NetWorker 19.7 Snapshot Management Integration Guide
Manual pairing LUNs with the symm.res file
You can use the symm.res file instead of, or also with, intelligent pairing. This file enables you to manually select mirrors to pair to specific source LUNs. SnapVX does not support symm.res. SnapVX requires targets for mounting the snapshot which you can select only by using IP.
NOTE If you do not correctly configure the
symm.res file to mask the mirrors to the mount host, NetWorker creates snapshots that are not available for restore or for clone operations.
Consider the following features of the symm.res file and intelligent pairing:
- If the symm.res file specifies a source LUN, that LUN cannot use intelligent pairing, even if none of its specified mirrors are valid or even if the symm.res file is incorrect.
- Source LUNs are available to intelligent pairing only if the symm.res file does not specify them or the symm.res file does not exist.
- You can disable intelligent pairing by specifying the Application Information variable NSR_PS_SYMM_IP=FALSE.
