NPIV

Presenting storage to LPARs for SAN boot using NPIV is a 2 step process.

First you need to boot the LPAR using nim to make FC adapters appear at switch level.

You can confirm same using Ports logged in in lsmap output.

Name Physloc ClntID ClntName ClntOS

------------- ---------------------------------- ------ -------------- -------

vfchost2 U8233.E8B.1032F3P-V1-C15 5 mqwuat1 AIX

Status:LOGGED_IN

FC name:fcs0 FC loc code:U5877.001.00H2594-P1-C2-T1

Ports logged in:1

Flags:a

VFC client name:fcs0 VFC client DRC:U8233.E8B.1032F3P-V5-C15-T1

Once you zone at switch you need to reboot lpar using nim again

to make WWN appear at storage side.

Verify your mksysb.

I couldn't create a NIM SPOT using mksysb image.

When I have verified, I figured out that my mksysb image was not clean/complete.

1)lsmksysb -lf /export/mksysb/mksysb_20110210_14.wasprod1

clean with out any errors

Shows system,OS info and filesystems info

2) restore -Tqvf /export/mksysb/mksysb_20110210_14.wasprod1 >/dev/null

New volume on /export/mksysb/mksysb_20110210_14.wasprod1:

Cluster size is 51200 bytes (100 blocks).

The volume number is 1.

The backup date is: Thu Feb 10 09:10:02 CST 2011

Files are backed up by name.

The user is root.

Mount volume 2 on /export/mksysb/mksysb_20110210_14.wasprod1.

Press the Enter key to continue.

Volume 2 .... never seen this error

Solution

Lets recreate mksysb again :)

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"

ClusterSNum = ""

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

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

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

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