Test Description
In boot-from-SAN environments, the fiber-channel driver attributes and multipath configuration need to reside inside the initrd image.
This test case checks it is necessary to re-create the initrd image, and creates one if necessary
This test case fails if:
The server boots from a fiber-channel disk and if infinihost changes fc driver attributes or multipath settings since the last reboot
This test case passes if:
There is no need to re-generate the initrd
How to fix this test
Automatic fix
The automatic fix performs the following steps:

initrdimage file - Overrides the existing
initrdimage file by runningmkinitrd - Creates a backup copy of
/etc/grub.conf - Puts a backup entry inside
/etc/grub.confthat loads the backup copy ofinitrd
Manual fix
