Mode Function
Veritas Storage Foundation for Oracle RAC,
DBE+RAC Database Edition/Advanced
2 Cluster for Real Application Clusters or if
Veritas Cluster Server 4.0 or later with I/O
fencing function is used.
This Host Group Mode can change the re-
sponse to the Host when a reserved device
has received a mode sense command unre-
lated to the Reserve. The effects of this mode
are:
1. The retry time is shortened for device
recognition (several tens of ms/LU)
Warning messages are prevented from
22
being generated in the OS log
2. Even if the option is not set ON, no op-
eration error(s) are caused for Veritas
Cluster Server Software
Host Group Mode 22 = OFF - Reserve
Conflict response
Host Group Mode 22 = ON - Normal End
response
CAUTION:
Changing host group modes for ports where servers are already installed and configured is disruptive
and requires the server to be rebooted.
