This document (3134230) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11
SUSE Linux Enterprise Server 10
SUSE Linux Enterprise Desktop 10

Situation

Due to problems on a SLES server you need to boot with the rescue CD and need to change data. The /-partition is not on LVM. Several other data are on LVM partitions.

Resolution

SLES 10 and SLES 11:

1. Start the system with the rescue CD
2. Login with root (no password needed)
3. Mount the / partition. E.g.mount /dev/sda1 /mnt

4. Give the command: mount -o bind /dev /mnt/dev

5. Give the command: mount -o bind /proc /mnt/proc

6. Give the command: mount -o bind /sys /mnt/sys

7. Give the command: chroot /mnt --> you could get some errors (e.g. regarding yast). Ignore these errors.

8. Give the command: mount -av

9. The LVM partitions should be available

Additional Information

Please note TID 7014112 - Symbolic links /dev/$VGNAME/$LVNAME unavailable in SLE11SP3 rescue system in case the SLE11SP3 rescue system is used.
