Add new LUN in AIX
Hello all!
I have not so much experience with AIX
We have test p5 server. On server was deployed VIOS + 3 LPAR + AIX6.1
There is a test HACMP cluster of two nodes, the cluster is identical to production cluster (all clusters and hosts have been configured by specialist of integrator company and the previous admin)
In the cluster resource group, there is one LUN, which was mapped from storage - DS3524
The task - to add a new LUN on AIX, and then add it to the resource group.
I create new ​​LUN - 400GB on the DS3524
Next I successfully mapped new LUN to LPAR, by using datastore manager console, because WWN is already registered on Datastorage, i though that AIX should be able to see new LUN
In VIOS I have not changed anything. Thoughts aloud - as I understand VIOS present resources LAN,IO,CPU etc. to LPAR? Сorrect me if I'm wrong
However mapping new LUN on AIX does not work
I can not create a volume group, an error citing the lack of drive in the system:
Although i think that OS able to see new LUN, according to the findings of the command - lsdev -Cc disk
Actually that's the results themselves commands

The output of lspv:
Code:
hdisk0 0003f6e5091283af None
hdisk1 0003f6e5c74dae18 oravg concurrent
hdisk2 0003f6e5402bbc38 None

Could you give some recomendations for solve this porblem, or some give some guide
Thanks in advance!

Recommendation 1. If you speak Russian, welcome to aixportal.ru.
Recommendation 2.
Code:
rmdev -Rdl hdisk8

Recommendation 3.
Code:
cfgmgr

and output in this topic together with lsdev before and after cfgmgr
Recommendation 4.
Code:
lscfg -vl fcs* | grep -E 'Adapter|Address'

on AIX and check what you see on your storage
Recommendation 5. I've never worked with DS3K, but on "normal" storages you have to specify the right OS type. In most cases - AIX, sometimes special HACMP to tell the storage that it has to work with the cluster.
