Incorrect mapping of snapshot and source LUNs causes VxSVC to stops working

Last published : Oct 01, 2026
After mapping of snapshot LUNs to the host containing the source LUNs or mapping of the source LUNS to the host containing the snapshot LUNs, the following issues may occur:
  • The VxSVC service goes into an invalid state and may stop working
  • The host shows "unknown DG" for the snapshot LUNs disk group
To avoid these issues, do not connect the snapshot LUNs to the same host containing the source LUNs, or the source LUNs to the same host containing the snapshot LUNs. (2871055, 2794524)
It is recommended that you use Volume Shadow Copy Service (VSS) to take a snapshot and to import the snapshot LUN, preferably on a different node.
