitor. Then, choose Action⇒Properties. Follow the onscreen instructions . For more information, see the online help.
To view the existing configuration, use the following form of the metastat command:
# metastat soft-partition
soft-partition
Specifies the name of the partition you want to check.
Example 13.3. Checking the Status of a Soft Partition
In the following example, the status of soft partition d1 is
checked. This soft partition includes two extents and is built on the RAID-1
volume d100.
# metastat d1
d1: soft partition

How to Expand a Soft Partition
When no other logical volumes have been built on a soft partition, you can add space to the soft partition. Free space is located and used to extend the partition. Existing data is not moved.
If a soft partition has been used to create another volume (for example, if it is a component of a RAID-0 volume), the soft partition cannot be expanded. In most cases, the same objective (providing more space for the device that contains the soft partition) can be achieved by concatenating other volumes onto the containing device. See Expanding Storage Capacity for more information.
Read the Configuration Guidelines for Soft Partitions.
Use one of the following methods to expand a soft partition:
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node. Choose the soft partition that you want to expand, then choose Action⇒Properties. Follow the onscreen instructions. For more information, see the online help.
To add space to a soft partition, use the following form of the metattach command:
# metattach [-s diskset] soft-partition size
diskset
Specifies the name of the disk set in which the soft partition exists.
soft-partition
Specifies the name of an existing soft partition.
size
Specifies the amount of storage space to add.
Example 13.4. Expanding a Soft Partition
The following example shows how to attach space to a soft partition.
The file system is then expanded using the growfs command
while the soft partition is online and mounted.
#mount /dev/md/dsk/d20 /home2#metattach d20 10g#growfs -M /home2 /dev/md/rdsk/d20
For more information on the growfs command, see Expanding a File System Using the growfs Command.
How to Remove a Soft Partition
Read the Configuration Guidelines for Soft Partitions.
Use one of the following methods to delete a soft partition:
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node. Choose the soft partition that you want to delete. Then choose Action⇒Properties. Follow the onscreen instructions. For more information, see the online help.
To delete a soft partition, use one of the following forms of the metaclear command:
#metaclear [-s diskset]#componentmetaclear [-s diskset] -r#soft-partitionmetaclear [-s diskset] -pcomponent
diskset
Specifies the disk set in which the soft partition exists.
soft-partition
Specifies the soft partition to delete.
r
Specifies to recursively delete logical volumes, but not volumes on which others depend.
p
Specifies to purge all soft partitions on the specified component, except those soft partitions that are open.
component
Specifies the component from which to clear all of the soft partitions.
