Audit file has 0% free space left ! Unable to Login through root and also unable to login through console.There is at time when login into the HP-UX system is the problem. We get the problem statement something like:
Error Flashed: Current audit file size is 613959 kilobytes!!! an attempt to switch to the backup file failed.
Must specify a backup file now ! audit file has 0% free space left !
Solution:
Step -1 Login HP-UX in single user mode.
1. shutdown -r 0
2. hit during 10 sec window to interrupt reboot
3. enter:
4. interact with ipl? yes
5. hpux -is (i=init, s=single user)
Step -2 Mount the all files system in single usermode
#mountall
Step -3 Check the root file system.
# bdf /
Step -4 Audit data written into a logfile in your root filesystem (usually into /.secure/etc)
Go to ./secure/etc Directory
# cd ./secure/etc
Step -5 Delete the audfile1 and audfile2
# cd ./secure/etc
# rm –rf audfile1
# rm –rf audfile2
Step -6 Reboot the server and boot in normal mode.
Thats it .........

Network Configuration tools on HP-UX.
This post is about the location of various files used in network configurations in HP Unix Servers.
FILE:
/etc/hosts - Hosts configuration file (resolve hosts and IPs)
/etc/rc.config.d/ netconf – IP address, routing address and hostname stored in this file.
SCRIPTS:
/etc/init.d/net start – Use to start, stop network service
HP UX Commands
(a) Display lan interface info:
FILE:
/etc/hosts - Hosts configuration file (resolve hosts and IPs)
/etc/rc.config.d/ netconf – IP address, routing address and hostname stored in this file.
SCRIPTS:
/etc/init.d/net start – Use to start, stop network service
HP UX Commands
(a) Display lan interface info:
# lanscan
(b) All in one lan configuration utility (lan0 is first Ethernet interface) to configure and view the system IP address:
# ifconfig lan0 - Display IP info such as IP address netmask etc.
# ifconfig lan0 up - Up network interface (allow traffic)
# ifconfig lan0 down - Down network interactive (deny traffc)
# ifconfig lan0 192.168.1.1 netmask 255.255.255.0 up - Setup/change IP adddress
# netstat –in
(c) Displaying host name
# hostname
(d) Arp administration (cache)
# arp -a
(e) Display routing table/info:
# netstat –nr
(f) Define new route:

The disk management is the important part of any system.
Lets see how this task is performed on the HP-Unix system.
HP-UX: Disk Management
Here are the steps to follow:
1- Open the prompt.
2- ioscan -fnC disk = Search Attach disk with HP server
3- pvcreate -f /dev/rdsk/c0t1d0 = Initialize a disk for use with LVM
4- Create the device structure needed for a new volume group.
cd /dev
mkdir vgdata
cd vgdata
mknod group c 64 0x010000
5- vgcreate vgdata /dev/dsk/c0t1d0 = Create volume group vgdata
Note: if your expecting to use more than 16 physical disks use the -p option, range from 1 to 256 disks.
6- vgdisplay -v vgdata = Display volume group vgdata
7- pvcreate -f /dev/rdsk/c0t4d0 = Add another disk to volume group
vgextend vgdata /dev/dsk/c0t4d0
8- vgreduce vgdata /dev/dsk/c0t4d0 = Remove disk from volume group
