IBM AIX
AIX,是IBM專有UNIX作業系統的商標名。名稱來自先進互動執行系統(英語:Advanced Interactive executive,縮寫為)。最初的名稱來自英語:Advanced IBM Unix,但或許這個名字沒有得到法律部門的允許,因此更改為"Advanced Interactive eXecutive"。

Migrate System Accounts to another Server
Cloning AIX users and groups between servers
# one-liner to generate the commands to clone groups
lsgroup -c -a id ALL | grep -v ^# | awk -F: '{print "mkgroup id=" $2, $1}'
# one-liner to generate the commnads to clone users
lsuser -c -a id pgrp groups home shell gecos ALL | grep -v ^# | awk -F: '{print "useradd -m -u", $2, "-g", $3, "-G", $4, "-c \"" $7 "\" -d ", $5, $1}'
Copying AIX password hashes between servers
# grep -p root /etc/security/passwd
root:
password = 2zfymAdUyNdA.
lastupdate = 1360555127
echo 'root:2zfymAdUyNdA.' | chpasswd -ec
gen_reset_password.sh:
#!/usr/bin/ksh
for user in `lsuser -a ALL`; do
[ -n "$1" -a "$user" != "$1" ] && continue
if grep -p ^${user}: /etc/security/passwd | grep -q "password = "; then
hash=`grep -p ^${user}: /etc/security/passwd | grep "password = " | awk -F " = " '{print $2}'`
echo "echo '${user}:${hash}' | chpasswd -ec"
fi
done
# ./gen_reset_password.sh
echo 'root:2zfymAdUyNdA.' | chpasswd -ec
echo 'daemon:*' | chpasswd -ec
echo 'bin:*' | chpasswd -ec
echo 'sys:*' | chpasswd -ec

AIX 管理技巧
Install package lsof
Where to download the lsof, bind, rsyslog, openssh, openssl, etc packages?
lsof_4.892.tar
tar xf lsof_4.892.tar
cd lsof_4.892
installp -acgXYd . lsof.base lsof.license lsof.man.en_US
lsof -v
tar xf lsof_4.892.tar
cd lsof_4.892
smitty installp
# Install Software
# INPUT device / directory for software [.] << Input a dot
# SOFTWARE to install [_all_latest] << Esc + 4, Esc + 7
# ACCEPT new license agreements? yes
User & Group
# Create a new user
mkuser admin="false" pgrp="staff" gecos="Test User" test3
mkuser admin="false" pgrp="staff" groups="sshusers" gecos="Test User" test3
# Remove a user
rmuser -p <user-name>
Network
Check the interface
lsdev -Cc if
lsdev -Cc adapter
lscfg -vpl ent0
lsattr -El ent0
lsattr -El en0
Configure the network
# Set the ip/netmask/gateway
/usr/sbin/mktcpip -h'aixvm' -a'192.168.99.100' -m'255.255.255.0' -i'en0' -g'192.168.99.1' -A'no' -t'N/A'
# Set the DNS server addr
echo "nameserver 1.1.1.1" > /etc/resolv.conf
Check the port opened
netstat -Aan
資安相關指令
# Login Failed
who /etc/security/failedlogin | tail -50
# Check the number of previous unsucessful logins for the account to confirm it is blocked
lsuser -a account_locked unsuccessful_login_count {ALL|user_name}
# To check with particular user’s last password changed
pwdadm -q {user_name}
lssec -f /etc/security/passwd -a lastupdate -s {user_name}
lsuser -a lastupdate {user_name}
## Convert the EPOCH-TIME
perl -le 'print scalar localtime $ARGV[0]' {epochtime}
# Reset unsucessful login counter
chsec -f /etc/security/lastlog -a unsuccessful_login_count=0 -s {user_name}
# Unlock the locked account
chuser account_locked=false {user_name}
# Lock account
chuser account_locked=true {user_name}
# List the locked accounts
lsuser ALL | sed -n '/account_locked=true/p' | sed '/sshd/d' | awk '{print $1}'
登入失敗後自動鎖定
- 可指定帳號或全域設定
- 注意:retry 的次數是累計制,登入成功一次,計數不會歸零
- 解鎖方式是歸零登入失敗的計數
chuser loginretries=5 <username>
lsuser -a loginretries <username>
Mount CD-ROM & ISO
# Mount CD-ROM
mount -V cdrfs -o ro /dev/cd0 /mnt
# Mount/Umount ISO file
loopmount -i aix61_dvd.iso -o "-V cdrfs -o ro" -m /mnt
loopumount -l loop0 -m /mnt
解封 HMC root
Restrictd users to switch to root
# Create a group sysadm
mkgroup sysadm
# Add the user1 that is allowed to su to root into the group sysadm
chgrpmem -m + user1 sysadm
lsgroup sysadm
chsec -f /etc/security/user -s root -a sugroups=sysadm
# Reset to the default, sugroups=ALL
# Alternatively
smitty user
# Change / Show Characteristics of a User
# User Name [root]
# SU GROUPS [sysadm]
Restricted Shell
針對指定帳號限制登入後的預設 Shell 環境的執行權限
教學:
Defaul Shell:
# Change the default shell for the user to the restricted shell such as rksh or Rsh.
chuser shell=/usr/bin/rksh <user-name>
# OR
chsh <user-name> /usr/bin/rksh
.profile:
# Add the commands that are allowd to run by the user into the directory.
mkdir /usr/bin/restricted
cd /usr/bin/restricted
ln -s /usr/bin/date date
# Create a .profile in the user's home directory and set the PATH environment variable to
# a directory containing all of the commands you want the user to be able to run
export PATH=/usr/bin/restricted
Core dump
# 解析 core file
dbx -C ./core
(dbx) corefile
(dbx) dump
(dbx) quit
System dump
errpt:
67145A39 0413095315 U S SYSDUMP SYSTEM DUMP
Copy the dump from the dump device to a file using the savecore
command:
savecore .
Yes, the period is necessary. It indicates you want the dump copied to your current directory
savecore will copy the dump to your current directory, and name it:
vmcore.0.BZ
Uncompress the dump using the dmpuncompress command:
dmpuncompress vmcore.0.BZ
Lastly, format the dump:
/usr/lib/ras/dmprtns/dmpfmt -c vmcore.0
Reading a Dump
kdb vmcore.0 vmunix.0

系統效能
實測數據
- AIX 更新: 從 7200-05-06-2320 至 7200-05-08-2420,更新檔約 8 GB,共花費時間 2.5 小時。
- AIX 更新: 從 7200-04-00-0000 至 7200-05-06-2320,更新檔約 7.9GB,總花費時間 5 小時 10 分。
- DB2 Server: 安裝 v11.1 花費 51 分鐘,安裝 FP 7 花費 1.5 小時。
I/O 優化
- AIX 分配 4GB RAM 時,外層 Fedora Linux 建議 12 GB以上 RAM,可避免 Fedora Linux 使用 SWAP memory,以致影響 AIX 的 I/O 效能。
- 如果 Fedora Linux 啟用多個 AIX VMs,Fedora Linux 記憶體配置需要適時地增加。
- 外部電腦要與 AIX 進行檔案交換時,可使用 scp 指令。盡可能不要使用 Fedora Linux 做中繼,因為 Fedora Linux 同時間要執行寫入與讀取,會影響檔案傳輸的效率。
磁區建議最小空間分配
- / : 1GB
- /usr : 5GB
- /var : 1.5GB
- /tmp : 1GB
- /opt : 7GB (For DB2 Server)
遷移現有的 AIX 系統
已知問題
- 執行
lslpp -L
時偶爾會卡住,可以改用-l
取代或重啟 AIX VM 試試。 - 使用 DB2 Server 11.1 時,在安裝 FixPack 與建立 Instance 時會發生錯誤,需要使用 db2chgpath 指令修復。
- 如果 AIX 頻繁增刪檔案,外層的 VM disk hdisk0.qcow2 檔案會不斷增大,即使 AIX 刪除了所有檔案,hdisk0.qcow2 檔案也不會自動縮小。
- 解決方法:關閉 AIX VM,在 Host OS 使用指令
virt-sparsify hdisk0.qcow2 hdisk0-shrink.qcow2
,然後使用 hdisk0-shrink.qcow2 當作 AIX VM disk。
- 解決方法:關閉 AIX VM,在 Host OS 使用指令

AIX VM with virt-manager
技巧
- AIX系統的虛擬磁碟 hdisk0 ,裝置類型必須是 SCSI 磁碟,並且使用指令先建立
qemu-img create -f qcow2 hdisk0.qcow2 20G
,磁碟大小可自行調整。 - 修改 xml 檔時,可以在 virt-manager 介面上操作,或者以指令模式替代。指令是
virsh edit <vm-name>
。
XML
- 修改 iso 檔路徑
- XML 檔增加第一行

Pre-Checks
1.System Backup
備份 VG: rootvg 至其他未使用的 PV,PV 空間需相等或足夠 rootvg 的使用。
# 複製 VG: rootvg 至 hdisk1, 請確認 hdisk1 無重要資料
alt_disk_copy -B -d hdisk1
NOTE: 如果 VG: rootvg 有兩個 PV 做 Mirror,須改用以下指令:
# 複製 rootvg 至 hdisk6
mkszfile
sed 's/COPIES= [2-3]/COPIES= 1/g' /image.data > /image.data.one_copy
nohup alt_disk_copy -B -i /image.data.one_copy -d hdisk6 > clonelog.log &
Optional: 如果目的 PV 曾經做過備份,執行以下指令先做 VG 卸載
exportvg hdisk6
2.Boot Image Verification
檢查目前開機磁碟位置: hd5 是預設開機磁區
root@aixvm:> lslv -m hd5
hd5:N/A
LP PP1 PV1 PP2 PV2 PP3 PV3
0001 0001 hdisk0
3.Firmware
It is recommended to check and update the firmware level when a technology level update is being considered. In general, it's best to apply firmware updates before software updates, but that is not always the case.
4.Fileset Consistency
Ideally, it returns to the command line with no output. If you receive output and are unfamiliar with how to resolve it, call the support center for assistance before running your update.

FAQ
EFIX MANAGER LOCKS
EFIX MANAGER LOCKS
------------------* * * ATTENTION * * *
The following selected filesets are locked by EFIX manager:
bos.rte.control
installp has halted this operation because one or more files in the
filesets listed above are registered as having an EFIX. You must remove
these EFIXES before performing operations on the given fileset.To get a listing of all locked filesets and the locking EFIX label,
execute the following command:# /usr/sbin/emgr -P
To remove the given EFIX, execute the following command:
# /usr/sbin/emgr -r -L <EFIX label>
For more information on EFIX management please see the emgr man page
and documentation.
Solution:
# List the EFIX installed
emgr -l
# List the EFIX locked
emgr -P
# Remove the EFIX locked
emgr -r -L <EFIX lapel>

常用技巧
檢視 非AIX Toolbox 的套件
為了維護套件的相依性與可更新,不要安裝非 AIX Toolbox 包含的其他套件。
執行以下指令,如果輸出 Build Host 不是包含 *.ibm.com 位址的套件,應該考慮將它移除。
Tip: 如果是 AIX-rpm 套件,這是 AIX ISO 預設安裝的,可以忽略它。
rpm -qai | egrep "Name|Install Date|Build Date|Build Host"
Local DNF repository
建立 AIX Toolbox 本地套件庫
步驟:
- 從官網下載最新的 AIX Toolbox ISO 或 TGZ 檔
- 在 AIX 系統掛載 ISO 檔或解開 TGZ 檔,目的路徑:
/mnt/aixtoolbox
- 建立本地庫,執行腳本
/mnt/aixtoolbox/ezinstall/ppc/dnf_aixtoolbox_local.sh
- 檢查設定檔:
/opt/freeware/etc/dnf/dnf.conf
- 執行套件更新
Mount the ISO file
loopmount -i aix_linux_toolbox_*.iso -o "-V udfs -o ro" -m /mnt/iso
Create local repo.
- Usage:
dnf_aixtoolbox_local.sh <mount path or tar extraction path>
/mnt/iso/ezinstall/ppc/dnf_aixtoolbox_local.sh /mnt/iso
自動產生設定檔 /opt/freeware/etc/dnf/dnf.conf :
