Host
Group
Mode
Function
Veritas Cluster Server
When a reserved volume receives a Mode
Sense command from a node that is not
reserving this volume, the host will receive
the following responses from the storage
system:
ON: Normal response
OFF (default): Reservation Conflict
NOTE:
22
CAUTION:
Changing host group modes for ports where servers are already installed and configured is disruptive
and requires the server to be rebooted.

Setting the system option modes

The HP service representative sets the system option mode(s) based on the operating system and
software configuration of the host. Notify your HP representative if you install storage agnostic software
(such as backup or cluster software) that may require specific settings.

Configuring the Fibre Channel ports

Configure the disk array Fibre Channel ports by using P9000 or XP Command View Advanced Edition
Software or XP Remote Web Console (shown). Select the settings for each port based on your storage
area network topology. Use switch zoning if you connect different types of hosts to the array through
the same switch.
When HMO 22 is ON, the volume
status (reserved/non-reserved) will be
checked more frequently (several tens
of msec per LU).
When HMO 22 is ON, the host OS
will not receive warning messages
when a Mode Select command is is-
sued to a reserved volume.
There is no impact on the Veritas
Cluster Server software when HMO
22 is OFF. Set HMO 22 to ON when
the software is experiencing numerous
reservation conflicts.
Set HMO 22 to ON when Veritas
Cluster Server is connected.
Default
Comments
NOTE:
Note:
Before setting HMO
22 ask your Hitachi
Data Systems repres-
entative for assist-
ance.
HMO 22 can be
changed while the
OFF
host is online. How-
ever I/O activity
may be affected
when it is being
changed. It is recom-
mended to stop the
host IO on the port
where you want to
change the HMO
22 setting.
