We have exactly same setup so I thought I could share simple scripts I
use for automation. You can run it by executing ./script.sh lun_number
(script bellow)
XIV uses lun numbers is decimal, and zfcp scripts in linux use hex
numbers. Script does dec - hex conversion so you can provide a lun
We have an XIV connected to 2 switches which in turn is connected to our
z10 through 4 adapters.
We have defined 5 luns for use under SLES11SP2.
Right now, we are using YaST to define all of the connections. This
seems to be cumbersome.
Is there a way for us to to scan and define each lun
Certainly. There are ways in both Linux and CMS. I often do this in CMS
by attaching the FCP device and running SCSIDISC.

If you know the LUNS and (especially) the storage WWPNs then set things up using
/sbin/zfcp_host_configure
and
/sbin/zfcp_disk_configure
If the SAN volumes must be online early then you'll need to re-cut
your initial RAM disk with 'mkinitrd' after defining the
