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:

  1. Writes the recommended options to the configuration file
  2. Creates a backup copy of the initrd image file
  3. Overrides the existing initrd image file by running mkinitrd
  4. Creates a backup copy of /etc/grub.conf
  5. Puts a backup entry inside /etc/grub.conf that loads the backup copy of initrd


Manual fix

To create a new initial ramdisk image:

  • For Redhat 6 or 7: 

    dracut -f /boot/initramfs-`uname -r`
  • For Redhat 5: 

    mkinitrd -f /boot/initrd-`uname -r` `uname -r`

Applies to

  • Linux
