Which HMC is controlling my LPAR?

To figure out which HMC is controlling a particular LPAR.

Login to a LPAR and use either of commads

$ /usr/sbin/rsct/bin/rmcdomainstatus -s ctrmc

I a 0x3b7a655c73b1d930 0001 XX.XX.XX.XX ( Where XX.XX.XX.XX is the IP address of HMC).

or

$lsrsrc IBM.ManagementServer

Resource Persistent Attributes for IBM.ManagementServer

resource 1:

Name = 'XX.XX.XX.XX"

Hostname = "XX.XX.XX.XX"

ManagerType = "HMC"

LocalHostname = "lparname"

ClusterTM = "9078-160"

ClusterSNum = ""

ActivePeerDomain = ""

Trace on VIO commands.

VIO command shell is a restricted shell(like HMC shell). If anybody wondering what AIX commands will be executed beneath VIO commands?

Here is the answer

example:

$ export CLI_DEBUG=33

$ lsmap -all

AIX: "lsdev -c adapter -t IBM,v-scsi-host -s vdevice -F "name" | wc -l -c"

AIX: "lsdev -c adapter -t IBM,v-scsi-host -s vdevice -F "name""

AIX: "lsdev -C -l vhost0 -F "physloc""

AIX: "lsdev -p vhost0 -F "name" | wc -l -c"

AIX: "lsdev -p vhost0 -F "name""

AIX: "lsattr -E -l vtscsi0 -F "value" -a aix_tdev,LogicalUnitAddr"

SVSA Physloc Client

-

$ export CLI_DEBUG=33

$ mirrorios -f hdisk1

AIX: "lsvg -p rootvg"

AIX: "lsvg -p rootvg | awk '{print $1}' | wc -l -c"

AIX: "lsvg -p rootvg | awk '{print $1}'"

AIX: "lsvg -l rootvg "

AIX: "lsvg -l rootvg | grep boot | awk '{print $1}'"

AIX: "lsvg -M rootvg "

AIX: "lsvg -M rootvg | grep hd5 | awk '{print $2}' | awk '{FS=":"}{print $3}'"

AIX: "mirrorvg -c 2 rootvg hdisk1 "

sockinfo -find out which process holds given socket port

AIX Only
# cat /usr/bin/sockinfo
#!/bin/ksh
netstat -Aan | grep "*.$1" | read s1 t1 t2 t3 t4
echo "Socket Address=>$s1"
echo "sockinfo $s1 tcpcb " | kdb | grep "^pvproc" | read pvproc procname active hex1 hex2 rest
echo "Socket occupied by PID=>" $((16#$hex1))

EX:
# sockinfo 8080
Socket Address=>f100020001c64398
Socket occupied by PID=> 258154


or you can use lsof ( Generic AIX/Linux etc best)

Ex: lsof -i :8080
lsof: WARNING: compiled for AIX version 5.1.0.0; this is 5.3.0.0.
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 258154 root 76u IPv6 0xf100020001c64398 0t0 TCP *:http-alt (LISTEN)

or
# rmsock f100020001c64398 tcpcb (AIX only)
The socket 0x1c64008 is being held by proccess 258154 (java).

Disable Ping on AIX & Linux

Disable Ping on AIX & Linux


I had to disable ping for security concerns. Basically I hid my system from ICMP echo discovery.


on AIX

/usr/sbin/genfilt -v 4  -a 'D' -s '0.0.0.0' -m '0.0.0.0' -d '0.0.0.0' -M '0.0.0.0' -g 'y' -c 'icmp' -o 'any' -p '0' -O 'any' -P '0' -r 'B' -w 'B' -l 'N' -t '0' -i 'all' -D 'echo_request'


Easy way is use smitty ipsec4 ,fill required fields.

don't forget to start

smitty ips4_start


on Linux

echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all (on fly and temporary)



add/comment out  net.ipv4.icmp_echo_ignore_all=1 in /etc/sysctl.conf
