Attribute definitions for the TrueCopy/HP-XP-CA agent
Table: Attributes for the Hitachi TrueCopy agent lists the attributes associated with the agent:
Table: Attributes for the Hitachi TrueCopy agent
Attribute | Description |
---|---|
BaseDir | Path to the RAID Manager Command Line Interface. Type-Dimension: string-scalar Default: C:\\HORCM\\etc. |
GroupName | Name of the device group that the agent manages. Type-Dimension: string-scalar |
Instance | The Instance number of the device that the agent manages. Multiple device groups may have the same instance number. Do not define the attribute if the instance number is zero. Type-Dimension: integer |
SplitTakeover |
A flag that determines the following:
See About the SplitTakeover attribute for the Hitachi TrueCopy agent. Type-Dimension: integer-scalar Default: 0 |
User | The domain user account under which HORCM Manager is started. Type-Dimension: string-scalar |
Domain | The domain for the account specified in the User field. This user must have sufficient privileges to perform the HORCM commands. Type-Dimension: string-scalar |
Password | The password for the user account specified in the User field. You must encrypt this password by using the vcsencrypt utility. Type-Dimension: string-scalar |
LinkMonitor | A flag that defines whether the agent periodically attempts to resynchronize the S-VOL side if the replication link is disconnected. The agent uses the pairresync command to resynchronize arrays. The value 1 indicates that when the replication link is disconnected, the agent periodically attempts to resynchronize the S-VOL side using the pairresync command. If the value of the LinkMonitor attribute is set to 2, the agent generates SNMP traps or alerts when the status of the attached P-VOL and S-VOL changes. If the status of the configured HTC device changes to PSUE, PSUS, SSUS, or SSWS, the agent generates an SNMP trap indicating that the resource health has gone down. For all other types of status changes of the configured HTC devices, the agent generates an SNMP trap indicating that the resource health has improved. An error or information type message is logged by the agent in the VCS HIgh Availability engine log- "The state of P-VOL/S-VOL devices in device group device group name has changed from previous state to current state." Setting LinkMonitor does not affect the SplitTakeover behavior. However, you can minimize the time during which the P-VOL is in the PSUE state by setting the LinkMonitor attribute. Type-Dimension: integer-scalar Default: 0 |
RoleMonitor | Determines if the agent must perform detailed monitoring of HTC volumes. If this attribute is set to 0, the agent does not perform detailed monitoring. This attribute is disabled by default. If this attribute is set to 1, the agent monitors the status of the HTC volumes everytime a monitor cycle runs. In addition, the HTC resource comes online only when any of the following conditions are met:
Type-Dimension: integer-scalar Default: 0 |
FreezeSecondaryOnSplit | A flag that determines if the agent must freeze the service group in the remote cluster when the TrueCopy replication link is either split or suspended. The value 1 indicates that the agent must freeze the service group in the remote cluster when the replication link is split or suspended. Type-Dimension: integer-scalar Default: 0 |
AllowOnlineOnSimplex | A flag that determines if the agent must allow a resource to come online when the TrueCopy devices are in SMPL (Simplex) state. This attribute is honored only when the agent attempts to bring a resource online. The value false indicates that the agent must not allow a resource to come online when TrueCopy devices are in SMPL (Simplex) state. Type-Dimension: boolean-scalar Default: false |
TargetFrozen | For internal use. Do not modify. |
AdvancedOpts | Used at the time of monitoring. This attribute enables the agent to execute a custom script during the monitor cycle of the resource. Use the AllowAutoFailoverInterval attribute with this attribute. The agent automatically fails over if certain conditions are met and AllowAutoFailoverInterval is set to 0 (zero) or a positive integer. To disable the execution of the custom script, set AllowAutoFailoverInterval to undefined or remove it from the AdvancedOpts attribute. For example: AdvancedOpts{} = { AllowAutoFailoverInterval="undefined" } Type-Dimension: string-association |
AllowAutoFailoverInterval | The agent uses this attribute to fail over automatically only if all the following conditions are met:
The failover takes place only if the value of this attribute is greater than the last registered PAIR state time difference. Note: This attribute is applicable only when the fence level is NEVER. Default: undefined Type-Dimension: string-association |
PVOLStateTime | This is an internal attribute that is used to maintain the P-VOL state and the timestamp when the instance was last registered as PAIR. Note: Do not modify this attribute. |
