Check the HMC address on the small machine:
1. First adjust to 02 and change N to M
2. Adjust to 30 again, select 3000 to view the HMC1 address, 3001 to view the HMC2 address
3. After finishing, adjust to 02, change M to N, and restore to 01 mode

If the hard disk is recognized, if there is no PVID, execute the following command
chdev -l hdiskn -a pv=yes
Create VG -s PP size 1024MB -t can add 2 PVs -y vg name -f force add hdisk hard disk name
mkvg -s 1024 -t 2 -y datavg -f hdisk1
Then activate the volume group
Clear pvid
chdev -l hdisk7 -a pv=clear
#rmdev -dl hdisk(x) delete, -d means completely remove from ODM library
After the hard disk is deleted, if you want to use it again, you need to use cfgmgr to re-identify or restart it, such as using the cfgmgr command to identify
#cfgmgr -v
Create LV command:
mklv -y softlv -t jfs2 rootvg 15G
mklv -y datalv -t jfs2 datavg 5G

mkdir soft
mkdir data01
Create file system command:
crfs -v jfs2 -d /dev/softlv -m /soft -A yes
crfs -v jfs2 -d /dev/datalv -m /data01 -A yes
Mount the file system:
mount /soft
mount /data01
AIX network card binding and aggregation specific steps
The configuration method (link aggregation or link redundancy) in which two network cards en0 and en1 in aix system share one IP address.
What you want to achieve: Bind two network cards into a virtual network card, when one network card fails or a switch stops, it will not cause network interruption.
Methods as below:
If the existing network card already has an IP address, first delete the network card configuration information:
#ifconfig en0 down
#ifconfig en0 detach
#rmdev -dl en0
#rmdev -dl et0
#rmdev -dl ent0
Do the above five steps to 1 again (that is, replace 0 with 1)
2. Re-identify the two network cards:
#cfgmgr -v
3. Network card binding:
#smitty etherchannel ->Add An EtherChannel / Link Aggregation, select ent0, press enter, select ent1 in the "Backup Adapter" position, press enter to execute.
The system will generate ent4 (because your system already has four network cards ent0~ent3)
4. Configure ip address and subnet mask for en4:
#smitty chinet
(If en4 is not in the selection list, please execute smitty inet->Add a Network Interface->Add a Standard Ethernet Network Interface)
5. If necessary, you can also perform step 5 to add a default route:
#smitty route ->Add a Static Route -> "DESTINATION Address" write 0, "Default GATEWAY Address" write the default gateway address, press Enter to execute.

Query installed packages:
lslpp -l | grep -i java6
Check the OS version, and patch information
oslevel can return the main version and ML patch information
#oslevel -r
Query the current latest package:
oslevel -s

Include corresponding LANGUAGE filesets? yes
DETAILED output? no
Process multiple volumes? yes
ACCEPT new license agreements? no
Preview new LICENSE agreements? no
among them
PREVIEW only means preview installation, if you choose yes, you can test the installation first
COMMIT software updates means submit immediately. If yes is selected, SAVE replaced files is no.
ACCEPT new license agreements is generally selected as yes, which means that the license agreement is accepted.
After confirming, press Enter to start the installation.
2. Install the patch
#smit update_by_fix
Select the installation directory, such as
INPUT device / directory for software [/dev/cd0]
Open the installation list and select the patch to be installed, such as
