mkinitrd fails with perl-bootloader, no partition found errors

This document (7009728) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11
SUSE Linux Enterprise Desktop 11

Situation

Attempting to create a new ramdisk fails.
ERROR: "perl-bootloader: 2011-11-03 08:13:49 WARNING: GRUB::GrubDev2UnixDev: No partitions found for /dev/sda with 1."
A new ramdisk is created and the server seems to boot without a problem.

Resolution

Recreate the /boot/grub/device.map file.

1. cd /boot/grub/
2. mv device.map device.map.old
3. grub
4. At the grub> prompt, type quit
5. Rerun mkinitrd, it should no longer have the perl-bootloader errors.

Additional Information

The per-bootloader errors are due to incorrect device.map mappings. Removing /boot/grub/device.map forces grub to reprobe the BIOS for the disk devices and write the (hd) to /dev/ (GrubDev2UnixDev) mappings to a new device.map file.

There has also been a case where reprobing the BIOS failed to write the correct information to the /boot/grub/device.map file. A /dev/cciss/c0d0 was written to /boot/grub/device.map as /dev/sda1. After manually editing the device.map file with the correct /dev/cciss device, no further perl-bootloader errors were seen.
