Serviceguard Extension for RAC Version A.11.19 Release Notes, March 2009

configuration files such as /etc/fstab and /etc/lvmtab will contain references to persistent
device files, but Serviceguard’s functioning will not be affected by this.
CAUTION: You cannot migrate to the agile addressing scheme during a rolling upgrade if you
are using cluster lock disks as a tie-breaker, because that involves changing the cluster
configuration. But under certain conditions, you can migrate the cluster lock device file names
to the new scheme without bringing the cluster down. For the requirements and a procedure,
see the section “Updating the Cluster Lock Configuration” in chapter 7 of the Managing
Serviceguard Sixteenth Edition user’s guide.
NOTE: It is possible, though not a best practice, to use legacy DSFs on some nodes after migrating
to agile addressing on others; this allows you to migrate different nodes at different times, if
necessary.
