Subject: [PATCH] ieee1275: implement FCP methods for WWPN and LUNs
|
|
|
|
This patch enables the fcp-targets and fcp-luns methods which are
|
|
responsible to get WWPNs and LUNs for fibre channel devices.
|
|
|
|
Those methods are specially necessary if the boot directory and grub
|
|
installation are in different FCP disks, allowing the dev_iterate()
|
|
to find the WWPNs and LUNs when called by searchfs.uuid tool.
|
|
