4.1.0 HP PolyServe Software for Microsoft SQL Server administration guide (T5392-96074, October 2010)
NOTE:
HP PolyServe Software uses the following rules to determine the SSAS instances that
can be assigned to the Virtual SSAS. The Name field does not include instances that
do not meet these requirements.
• The SSAS instance must exist on all of the nodes providing network interfaces
for the Virtual SSAS. (The instance must have the same name on all of the nodes.)
• The SSAS instance cannot be in use on any of the nodes as a primary for another
Virtual SSAS.
• SSAS instance on the primary node cannot currently be a backup for another
Virtual SSAS.
Virtual data root: Specify the full path for the PSFS filesystem that will be used for
the data files and directories for this SSAS instance. (In mx commands, the virtual
data root is referred to as the vpath.)
Data path, Log path: These fields display the locations of the SSAS data and log
files.
Optional Components: When you add a SSAS instance to a Virtual SSAS, HP
PolyServe Software creates a monitor that periodically checks whether the Analysis
Services NT service is up and whether the data path on the shared PSFS filesystem
is accessible on the node hosting the Virtual SSAS. When the monitor detects a failure
of the NT service, HP PolyServe Software can try to restart the service instead of
immediately failing the Virtual SSAS over to the backup node. The optional component
Restart Attempts allows you to specify the number of attempts that should be made.
The default is one attempt.
Probe Configuration: The frequency is the interval of time, in seconds, at which the
monitor runs its probe. The default setting is 20 seconds. The timeout is the maximum
amount of time that will be waited for the probe to complete. The default timeout
interval is 15 seconds.
NOTE:
The probe behavior of the Virtual SSAS instance monitor differs from the default
behavior of the service monitors provided with Matrix Server. In Matrix Server, the
monitor probes the associated service on all nodes on which it is configured. The
Analysis Services Service monitor probes the Analysis Services service only on the
node where the Virtual SSAS is active.
