Make sure that you have a current backup of all data and that you have root access.
To attach additional components to a RAID 5 volume, use one of the following methods:
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node, then open the RAID 5 volume. Choose the Components pane, then choose Attach Component and follow the instructions. For more information, see the online help.
Use the following form of the metattach command:
metattach volume-name name-of-component-to-add |
volume-name is the name for the volume to expand.
name-of-component-to-add specifies the name of the component to attach to the RAID 5 volume.
See the metattach(1M) man page for more information.
In general, attaching components is a short-term solution to a RAID 5 volume that is running out of space. For performance reasons, it is best to have a “pure” RAID 5 volume.
# metattach d2 c2t1d0s2 d2: column is attached |
This example shows the addition of slice c2t1d0s2 to an existing RAID 5 volume named d2.
For a UFS, run the growfs command on the RAID 5 volume. See Volume and Disk Space Expansion.
An application, such as a database, that uses the raw volume must have its own way of growing the added space.
