"The following conditions prevent you from expanding file systems: ....When the file system is root (/), /usr, or swap."
In this article, we will be growing the root filesystem, but not while it is in use. This, and the need for contiguous cylinders are essential to the success of the procedure.
Please note that depending upon the configuration of the boot disk, the ability to grow the root filesystem may not be possible without additional preliminary work which is not covered in this document.
It is strongly recommended that a backup of the root filesystem be performed prior to implementing this procedure.
Also, experience with the Disksuite or Solaris Volume Manager products and their command line utilities is recommended.
This document may not provide ALL the commands necessary to perform the task, so some additional commands or steps may be necessary.
All references in this document to "SVM" should be taken to refer equally to Solstice DiskSuite[TM] and Solaris[TM] Volume Manager.
