HP StorageWorks P9000 Cluster Extension Software Administrator Guide (TB534-96009, February 2011)

Objects have one of the following formats:
A definition of an object; for example, COMMON or APPLICATIONtag
A number; for example, a timeout valueinteger
A name, which can include alphabetic and numeric characters and underscores; for example, an
application startup value
string
A list of space-separated strings, for example, a list of host names (lists of numbers are stored as lists
of strings)
list
Text that is a comment starts with the pound (#) symbol and continues until the end of the line.
Comments can start on a new line or be part of a line specifying an object.
Specifying object values
When using the default configuration, you must provide values for the following objects:
• DeviceGroup: A RAID Manager device/copy group
• DC_A_Hosts: A list of the cluster nodes in data center A
• DC_B_Hosts: A list of the cluster nodes in data center B
• RaidManagerInstances: A list of RAID Manager instances that P9000 Cluster Extension can
use to communicate with the disk array
• XPSerialNumbers: The serial numbers of the primary and secondary disk arrays
You do not need to change the default settings unless you want to change the degree of protection
for your paired disks. If you change an object, you may need to change additional related objects.
For example, if you change the FenceLevel object to DATA, you might need to change the
DataLoseMirror object.
Objects are supported according to the requirements or capabilities of the cluster software, as
shown in “Cluster software supported objects” (page 80).
