Instances of settings

This topic explains instances of settings on IMM-based servers.

The ASU extends the support of instances in several different ways. Commands have been created or modified to provide more information about instances and additional ways to create and delete them. Instances are denoted by adding a dot, followed by the instance number to the end of the setting name. For example, if the setting name is "IMM.LoginId," instance number 1 of the setting is "IMM.LoginId.1".

Note: There is an exception to the naming convention for single instances. Single instances do not have the dot followed by an instance number. The setting instead appears like a non-instance setting. Single instance settings are denoted in the output of the showvalues command by having a maximum number of instances of :"single." For example, the setting iSCSI.initiatorName is a single instance. The dot followed by an instance number is not used. If the single instance exists, the setting iSCSI.initiatorName is displayed in the show command output. If it does not exist, the setting is not displayed in the show command output.

Instance settings are defined to have a minimum and maximum number of allowed instances. To determine which settings can have instances and the minimum and maximum number of instances allowed, use the showvalues command with the --instances parameter. The output of this command is detailed in the showvalues command section.
