Mount point expansion /app

Hi Guy's

I have mount point called /app with size 10 GB from EMC SAN

/dev/dsk/emcpower2g    9.6G   9.8M   9.5G     1%    /app

I have expanded the size from SAN level to be 20 GB
But the mount point still is showing 10 GB

Can anyone advice us how to can I expand the new space on /app to be 20 GB without impacting /app data

If you are using UFS, growfs would be the right way.

Yes I'm using UFS ..

Please explain the growfs command step by step and be aware I'm doing the expansion from SAN STORAGE level I want the expansion to be appeared on the /app without effecting the data ...

Pls advice and explain ..

Thanks..

I tried what you said but no luck ..

I got it below is the procedure

How to point expand mount point in Solaris

This is the procedure I used to grow a UFS Solaris Volume Manager (SVM) with EMC Powerpath after a Clariion LUN expansion.

1. Unmount the filesystem.
2. type format -d <disk> where <disk> is the name of the emcpower device
3. once in format, type p followed by p to show the current partition table. Make a copy of the partition table as it will be overwritten!
4. type q and then type
5. Next, pick option 0 autoconfigure. Warning: This will overwrite your current partition table.
6. type p to display and modify the new partition table. After you make any necessary modifications to disk slices, type l, then q
7. growfs /dev/rdsk/<disk> where <disk> is the name of the emcpower device
8. Mount the filesystem.
