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.

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 :)
