To install a VIOS with NIM, you have to use the installation CD of the VIOS

• After the LUN creation on DS8000, and map to VIOS (minimum 2)
• On the first VIOS as padmin (ex: vios1)

[padmin@vios1]/home/padmin# cfgdev

• The new LUN is discover
• Affect a PVID (usefull, because it's easier to find a LUN on multiple server: vios1, vios2, and target LPAR)

[padmin@vios1]/home/padmin# chdev -dev hdisk15 -attr pv=yes

• On the second VIOS as padmin (ex: vios2)

[padmin@vios2]/home/padmin# cfgdev

• Now map the new LUN on both VIOS

[padmin@vios1]/home/padmin# mkvdev -dev hdisk15 -vadapter vhost5 -dev labotest_b1
[padmin@vios2]/home/padmin# mkvdev -dev hdisk15 -vadapter vhost5 -dev labotest_b1

• On the target LPAR:

[root@labotest]/root # cfgmgr

Now the new LUN is available, you can balance IO between the 2 VIOS.
