Applies to:

Sun Solaris Volume Manager (SVM) - Version 11.9.0 and later
Solaris Cluster - Version 3.0 and later
Oracle Solaris on SPARC (32-bit)
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on x86-64 (64-bit)
Oracle Solaris on x86 (32-bit)

Goal

Solstice Disk Suite (SDS) and Solaris Volume Manager (SVM) have traditionally allowed you to increase the amount of available space on mirror/concat/raid 5 and soft partition.
The aim of this document is to provide you with practical examples on how to achieve the goal of increasing the file system (fs) size by adding new LUNs for any of the possible configurations.

Before increasing the fs size, you will need to increase the metadevive underlying layer by adding new free space on it.
With this document free space will be added by adding new LUNs to the actual config.
Such a change can be achieved online without umounting the fs.

The following are different metadevices type you may deal with:

A) mirror
B) concat (concatination)
C) stripe
D) raid 5
E) soft partition

 
For expanding fs on an existing LUN refer to:
<Document 2018655.1> Solaris Volume Manager (SVM) How to 'growfs' an UFS on Top of a SVM mirror/concat/soft partition by Expanding an Exiting LUN

It is always recommended to have a valid backup of the filesystem available before making such kind of changes.
