Thread: Automatically change /dev/mapper after upgrade to SLES 11 SP2 64 bits.

  1. #1

    Default Automatically change /dev/mapper after upgrade to SLES 11 SP2 64 bits.

    Hi,
    After upgrading one server SLES 11 SP1 to SP2 which has multipath in it, the file system change to use /dev/mapper/****. Before that, it use /dev/sdaN.
    I also upgrade the other servers which do not use the multipath and no SAN attached, the file system remain to use /dev/sdaN . ONLY for the server that has multipath, it suddenly change to /dev/mapper after the upgrade. Is it the new features regarding the Service Pack 2. Can someone help me on this to verify if this is normal or not and some explanation.

    Before Upgrade (SLES SP1):
    Kernel-2.6.32.12-0.7-default

    /dev/sda2 69G 39G 27G 59% /
