Sybase recommends that your I/O fencing use persistent
DSF on HP-UX 11.31.
Note: HPIA I/O fencing does not support the HP VM.
Run qrmutil to confirm if a disk is I/O fencing capable. See Chapter 14, “System Changes,” in
the Cluster User Guide for information about running qrmutil.
Before you enable I/O fencing, make sure the user
who starts Adaptive Server has read and write permissions for all
database and quorum devices. Use the UNIX chown, chgrp,
and chmod commands to grant the correct permissions
to the user who starts Adaptive Server.
