Offline Upgrade SLES 12 SP5 to 15 SP5 Fails

  • The upgrade process does not detected any partition to update.
  • If we select show all partitions it shows the SLES 12 SP5 partition but after the selection and press continue it gives /mnt/boot/efi mount failure.

  • How can we handle this? Thanks in advanced.

  • Hi All,
    After some google searching it seems to me that the problem is related with the use of the HPE driver cciss that must be changed to hpsa in /etc/fstab before the upgrade.

    I have scheduled for the next friday (11/06/2021) to make a new upgrade attempt and after the intervention i will post the result.

    System.:
    * HPE Proliant DL580 G9 + SLES 12 SP5 for SAP

    Hi All,
    Intervention in progress ...

  • Hi all,
    Changing the file /etc/fstab from cciss to hpsa worked in conjunction to the change made to the GRUB menu, adding hpsa.hpsa_allow_any=1 parameter at ISO boot.


    But now we face the following issue.

    Hi All,

    Offline Upgrade SLES 12 SP5 to 15 SP2 done successfully!

    1. In the file /etc/fstab we changed all mount points from cciss to hpsa;
    2. Downloaded and make the boot with SLE-15-SP2-Online-x86_64-GM-Media1.iso file;
    3. When GRUB menu appears select T, select Upgrade, CTRL+e to edit, and add the hpsa.hpsa_allow_any=1 parameter;
    4. CTRL+x to save and start the Upgrade;
    5. When asked fill the network settings and proceed with the Upgrade (make sure you have internet access);

    Note.: After the upgrade we had to reconfigure the name servers.
