</code>

==== Listing Device Files with ioscan ====
<code bash>
# ioscan -fun             --> list all devices, and their associated device files
# ioscan -funC disk       --> only list disk class devices and their device files
# ioscan -funC tape       --> only list tape drives and their device files
# ioscan -funH 2/0/1.6.0  --> only list device files for the device at 2/0/1.6.0
</code>

==== RAW Devices 사이즈 확인방법 ====

==== HP-UX IP Alias ====
  * 설정파일을 수정한다.
<code>
# vi /etc/rc.config.d/netconf
</code>
  * INTERFACE_NAME의 숫자가 중복되어서는 안된다.
<code bash>
INTERFACE_NAME[0]="lan1"
IP_ADDRESS[0]="61.74.73.91"
SUBNET_MASK[0]="255.255.255.128"
BROADCAST_ADDRESS[0]=""
INTERFACE_STATE[0]=""
DHCP_ENABLE[0]=0
INTERFACE_MODULES[0]=""

# 추가한 정보
# 기존에 INTERFACE_NAME[1]이 없어야 한다. 대가로번호가 겹쳐서는 안된다.
INTERFACE_NAME[1]="lan1:1"
IP_ADDRESS[1]="61.74.73.93"
SUBNET_MASK[1]="255.255.255.128"
BROADCAST_ADDRESS[1]=""

</code>
  * 설정파일을 적용한다.
<code>
# /sbin/init.d/net start
</code>
  * (팁) 설정파일을 건드리지 않고, 임시적으로 적용하는 방법
<code>
# ifconfig lan1:3 192.168.200.200 netmask 255.255.255.0 up
</code>

==== HP-UX FileSystem FileSize 제한 확인 ====
<code bash>
soafdb2:/#fsadm -F vxfs /oracle
largefiles
</code>

  * largefiles 가 아니면 파일당 2G로 제한된다.

==== HP-UX OS 백업 ====
  - 백업할 OS 상태를 확인한다.
  - DAT Tape을 넣는다.
  - 아래의 스크립트를 만들어서 돌린다.
<code bash>
# cat /tmp/os_backup.sh                                       
set -x
make_tape_recovery -x inc_entire=vg00

# nohup sh /tmp/os_backup.sh 
</code>

==== HP-UX Product List 뽑아내기 ====
<code bash>
# swlist -l product > /tmp/list.txt
</code>

==== 한글설정 ====
<code>
LANG=ko_KR.utf8
또는 LANG=ko_KR.eucKR
</code>
