Re: Help with File System in UNIX
I doubt that Shawn's instruction will do you much good unless you do an lvextend first.
Follow Joseph's advive and use SAM->Disks & Filesystems->Logical Volumes.
It will walk you through the steps of extending a logical volume including the filesystem that is contained within it.
Hopefully, you have OnlineJFS and this can all be done 'on the fly'. Some filesystems e.g. /
can not be extended. You must also have space available.

Re: Help with File System in UNIX
attach the disk with your system.
As a root
#ioscan -fnCdisk
#insf -e (If you don't see word claimed)
#pvcreate /dev/rdsk/c?t?d?. (be careful this will remove anything from disk)
#umount /dir
vgextend vg0? /dev/dsk/c?t?d? (do more /etc/fstab to find out which vg belogs to /dir. vgdisplay -v vg?? to find all information about vg)
lvextend -L SIZE /dev/vg0?/lvol? (look /etc/fstab file for it)
extendfs -F hfs /dev/vg0?/rlvol?
mount /dir

Re: Help with File System in UNIX
The easiest way is to go into an Xwindow session (if you have it). Type in "sam" at a terminal prompt. This will start SAM (System Administration Manager).
Go to 'Disks and Filesystems' -> 'Logical Volumes'. Highlight the volume you would like to extend. If you are not sure which one it is, look all the way to the right and it will list the mount point.
With the volume highlighted, go to the 'action' menu at the top and select 'Increase Size'. It will then pop up a small window that will tell you how much space is available. Enter the new size that you want in the window and click ok. Remember this is the total new size, not how much you want to increase it by.
For example, if it is 1000 Mbytes and you want to increase it by 500Mbytes, enter 1500 at the prompt NOT 500.
If you have online JFS, or if no users are on that filesystem, it will handle everything else automatically. If SAM gives an error that it 'Could not unmount' the filesystem, that means that there are users on it. Just come back here and we'll be happy to let you know how to get around that.
I hope this helps,
Jared

Re: Help with File System in UNIX
I will list down the procedure for adding a new HDD and extending VG to this HDD and then extending lvols and filesystems. If U are not adding new HDD, remove those steps and use the remaining steps as per ur requirement.
physically add the new HDD.
#ioscan -fnC disk
Now it will list down all HDDs. Find out ur HDD's device file by using scsi ID. then
#diskinfo /dev/rdsk/cxtxdx
Make sure U selected device file is correct.
#pvcreate -f /dev/dsk/cxtxdx
#vgextend /dev/vgx /dev/dsk/cxtxdx
Now vg extended
#lvextend -L "size" /dev/vgx/lvolx
#umount "filsystem"
#extendfs /dev/vgx/rlvolx
#mount -a
If U need any more information. Please reply with details.
Best of luck
