Snapdrive for Unix

SnapDrive for UNIX operations fails due to improper multipath settings when aliased devices are used.


When you run the storage show or snap create command in RHEL 5.11, the command displays the following error message:

Status call to SDU daemon failed and in SLES11SP3 host with --nolvm option when the host LVM is not involved.

  • snapdrive storage show -all command fails to show proper alias name

    SnapDrive for UNIX does not show proper alias name for the mapper devices. This issue occurs when multipaths{ } section is not proper in the multipath.conf file.

  • Workaround

    You must ensure that closing braces are entered in the multipath settings.

  • SnapDrive operations fails with the below error when the alias names has been set for the mapper devices

    Snapdrive could not import /dev/mapper/lvm_fs_SdDg:   device-mapper: resume ioctl failed: Invalid argument
      Unable to resume lvm_fs_SdDg-lvm_fs_SdHv (252:4)   1 logical volume(s) in volume group "lvm_fs_SdDg" now active”

    This issue occurs when the alias name mapping with the devices is not proper.

  • Workaround

    Perform multipath-ll and make sure that the alias name mapping with the devices is proper, and then perform the SnapDrive for UNIX operations.
