Increase lvol size in HP-UX

Let’s assume that you want to increase 1Gb of the /dev/MyVG /lvol1 device (mounted as /filesystem):
# bdf /filesystem Filesystem kbytes used avail %used Mounted on /dev/ MyVG /lvol1 573440000 533892407 37080557 94% /filesystem
The actual size is 573440000 Kb (573 Gb) and you will increase it to 574440000 Kb (574 Gb).

- Check if there is available space in the Volume Group:
# vgdisplay MyVG --- Volume groups --- VG Name /dev/MyVG VG Write Access read/write VG Status available Max LV 255 Cur LV 1 Open LV 1 Max PV 100 Cur PV 17 Act PV 17 Max PE per PV 15000 VGDA 34 PE Size (Mbytes) 16 Total PE 36907 Alloc PE 35000 Free PE 1907 Total PVG 1 Total Spare PVs 0 Total Spare PVs in use 0

Note the “Free PE” and “PE Size (Mbytes)”. It say that you has 30512 Mb (30Gb) available in MyVG (Free PE * PE Size).

- Increase the lvol:
# lvextend -L 574440 /dev/MyVG/lvol1 * the syntax is: lvexten -L

- Now, increase the filesystem:
# fsadm -b 574440m /filesystem * the syntax is: fsadm –b

To change the hostname in HP-UX:

- Edit the file "/etc/rc.config.d/netconf"
# /etc/rc.config.d/netconf
- Look for the line that starts with HOSTNAME and change the hostname, example:
HOSTNAME="mylittleserver"
- Now, apply the change:
# /sbin/init.d/hostname start

To use the buttons at the bottom of the glance, you should do an "export TERM=dtterm".

After that, you will be able to use:
F1 for ProcList F2 for CPU Rpt F3 for Mem Rpt F4 for Disk Rpt F5 for NextKeys F6 for SlctProc F7 for Help F8 for Exit
