sybcluster cannot find interfaces file

sybcluster may report an error message, stating that it cannot find the interfaces file in a nonexistent directory:

ERROR - The interfaces file /remote/ase_cluster/sdclinux/UAF-2_5/bin/interfaces could not be found. 

This error generally occurs when one or more UAF agents cannot access the quorum device. This may occur because:

To resolve this issue, verify that:

  1. You sourced the SYBASE.sh or SYBASE.csh files before starting the UAF agent on each node in the cluster.

  2. The quorum device exists and that the login that was used to start the UAF agent has read and write permissions on it.
