This question was asked yesterday, too. See the commentary (suggested methods) here:

Re: increase root file system size
Why do you think you need to increase root? It is already at 1 GB in size, which is oversized in my opinion, and only 300MB or so is in use.
This file system looks to be in OK shape to me.

Re: increase root file system size
The root filesystem should be static, that is, does not grow and contains nothing but /etc, /dev and /bin. In fact, the / directory should not have any files at all, and certainly no applications or data directories should exist in /. There are a lot of baadly written application installers that place large files in /. Find the misplaced directories like this:
du -kx / | sort -rn | head -10
The two largest directories under / should be /sbin and /etc and for 11.23, about 300 MB occupied for an average system, possibly 500-600 MB for a system with hundreds of LUNs. So your current usage is normal and the 1GB size is reasonable. But wanting to increase it? The / filesystem is far too critical to place random files and directories. It is why moving root's HOME directory is so important. One small mistake by a root user and the entire computer will have to be reinstalled. Applications are installed in /opt, large data directories have their own volume groups and lvols.
With all that said, trying to increase / is very invasive and would require a number of risky steps for a novice system administrator. It is far safer to enforce good sysadmin practices.

Re: increase root file system size
Take an ignite backup or your host. Re-ignite it but this time when you go to the tab for the Fielsystems change the size for the root VG.
Cheers,
