2. Edit the following attributes in the temp.config file:
a. dts/dts/dts_pkg_dir - This is the package directory for this Metrocluster Modular
package. The Metrocluster Environment file is generated for this package in this directory.
This value must be unique for all packages.
b. DEVICE_GROUP - Specify the device group name managed by this package, as specified
in the RAID Manager configuration file.
c. HORCMINST - Specify the name of the RAID manager instance that manages the device
group used by this package.
d. FENCE - Specify the fence level configured for the device group that is managed by this
package.
There are additional Metrocluster parameters available in the package configuration file. HP
recommends that you retain the default values of these variables unless there is a specific
business requirement to change them.
For the failover_policy parameter, Metrocluster failover packages can be configured to
use any of the Serviceguard defined failover policies. The site_preferred and
site_preferred_manual failover policies are introduced in Serviceguard specifically for
Metrocluster configurations.
The site_preferred value implies that when a Metrocluster package has to fail over, it
will failover to a node in the same site as the node it last ran. Only when there is no other
configured node available within the same site, the package fails over to a node at the other
site.
The site_preferred_manual failover policy provides automatic failover of packages
within a site and manual failover across sites.
Configure a cluster with sites to use either of these policies. For information about configuring
the failover policy to site_preferred or site_preferred_manual, see “Site Aware
Failover configuration” (page 18).
3. If you want to monitor the status of the device group pairs, configure Device Group Monitor
(DGM). Otherwise, skip this step. To configure Device Group Monitor, the Serviceguard
module sg/service must be included while creating a Metrocluster package configuration file.
a. Configure the parameters for the Device Group Monitor in the package configuration
file.
Table 4 Device Group Monitor Parameters
DESCRIPTIONPARAMETERS
Specify the polling interval for the DGM. If the parameter is not
defined (commented out), the default value is 10 minutes. Otherwise,
the value is set to the desired polling interval in minutes.
MON_POLL_INTERVAL <polling
interval in minutes>
Specify the value for MON_NOTIFICATION_FREQUENCY . This
value is used to control the frequency of notification message when
MON_NOTIFICATION_FREQUENCY
<frequency of notification
message>
the state of the device group remains the same. If the value is zero,
the monitor sends notification when the state of the device group has
changed. If the value is set to n where n is greater than 0, the monitor
sends a notification every nth polling interval or when the device
group state has changed. If the variable is not set, the default value
is 0.
If you want to receive notification messages over e-mail, specify the
fully qualified e-mail address. You can specify multiple e-mail address
separated by a comma.
MON_NOTIFICATION_EMAIL
<e-mail id>
