aix : reconfig disk from direct attached to san attached fastt?? 2

[kat115]

Hi,
Today I have two AIX servers directly attached to a fastt600.
I'm going to add a new aix server, and install 2 switches to access the storage (SAN attachement).
I don't know how to do to reconfigure the disks for the currently used server?
Should I exportvg, then rmdev hdisks, then importvg ???
Or is there another way?

Thanks for your help !!

You will need to do the following:

exportvg
rmdev the hdisks
shutdown host
plugin hosts and Fastt600 to switch
setup Lun Security
power on host
zone each host to the Fastt ports
cfgmgr
importvg of disk

hi,
Thanks a lot for your answer.
Can you explain what you mean by "setup LUN security"?
Thank you very much

LUN Security is LUN Masking or Storage Partitions with Storage Mangager.

LUN Security is used to secure a LUN to a host. Without it all hosts will see all LUNs from Storage Port he is assigned.
