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

Note : Images Splitted into 2 DVD's

VIO part:

$ 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

$ lsvg -lv rootvg

>>> 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.

- Right click on the partition

- Select 'Properties'

To find the server reboot time, from HMC event log....

hscroot@hmc2:~> date

Note:
1) 03/26/2012 03:39:49 rebooted via HMC command
2) 03/26/2012 04:05:56 rebooted via HMC GUI

To check the last login time, using perl

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

Note : You can check the same in "last | grep sankar"..... But, if the user didnt login to the server for years time... then you may not get the info from "last" command... Because, last log will keep the info for few months and it will rotate...

NFS port ranges

Normally, The usage of NFS ports will be dynamically in AIX.... If you would like to set the port ranges,

The NFS_PORT_RANGE environment variable can be used to limit the source port of network calls the client makes to the server.
If used, this environment variable should be added to the /etc/environment file. The format of the environment variable is as follows:

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

OR

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

If nfs_use_reserved_ports=0 AIX server uses nonreserved IP port numbers above 1024 when the NFS client communicates with the NFS server.
If nfs_use_reserved_ports=1 AIX server uses nonreserved IP port numbers below 1024 when the NFS client communicates with the NFS server.

Oracle memory - Actual usage

Oracle memory actual usage

find oracle instances --> ps -ef | grep ora_smon
svmon -P $( ps -elf | grep ora_smon_ORDID | grep -v grep | awk '{print $4}' |) | grep shmart
check for 6th and 7th field. s means 4KB blocks m=64KB L=16MB blocks
more details @

To find expected usage
to get sysresv output
su - oracle
export ORACLE_SID=<ID got from ps -ef | grep ora_smon>
sysresv
ipcs -ma | grep (oracle shared memory instance ID got from sysresv command in sql prompt)

Data transfer speed is slow from server1 to server2

Purely files (host application, using TCP IP over Ethernet) copying over network from server1 to server2, there is no SAN or storage device involved in this data transfer.... So, storage team cannot help much on this.

One thing which can makes difference is you can use backup LAN if they are in same VLAN. Which can definitely speedup data transfer.

Use the server1b and server2b as host names to transfer data.
b-> backup LAN

One more option.. mount the file system of server1 as readonly on server2 over backup LAN based on accessibility & start data copy

Script - xargs for changing Filesystem to auto mount

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

1. Physical CPU processor book add in the Frame

2. Memory DIMM add in the frame

3. I/O cards add

For the above tasks, make sure to take the screen shot of FRAME properties like.......

Memory, processor and I/O tabs.... So that you can will have the details of "Installed / Available / Configured / De-configured" parameters.
After adding the physical CPU, Memory in the Frame.., you can able to see only the NEW parameters in the Frame. You will not get the old "Installed / Available / Configured / De-configured" parameters.
So, make sure to take the screen shot......

OR

you need to take the output of #lscfg -vp in anyone of the LPARS, that will tell us the physical devices connected in the Entire frame.

Also, as usual run the prework.sh in all LPARS, before shutting down the FRAME.

Portmir

portmir

# tty
/dev/pts/8

To take session
# portmir -t /dev/pts/8

To disconnect the session
# portmir -o /dev/pts/8

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:

Paging utilization - Tricks

If the paging utilization is sudden high and keeping constant in that place for more than 3 days... then use this method to reduce the paging utilization.

server1:/root # lsps -s
Total Paging Space   Percent Used
      21312MB               28%

server1:/root # chps -d 1 paging00
shrinkps: Temporary paging space paging01 created.
shrinkps: Paging space paging00 removed.
shrinkps: Paging space paging00 recreated with new size.

(THIS COMMAND WILL TAKE DOUBLE SIZE OF PAGING, THAT IS 28X2 TIMES) IF YOU DO NOT HAVE ENOUGH SPACE IN PAGING... DONT RUN THIS COMMAND.

by decrease 1 pp.....it will create temp paging ... move or reduce usage then recreate
so at end % will become 1 or 2%
will decrease 1 pp and later add it back after % is reduced

now add back the 1 pp

server1:/root # chps -s 1 paging00

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

NOTE : Never try this steps, when your paging is more than 50%

Paging and Sysdump - Redundancy checks
