When using third-party multipath software HDLM, after using parted command, the device with symbolic link /dev/disk/by-id/wwn-XX may not be the expected device

Solution Unverified - Updated -

Issue

  • Using parted -l or parted -s print command changes the symbolic link under /dev/disk/by-id/ for multipath devices and no longer points to the expected device.
# ls -l /dev/disk/by-id
/dev/disk/by-id:
lrwxrwxrwx 1 root root 13 Feb 27 12:00 wwn-0x60060e8021529d005060529d000XXXX -> ../../sddlmaa
...

# parted -l
...

$ ls -l /dev/disk/by-id
/dev/disk/by-id:
lrwxrwxrwx 1 root root  9 Feb 28 12:05 wwn-0x60060e8021529d005060529d000XXXX -> ../../sdt
