Maintaining soft partitions is no different from maintaining other logical volumes.
Before You Begin
Read the Configuration Guidelines for Soft Partitions.
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
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 component: d100 state: OKAY size: 42674285 blocks Extent Start Block Block Count 0 10234 40674285 1 89377263 2000000 d100: Mirror Submirror 0: d10 State: OKAY Read option: roundrobin (default) Write option: parallel (default) Size: 426742857 blocks d10: Submirror of d100 State: OKAY Hot spare pool: hsp002 Size: 426742857 blocks Stripe 0: (interlace: 32 blocks) Device Start Block Dbase State Hot Spare c3t3d0s0 0 No Okay
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.
Note - 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.
Before You Begin
Read the Configuration Guidelines for Soft Partitions.
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
Specifies the name of the disk set in which the soft partition exists.
Specifies the name of an existing soft partition.
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.
Before You Begin
Read the Configuration Guidelines for Soft Partitions.
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] component # metaclear [-s diskset] -r soft-partition # metaclear [-s diskset] -p component
Specifies the disk set in which the soft partition exists.
Specifies the soft partition to delete.
Specifies to recursively delete logical volumes, but not volumes on which others depend.
Specifies to purge all soft partitions on the specified component, except those soft partitions that are open.
Specifies the component from which to clear all of the soft partitions.
Example 13-5 Removing a Soft Partition
This example shows how to delete all soft partitions on c1t4d2s0.
# metaclear -p c1t4d2s0
