HP-UX: Expands logical volume size using SAM
System Administration Manager (SAM) and System Management Homepage (SMH)
System Administration Manager (SAM) has been a great help to configure HP-UX. Through SAM, a system administrator can easily modify the system’s users, groups, backup, recovery, display, kernel configuration, peripheral devices, tasks, as well as disks and file systems. However, the SAM is not included in the latest HP-UX anymore, replaced by a fancy and full-graphic interface that is called as System Management Homepage (SMH). But not to be afraid, this SMH is, in fact, as strong as SAM. The main different is that the SMH requires a web browser and is not accessible through TELNET/SSH protocol. Yes… yes… I know that everyone, today, can aford a laptop with web browser, as the matter of fact, an Acer Aspire One, HP Mini or Asus EEE PC is good enough for this task.
Expands Logical Volume Size Using SAM
Anyway, let’s get back to the topic, which is `expands logical volume size using SAM`, assuming that an old version of HP-UX is still being used. To begin with, the intended logical volume has to be `umount`-ed.
# umount /xxxxx4
And then, execute `sam`
# sam
Starting the terminal version of sam...
To move around in sam:
- use the "Tab" key to move between screen elements
- use the arrow keys to move within screen elements
- use "Ctrl-F" for context-sensitive help anywhere in sam
On screens with a menubar at the top like this:
------------------------------------------------------
|File View Options Actions Help|
| ---- ---- ------- ------------------------------- ---|
- use "Tab" to move from the list to the menubar
- use the arrow keys to move around
- use "Return" to pull down a menu or select a menu item
- use "Tab" to move from the menubar to the list without selecting a menu item
- use the spacebar to select an item in the list
On any screen, press "CTRL-K" for more information on how to use the keyboard.
Press "Return" to continue...
And then, choose `Disks and File Systems` continued with `Logical Volumes`

It may take a few minutes before the extending process completed; this is the right time to enjoy a cup of coffee. Once the process is completed, exit from SAM and re-mount the logical volume.
# mount -a mount: /dev/vg01/lv12 is already mounted on /xxxxx1 mount: /dev/vg00/lvol8 is already mounted on /var mount: /dev/vg00/lvol7 is already mounted on /usr mount: /dev/vg00/lvol6 is already mounted on /home mount: /dev/vg00/lvol5 is already mounted on /tmp mount: /dev/vg00/lvol4 is already mounted on /opt mount: /dev/vg00/lvol1 is already mounted on /stand #
Now the logical volume should have its new size. This can be verified using the `df -k` command.
