Virtual DVD - Complete Steps

1) Convert the mksysb image to a bootable dvd using mkdvd command
2) Create a virtual media repository in VIO server
3) Copy/SCP/FTP the dvd file to vio server and add the dvd image into the repository
4) Create a Virtual DVD and load the images
5) Assign that optical device to the new LPAR
6) Make the optical device as first boot
7) Start OS install

From any LPAR,... (having mksysb)... make sure / FS (root FS) has atleast 1.5 times the size of mksysb

$ lsrep
The DVD repository has not been created yet.

$ lsvg rootvg

we will use rootvg to create the repository, as it has lot of space

$ /usr/sbin/mklv -y'aixdvd' -t'jfs2' rootvg 24

first we need to create LV in whichever vg

>>> Choice [1]:

Installation will Start...., After 46% of installation it will ask for 2nd DVD.... Since we have 2 images..

Like >    Please remove volume 1, insert volume 2, and press the ENTER key.

Go to VIO server:
============

$ unloadopt -vtd vtopt0

$ loadopt -disk cd_image_9764974.vol2 -vtd vtopt0

After loading, Check the same in lsmap output..

Go back to Installation screen and hit Enter..

After installtion gets completed, server will be rebooted automatically by setting hdisk as first boot device...

you can login as your id... or if you know the root passwd for the mksysb.

If root passwd is not available, unload the second DVD and put the first DVD.... then go to maintancence mode and reset the passwd.

$ unloadopt -vtd vtopt0

$ loadopt -disk cd_image_9764974.vol1 -vtd vtopt0

Go to HMC session... as hscroot

$ chsysstate -r lpar -m P59XXD1_SNXXXXB4 -n Client1 -o on -f Client1_normal -b sms

Change the boot order.... set the CD as 1st boot device and continue with installation.. choose 3 for "system maintanence and recovery"

There you can reset the root passwd.

To list the filesets inside .bff

IBM filesets are typically in the .bff format, which can be downloaded from IBM Fix Central.
To check which filesets are included in a specific .bff package, use the following command:

# bffcreate -ld U829647.bff
Package Name Level I/U Content
------------------------------------------------------------------------------
perl.libext 2.2.6.0 U usr

I --> Installable Fileset (base package will be included)
U -> upgrade filesets

How To identify the Stale PP numbers

The lslv -p command displays how a Logical Volume (LV) — in this case oraclelv — is physically allocated across a given Physical Volume (PV), here hdisk0.

So it shows which physical partitions (PPs) on the disk are used or free for that LV.

lslv -p <PhysicalVolume> <LogicalVolume>

PhysicalVolume (hdisk0) → the actual disk device.

LogicalVolume (oraclelv) → the logical volume you want to inspect.

Field	Meaning
USED	Partition currently used by the logical volume (contains data).
FREE	Partition available for use (not yet allocated).
Numbers (0001, 0002, etc.)	These show Logical Partitions (LPs) within the logical volume — the mapping between physical and logical partitions.
Range (e.g., 1–10, 219–228)	Shows the PP numbers on the disk (each disk is divided into a number of PPs).

server1:/root # perl -le 'print scalar localtime 1332327025'
Wed Mar 21 03:50:25 2012

Note:
You can verify the same timestamp using the last | grep sankar command.
However, if the user hasn’t logged into the server for several years, the last command might not display any information — because the login history is retained only for a few months and is rotated periodically.

NFS port ranges

Normally, NFS ports in AIX are assigned dynamically.
If you want to define a specific range of ports, you can use the NFS_PORT_RANGE environment variable to restrict the source ports used by the NFS client when connecting to the server.

Add the variable to the /etc/environment file in the following format:

NFS_PORT_RANGE=udp[4000-5000]:tcp[7000-8000]

OR

Server2:/ # nfso -a | grep port
portcheck = 0
nfs_use_reserved_ports = 0

Explanation:

When nfs_use_reserved_ports=0 → The AIX server uses non-reserved ports (above 1024) for NFS client communication.
When nfs_use_reserved_ports=1 → The AIX server uses reserved ports (below 1024) for NFS client communication.

Data transfer speed is slow from server1 to server2

The data transfer between server1 and server2 involves file copying over the network using TCP/IP via Ethernet.
There are no SAN or external storage devices involved in this process, so the storage team’s assistance is limited.

To improve transfer speed, consider using the backup LAN, provided both systems are on the same VLAN — this can significantly enhance throughput.
Use the hostnames server1b and server2b for data transfer, where “b” refers to the backup LAN interface.

Alternatively, you can mount the file system of server1 as read-only on server2 over the backup LAN (depending on accessibility) and then start copying the data directly.

rsync

Just an example: from server1 to server2

rsync -avz -e ssh root@server2:/opt/softwaredepot/* /opt/softwaredepot_new/

need to run this from server1. We are pulling from server2

Before that, we need to set ssh keyless access from server1 to server2

===========================

If you have ssh in place for root..from server3 to server4

So from server3 (push method)

rsync -avz /xxxxxxxx/yyyyyyy/* root@server4:/xxxxxxxx/yyyyyyy/

Procedure to clean up the HMC filesystems

As a hscroot check the filesystem use

monhmc -r disk -n 0

- Free up space in /var

chhmcfs -o f -d 0


- As hscpe, login to HMC and use pesh to exit restricted shell then su to root

- As root run following commands

cd /opt/ccfw/data/vr

chsvcevent -o closeall

rm -rf [123456789]*

reboot

Prework before Physical processor book - Memory DIMM addition

Add the physical CPU processor book to the frame.
Add the memory DIMMs to the frame.
Add the I/O cards as required.

Before performing these hardware additions, make sure to capture screenshots of the frame properties, specifically the Memory, Processor, and I/O tabs.
These screenshots will help record the Installed / Available / Configured / Deconfigured values.

Once the new CPU and memory modules are added, the frame will display only the updated values, and the previous configuration details will no longer be visible — hence, it’s important to capture this information in advance.

Alternatively, you can run the following command on any LPAR to capture the hardware details of the entire frame:

# lscfg -vp

As a standard practice, also run the prework.sh script on all LPARs before shutting down the frame.

Portmir

portmir (short for Port Mirror) is an AIX utility that allows you to monitor, share, or take over another user’s terminal session on the same system.

The tty command shows which terminal (pseudo-terminal or TTY device) you are currently connected to.
Here, your terminal is /dev/pts/8.

# tty
/dev/pts/8

You can use the who command to see all users currently logged into the server along with their terminal numbers.
For instance, if the oracle user is connected through pts/9, you can monitor their terminal session remotely using:

# portmir -t /dev/pts/9

To disconnect the session
# portmir -o /dev/pts/9

Save your file with passwd protected.

server1:/tmp # touch testenc

server1:/tmp # echo "hi I am a line" > testenc

server1:/tmp # cat testenc
hi I am a line

server1:/tmp # openssl bf -salt -in ./testenc > ./testenc1
enter bf-cbc encryption password:
Verifying - enter bf-cbc encryption password:

server1:/tmp # cat testenc1
Salted__°îøÐýÉÉQÝly¶ïÑ^±oþjõserver1:/tmp #

server1:/tmp # openssl bf -d -in ./testenc1 >./testenc
enter bf-cbc decryption password:

Paging utilization - Tricks

If the paging space utilization remains consistently high (for example, above normal levels) for more than 3 days, you can use the following method to reduce it.

Check Current Paging Utilization

server1:/root # lsps -s

Total Paging Space Percent Used

21312MB 28%

Reduce Paging Utilization

Run the following command to decrease the paging space by 1 physical partition (PP):

server1:/root # chps -d 1 paging00

This command will:

Create a temporary paging space (paging01)
Move data or reduce usage from the existing paging space
Recreate the original paging space (paging00) with a smaller size

⚠️ Important:
This process temporarily doubles the required paging space (≈28% × 2).
If there isn’t enough free disk space to accommodate this, do not run the command.

🔹 Explanation

By reducing 1 PP:

A temporary paging space is created
Data is moved or swapped
Utilization drops to around 1–2%

After utilization decreases, you can add the partition back:
server1:/root # chps -s 1 paging00

Then verify again:


server1:/root # lsps -s
Total Paging Space   Percent Used
      21376MB               1%

⚠️ Note
Never attempt this method if your paging space usage exceeds 50%, as it may cause system instability or paging failures.

Paging and Sysdump - Redundancy checks
