HP 3PAR SUSE Linux Enterprise Implementation Guide

Rebuild the ramdisk image using the mkinitrd command, which includes each instance of
the kernel and initrd images, including the default and xen images.
# /sbin/mkinitrd
Example:
# /sbin/mkinitrd
Kernel image: /boot/vmlinuz-2.6.27.19-5-default
Initrd image: /boot/initrd-2.6.27.19-5-default
Root device: /dev/disk/by-id/cciss-3600508b100104a39535533385142000a-part2 (/dev/cciss/c0d0p2) (mounted on / as
ext3)
Resume device: /dev/disk/by-id/cciss-3600508b100104a39535533385142000a-part1 (/dev/cciss/c0d0p1)
Kernel Modules: scsi_mod cciss hwmon thermal_sys processor thermal dock libata ata_piix ata_generic ide-core piix
ide-pci-generic fan jbd mbcache ext3 edd usbcore ohci-hcd ehci-hcd uhci-hcd ff-memless hid usbhid
Features: block usb resume.userspace resume.kernel
Bootsplash: SLES (1024x768)

Kernel image: /boot/vmlinuz-2.6.27.19-5-xen
Initrd image: /boot/initrd-2.6.27.19-5-xen

Resume device: /dev/disk/by-id/cciss-3600508b100104a39535533385142000a-part1 (/dev/cciss/c0d0p1)

2. Verify that the QLogic parameter has taken effect by issuing the following command:
# cat /sys/module/qla2xxx/parameters/qlport_down_retry
10
The example above correctly shows the qlport_down_retry setting set to 10 when the
SLES server is connecting to an HP 3PAR array running HP 3PAR OS 3.1.1 or later. However,
if the HP 3PAR array is running an HP 3PAR OS version earlier than 3.1.1, the setting should
be 1.
3. Check the contents of the /boot/grub/menu.lst with grub as the bootloader so that the
initrd maps to the correct ramdisk image.
Example:
# vi menu.lst
default <label number>
timeout 8
